LASIK, LASEK & SMILE — Do You Really Know What You're Getting Into? Ask a Practicing Surgeon!BGN Eye Clinic · Dr. Kim Jeong-wanHello, I'm Dr. Kim Jeong-wan of BGN Eye Clinic, Jamsil Lotte World Tower.Today, I want to address some of the questions I've heard most often over the years of performing and consulting on LASIK and SMILE procedures. I'll be digging into them one by one right here on the blog.Because vision correction procedures — SMILE, LASIK, LASEK, and the like — have a clear purpose and a well-defined process, the questions patients and their families ask tend to overlap a lot. So much so that midway through a consultation, I can usually sense exactly what someone is about to ask before they even say it. (I've just done too many of these… 😅)With that in mind, I decided to write this up properly — so thoroughly that next time someone asks, I can just send them the link instead of answering from scratch. Here are my honest answers as a practicing surgeon.Fun fact: one of my old friends — someone I personally performed SMILE on last year (2024) — asked three of the exact same questions I'm covering today. That was all the confirmation I needed that patients' concerns are remarkably universal.Alright, let's get into it!Q1. If You've Worn Contact Lenses, You Can't Get LASIK?NO!During our busy winter and summer seasons when patients come in for pre-operative exams, one of the very first things I hear is something like this:"Doctor, I've been wearing contacts for years… is that going to be a problem? 😢"The short answer: absolutely not! 😄 To be precise, whether contact lens use will affect your eligibility for surgery is something we simply "cannot determine in advance" — because there is no direct causal relationship between the two.For example, if all other factors (corneal thickness, degree of dryness, etc.) are within acceptable ranges, the fact that someone has worn lenses for a long time does not disqualify them from surgery. Conversely, someone who has never worn a lens in their life is not automatically eligible if other conditions aren't met. Simply put: contact lens history and surgical eligibility are completely independent of each other.That said, there is one thing worth noting: in some cases, the physical habit of inserting and removing lenses has caused significant corneal damage over time. If that process repeatedly stressed the cornea in an unhealthy way over many years, then the cornea's health and resilience need to be carefully assessed before proceeding with LASIK or SMILE.The good news: this is almost always caught during the pre-operative examination phase, so there's really no need to worry ahead of time. At our clinic, one of our 11 diagnostic machines is the Pentacam — when a patient goes through that test, the results come directly to me or one of our other surgeons, and that's where we'd identify any issues of this kind.So to summarize: wearing contact lenses has no bearing on your eligibility for SMILE, LASIK, or LASEK. The exception: if prolonged improper contact lens use has weakened the cornea to a problematic degree, that will show up in the examination.As long as you've been wearing lenses the right way — stopping lens wear for just a few days to a week before surgery is typically enough for the cornea to recover its natural shape. Nothing to worry about! (Note: that timeline applies to soft lenses. Hard lenses take a bit longer — plan for about 2 weeks.)Conclusion: Even if you've worn contacts for 20 years — as long as you stop wearing them and give your cornea enough time to return to its natural shape before surgery, LASIK, SMILE, and LASEK are all perfectly fine. (The only exception: if improper lens use has caused extensive corneal damage, that becomes a separate issue to address.)Q2. Are Dedicated Eye Clinics Better at LASIK Than Large General Hospitals?It depends…This one is both a No and a Yes at the same time. What I mean is: the single most important factor in vision correction surgery — SMILE, LASIK, LASEK — is the operating surgeon's experience.Here's an analogy. I'm a doctor, but I get sick too. When I do, I naturally want my doctor to have as much experience and clinical mileage as possible. It just builds trust. The same logic applies to LASIK, LASEK, and SMILE.What makes vision correction surgery particularly interesting is that it's performed at an exceptionally high volume in Korea every year. That means certain clinics have built up a truly overwhelming accumulation of surgical experience. The sheer number of SMILE, LASIK, and LASEK procedures performed annually far exceeds that of something like spinal neurosurgery.With that depth of experience, a seasoned clinic and surgeon have seen it all: the full range of pre-operative data, the statistical variance, the edge cases, the potential risks, and even the unexpected patient movements mid-procedure. Every small detail — the patient flow, the way instructions are phrased, the surgical tools, the examination sequence — is refined through data and repetition. That's why, as a practicing surgeon, I'm confident saying: experience-rich clinics are simply the best option.When It Comes to Your Eyes, Thorough Examination Is Non-NegotiableThere's another term that tends to carry an unfair stigma: "assembly-line surgery." Apply that phrase to someone's eyes, and it understandably sounds alarming — cold, impersonal, rushed.But if you actually look at what's being described, "assembly-line" is really shorthand for:A perfectly defined procedure followed from start to finishEstablished through extensive research and trial and errorRepresenting the safest, most reliable surgical pathwayExecuted consistently and without deviation, like a well-oiled machineEven the most experienced expert in any field can have an off day — skipping steps, cutting corners based on mood or circumstances. In most fields, that's unfortunate. In medicine, it can be catastrophic. That's why adhering to a defined, safe, and precise process matters enormously — and that kind of consistency is only possible when the volume of procedures is high enough to truly systematize the process.So rather than "assembly-line surgery," I'd call it "protocol-driven surgery." When every step is pre-set and calibrated to the patient's individual examination results, it becomes possible to perform surgery safely across a very wide range of patients — and that translates directly into an ever-growing archive of clinical experience.To wrap up: whether it's a large general hospital, a university hospital, a neighborhood eye clinic, or a dedicated LASIK center — the best place to go is simply the one with the most surgical experience.Conclusion: The best clinic for surgery is one with a high surgical volume, an experienced surgeon, and the infrastructure and systems in place to let that surgeon perform at their best — without interference.Q3. Do Clinics Run Too Many Tests Before SMILE or LASIK?NO!On this one, as a practicing surgeon, I want to say unequivocally: absolutely not. Never.Even at our own clinic, the full pre-operative examination for SMILE, LASEK, LASIK, and ICL follows a set course — and yes, it involves a lot of steps and takes some time. We run about 11 different tests, including Optos imaging and Pentacam. Occasionally, something unusual or unexpected is detected during testing — something the patient had no idea about — and we may need to refer them for additional tests or to another specialist.But skipping tests? If someone asked me to do that, I wouldn't perform the surgery. It's not that I wouldn't — I genuinely can't. As a doctor, this is not a matter of preference; it's a matter of basic medical responsibility.Without knowing the precise state of your eyes, it would be medically indefensible for me to say "LASIK is fine" or "SMILE is the better choice." To make any kind of medical judgment without that data — or with incomplete data — would violate the very oath every doctor takes when they receive their license.Take the Pentacam, for example — one of the essential pre-operative tools. With it, we can evaluate:The full shape of the corneaThe curvature of the entire cornea and its precise anglesThe condition and morphology of both the anterior and posterior corneal surfacesThe anterior lens interface and every surrounding boundary zoneCorneal thickness, volume, and depth across multiple layersAnd the reason we need all of that? Because we are literally reshaping that cornea. The core action in LASIK and SMILE is removing a precise layer of corneal tissue. To do that safely, we need to know the exact topography and dimensions of what we're working with — otherwise:Remove too much → We may encroach on unsafe territory, leading to potential complications later.Remove too little → Vision may not reach the desired level of correction.Remove incorrectly → Light refraction and visual quality may be compromised.Comprehensive testing is what allows us to avoid all of the above. So even if the examination process feels long and a little tedious, I hope patients and their families can embrace it with patience. After all — this is your eyes we're talking about.Conclusion: Vision correction examinations are never excessive — if anything, doing too little is the real risk! Even if the process feels lengthy, every single test is necessary for a safe outcome and the best possible vision.Q4. Is Winter Better for Surgery? Should You Avoid Getting It Done in Summer?NO!There is no meaningful difference. The surgery itself — LASIK, SMILE, LASEK — is completely unaffected by the season. Someone once asked me: "Isn't it true that summer humidity makes the cornea expand after surgery, so you shouldn't get it done then?" Nope. That's not a thing.The procedure itself is not influenced by whether it's summer or winter. Within the temperature range that humans inhabit, there's simply no issue. So why is there a small nuance when you look at the full picture?The answer is lifestyle habits. In summer, compared to winter, there are far more opportunities for things to get into your eyes — and more chances to rub or touch them. What kinds of things end up in your eyes in summer?Sea waterSweatRainIn summer, people shower more frequently, there are more insects, and when it's hot and itchy, people reach for their eyes without thinking. The surgery in summer is perfectly fine — but the lifestyle that comes with summer carries a slightly higher potential for accidental eye contact.Think about how much more we're outdoors in summer — riverside hangouts, beer gardens, barbecues, vacations, the beach, water parks… All of that excitement puts people in an elevated, carefree mood, which means they're more likely to absentmindedly rub their eyes. And that's precisely why summer deserves a bit more caution post-surgery.Conclusion: Temperature and humidity in summer vs. winter? Not an issue at all. But the energy and excitement of summer can lead to unconsciously touching your eyes more often — and that's the real concern! (If you have the self-discipline to resist that… then you have nothing to worry about.)Wrapping Up…!I've done my best here to tackle four of the most persistent myths and misconceptions I encounter about SMILE, LASIK, and LASEK — with as much detail as I could pack in as a practicing surgeon. There's always so much more I want to say during consultations, but the nature of clinical appointments means sticking to what's directly relevant to each patient. This blog is where I get to ramble a little, connect the dots, and give you the full reasoning behind each answer.As I was writing this, a few more frequently asked questions came to mind:Is there a big difference in visual outcomes between LASIK and SMILE?Can your vision deteriorate again after LASIK?Does it cause early-onset presbyopia?Since this is already getting quite long, I'll stop here and continue with more myths and questions in Part 2. It's peak surgery season right now, and seeing so many patients leave our clinic with a whole new perspective — literally — is one of the most rewarding parts of this work. Wishing everyone bright, healthy eyes!

The Complete Guide to SMILE Pro A to Z:SMILE Pro vs. SMILE — What's the Difference?A Premium Vision Correction Guide from BGN Eye Clinic, Jamsil Lotte World TowerHello. This is BGN Eye Clinic ,Jamsil Lotte World Tower.I still vividly remember the first time I heard the name "SMILE Pro." At a medical conference, when it was described as "an upgraded version of SMILE," I'll be honest — I was skeptical. I thought, "How much better could it really be than standard SMILE?" and "Will patients actually feel a noticeable difference?"But when I got hands-on with the actual equipment and performed my first case, the feeling was unmistakably different. I had the clear conviction: "This is genuinely a step forward." Today, I'd like to walk you through what SMILE Pro is all about, drawing from what I've personally experienced and observed in the clinic."Doctor, contact lenses make my eyes feel dry so quickly.""Wearing glasses with a mask fogs everything up — it's so frustrating.""If I need a whole week off to recover, surgery just isn't realistic for me…"When I hear "Is there a procedure with a fast, easy recovery?", I find myself nodding along. And these days, the word that comes up most often in my consultations is "SMILE Pro." Beyond LASIK, LASEK, and standard SMILE, this next-generation procedure has been generating incredible excitement among patients.In this article, I'll cover the key questions many of you may have:1. How SMILE Pro works and what makes it different2. Its advantages and limitations compared to LASIK, LASEK, and SMILE3. What the post-operative recovery process actually looks like, step by stepHow SMILE Pro WorksSMILE Pro is fundamentally the same as standard SMILE in that it uses a small-incision lenticule extraction approach. However, the laser technology behind it has taken a significant leap forward — and that's the key.What Is Lenticule Extraction?This technique involves precisely cutting and removing only the thin layer of corneal tissue that needs to be corrected. Unlike LASIK, there's no large corneal flap; unlike LASEK, the epithelium isn't fully removed. Instead, a femtosecond laser creates a thin, disc-shaped piece of tissue (the lenticule) inside the cornea, which is then extracted through a tiny incision of about 2mm.The size of that incision matters enormously. LASIK requires an incision of roughly 20mm, standard SMILE uses 3–4mm, but SMILE Pro reduces this to an average of just 2mm. This seemingly small difference has a major impact on recovery time and post-operative discomfort.The Laser UpgradeThe most significant advancement SMILE Pro offers over standard SMILE is in laser speed and precision.• Standard SMILE: Approximately 25–28 seconds• SMILE Pro: Approximately 10 seconds or lessWith the procedure time cut by more than half, the psychological burden of having to fixate on the laser light is greatly reduced. I like to explain it this way: if standard SMILE was 4G, SMILE Pro is the 5G upgrade.A Step-by-Step Look at the SMILE Pro Procedure1. Laser Planning After Eye Examination — Custom-Designed for Your EyesBefore surgery, a comprehensive examination measures corneal thickness and astigmatism axis, among other parameters. Based on this data, the laser system is automatically calibrated to the exact correction values needed for your eyes. Think of it like a bespoke suit — a "blueprint made just for you" is prepared in advance.Corneal endothelial cell count is a mandatory check. If the count is too low, vision correction surgery may carry additional risk, so this must always be confirmed beforehand.2. Lenticule Creation — Sculpting Within the CorneaThe femtosecond laser fires to create a thin, disc-shaped lenticule at the precise depth within the cornea. This step typically takes around 10 seconds and involves virtually no pain. If your eye moves slightly, the laser automatically compensates — so there's no need to worry.3. Micro-Incision — Opening Just 2mmIf LASIK is like lifting the entire roof off a house to make repairs, SMILE Pro is like opening a tiny hatch and removing only what needs to come out. With only a 2mm opening, there's virtually no visible wound on the surface, and recovery is remarkably fast.4. Lenticule Removal — The Moment Vision Is CorrectedUsing a delicate microsurgical instrument, the surgeon carefully extracts the lenticule. This is the moment the vision correction takes effect. No sutures or bandage contact lenses are needed — the eye naturally stabilizes within about a day.The Benefits of SMILE Pro — Why Are Patients Paying Attention?Greater Nerve Preservation Means Less Dry EyeLASIK's flap creation severs a significant number of corneal nerves, which can lead to chronic dryness and irritation. SMILE Pro's 2mm micro-incision minimizes nerve damage, which means patients spend far less time relying on artificial tears afterward.Superior Structural Integrity of the CorneaBecause the strong anterior corneal layers remain intact while only the internal lenticule is removed, the cornea maintains better resistance to external impact. This makes SMILE Pro especially well-suited for athletes, military personnel, and police officers with active lifestyles.Better Quality of Vision, Not Just QuantityThe more uniform laser cutting reduces internal light scattering within the cornea. Patients report very high satisfaction with reduced glare and halos during night driving and other low-light activities.Real Patient Stories — Why They Chose SMILE ProCase 1. University Student During Exam Season: A student whose contact lens dryness was interfering with studying. Returned to the library the very next day with clear, comfortable vision — satisfaction was extremely high.Case 2. A Busy Professional: Someone who couldn't afford to take extended time off. Had surgery on Friday evening and was back at work on Monday — now enjoying daily life without glasses.Case 3. Athletes and Military Personnel: Those who were anxious about the risk of impact injury. Chose SMILE Pro for its flap-free structural safety and are now fully focused on training.Pre- and Post-Operative Care Guide for SMILE ProBefore Surgery• Discontinue contact lens use: Stop wearing soft lenses at least 1 week before, and hard lenses at least 2 weeks before, to ensure accurate corneal measurements.• No eye makeup on the day: Residual mascara, eyeliner, and similar products can interfere with examination accuracy.• Optimize your condition: Get adequate sleep and stay well-hydrated to keep your eyes in their best possible state.Post-Surgery Recovery Timeline• Day of surgery: Avoid rubbing your eyes firmly and apply prescribed eye drops on schedule.• First week: Take care to keep water out of the eyes directly and attend all scheduled follow-up visits.• One month: Swimming and vigorous exercise become possible again. Use artificial tears frequently in dry environments. SMILE Pro is a procedure with many clear advantages, but it is not unconditionally the right choice for everyone. For those with very high myopia or an unusually thin cornea, the safest approach will depend entirely on their individual eye condition.Finding the safest and most suitable procedure for your own eyes is what matters most. Through accurate information and thorough examination, we are here to help you make the best possible decision for your precious vision. We wish you all bright, clear eyes — thank you.The time for your vision to go "Pro" — BGN is with you every step of the way.

LASIK vs. Lens Implant Surgery:You're Eligible for LASIK — So Why Choose an Implant?An Honest Consultation Story from BGN Eye Clinic, Jamsil Lotte TowerHello! This is BGN Eye Clinic, Jamsil Lotte Tower.There's a thought I often have during consultations: "They're a good candidate for laser surgery — so why are they set on lens implants?"The more I explain, the more I see the anxiety behind that question, the misconceptions, and the financial concerns. So today, I'd like to share some honest thoughts as an optometrist. If you're weighing LASIK against lens implant surgery, I hope this gives you something useful to think about.When I Walk Patients Through Their Options…Lens implant surgery is a great procedure — but it's not the right fit for everyone. I always make a point of explaining that "more expensive doesn't automatically mean better."Because an artificial lens is being placed inside the eye, the eligibility criteria need to be evaluated even more carefully than for laser surgery. Factors like glaucoma, cataracts, and the risk of external impact all need to be considered. On the other hand, laser procedures (SMILE, LASIK, and LASEK) work by reshaping the cornea — which means they're relatively more resilient to external impact, involve a shorter procedure time, and generally offer a faster recovery.When Patients Ask, "Which One Is Better?"…As an optometrist, here's what I tell them:"What we need to look at first is which surgery is safer and more suitable for your eyes specifically."Corneal Thickness and Lifestyle ConsiderationsThin cornea: Lens implant surgery may be worth consideringHigh-impact occupation or active in sports: Laser surgery is typically recommendedConcerned about glare or halos: Can often be addressed through surgical optionsBecause lens implant surgery involves placing a lens inside the eye, there is a risk of inflammation or other complications — and the eye can be more vulnerable to external impact. These days, with fitness challenges and active lifestyles more common than ever, I do see patients come back for revision surgery after incidents like taking a basketball to the eye.That's why, when a patient proceeds with lens implant surgery, I always advise them to be especially careful during physical activity and to avoid getting water near their eyes."Honest, Straightforward Advice"This is actually the part I'm most careful about during consultations. Some patients come in having heard from friends that "lens implants are semi-permanent, so they're always the better choice" — and they've already made up their minds. But when we run the detailed examinations, I often find that corneal thickness, corneal shape, intraocular pressure, pupil size, and corneal endothelial cell count all point toward laser surgery being significantly safer for that individual.Safety Comes Before NumbersThat's why I never present one procedure as the ideal choice during a consultation. I always explain both the advantages and the limitations of each option — honestly. At our clinic, we objectively analyze each patient's individual eye condition and use one primary criterion: which procedure can be performed most safely, with the least risk and burden for that patient.Ultimately, the final decision belongs to the patient. But our role in the consultation room is to make sure that decision is made with complete, accurate information — and with a balanced, objective perspective.When I first started out, I'll be honest — my goal was simply to explain things accurately and answer every question without hesitation. But at some point, I found myself thinking during consultations: "If this were my family, what would I say? If this were my mom or dad, which surgery would I recommend?"Now, I don't just want to be someone who passes along information. I want to be someone patients genuinely trust — someone they feel comfortable putting their vision in the hands of.And That's Why I Take Every Consultation SeriouslyThe role of an optometrist might seem, on the surface, like someone who measures vision and reads data. But every day I'm reminded: the weight of a single sentence said in that consultation room far exceeds the weight of any number on a chart. Consultations with patients considering surgery — whether lens implants, LASIK, or LASEK — are pivotal moments that can shape a life-changing decision, so I choose every word carefully.It's my role — and my responsibility — not just to highlight the benefits, but to walk through every variable worth considering. To give medically accurate explanations, and to offer advice grounded in the patient's real-world experience, I review clinical data every day, study case histories, and keep learning. Today, like every day, I'm still studying.We'll give you an honest comparison of the pros and cons of each procedure.

BGN Eye Clinic – Jamsil Main BranchSuspect High Myopia?Symptoms to Correction Methods — A Complete GuideIf your vision is blurry and your eyes feel constantly strained, high myopia may be the cause. Here is an overview of the key symptoms, correction options, and the criteria to consider when choosing a surgical method.What Is High Myopia? Definition & CharacteristicsMyopia is a refractive error in which distant objects appear blurry, and its severity is measured in diopters (D). A prescription of -9D or higher (sometimes defined as -10D or higher) is generally classified as "high myopia." It is considered a stage beyond simply having poor vision — one that can affect the structural integrity of the eye itself.Ordinary myopia can be corrected to a reasonable degree with glasses or contact lenses. However, high myopia is often accompanied by an excessively elongated axial length (the length of the eyeball), which increases the risk of thinning of the retina and the development of complications.Difference from Ordinary MyopiaOrdinary myopia (roughly -3D to -6D) can be easily corrected with glasses or contacts. High myopia, however, frequently involves structural changes to the eye, which means precise diagnostic testing is absolutely essential when selecting a surgical approach.Symptoms of High MyopiaHigh myopia can be accompanied by a range of eye symptoms beyond simple vision loss. If any of the following symptoms persist, it is strongly recommended that you undergo a comprehensive eye examination.Severe Vision Deterioration — Even with glasses or contacts, corrected vision may be insufficient, and night vision in particular may be notably poor.Floaters (Myodesopsia) — Spots or thread-like shapes that appear to drift across the visual field. In high myopia, floaters may appear at an earlier age and more frequently.Photopsia (Light Flashes) — The perception of flashing lights even in the absence of an actual light source. This may be caused by vitreous traction on the retina and warrants careful attention.Visual Field Obstruction — If part of your visual field appears blocked or covered by a dark curtain, this may be a sign of a retinal abnormality and requires immediate examination.Increased Eye Fatigue — Eyes tire quickly after near-distance tasks such as reading or using a smartphone, often accompanied by headaches.Increased Risk of Complications — If left unaddressed, high myopia can progress to serious complications including retinal detachment, glaucoma, and macular degeneration. Regular eye check-ups are essential.Correction Methods for High MyopiaSurgical correction for high myopia varies depending on the individual's eye condition. The most appropriate method — SMILE, ICL (Implantable Collamer Lens), or LASEK — is selected after a comprehensive evaluation of factors including corneal thickness, ocular structure, and lifestyle.SMILESMILE uses a laser to precisely reshape the interior of the cornea through a small incision. It is characterized by a fast recovery time and a low risk of dry eye due to the minimal incision involved.For very high myopia (-10D or above), there may be limitations to the correctable range; generally, correction of approximately -8D is possible. However, it is only applicable when sufficient corneal thickness can be confirmed, so a thorough examination and detailed consultation with your physician are necessary.ICL (Implantable Collamer Lens)ICL surgery involves implanting a specialized lens inside the eye without removing any corneal tissue. It is a valuable alternative for patients whose corneas are too thin or whose myopia is too high for LASIK or LASEK.Even in cases of high myopia, ICL covers a wide correctable range, making it an option for many patients. Another key advantage is that the lens can be removed if needed. However, there must be sufficient space inside the eye (anterior chamber depth) for the procedure to be performed safely.LASEKLASEK involves reshaping the surface of the cornea and does not create a corneal flap, which reduces the risk associated with external impact.It may be selected for high myopia patients who lack sufficient corneal thickness for other procedures but still meet the criteria for LASEK. However, the initial recovery period is longer — approximately 1 to 3 months — and may involve some discomfort during healing. Strict post-operative care, including UV protection, is required.Comparison of Surgical Methods at a GlanceThe table below summarizes the key differences between the three surgical options. Rather than declaring one method superior, it is important to understand that the optimal approach depends entirely on each individual's eye condition.CategorySMILEICLLASEKSurgical MethodLaser reshaping of corneal interiorLens implanted inside the eyeSurface ablation of the corneaApplicability for High MyopiaLimited (up to approx. -8D)Possible (wider range)Conditionally possibleRecovery Period1–2 days1–2 days1–3 monthsRecommended ForPatients with adequate corneal thicknessThose with high prescription or thin corneasThose with insufficient corneal thickness who meet LASEK criteriaCriteria to Consider When Choosing a ProcedureCorrective surgery for high myopia is not determined by prescription numbers alone. The safest and most effective method is chosen through a comprehensive assessment of the individual's corneal condition, ocular structure, and lifestyle.Corneal Thickness & Shape — If the cornea is thin or irregularly shaped, LASIK or SMILE may not be appropriate. A corneal thickness measurement should be performed first to determine a safe ablation range.Ocular Structure (Anterior Chamber Depth, etc.) — ICL requires sufficient space within the eye for safe implantation. Whether the procedure is feasible is determined by precise test results, including anterior chamber depth and corneal endothelial cell count.Lifestyle & Occupational Environment — Those with high physical activity levels or frequent physical contact may benefit more from procedures that do not create a corneal flap. Recovery time and its impact on work or study schedules should also be factored in.Comparative Consultation: LASEK vs. Other Methods — No single method is universally superior. The right surgery can differ between two patients with identical prescriptions. It is strongly recommended to make the final decision only after reviewing your full diagnostic results with your physician.High myopia extends beyond a simple vision problem — it is associated with a range of potential complications involving the retina, glaucoma, and more. At BGN Eye Clinic – Jamsil Main Branch, we conduct precise diagnostic evaluations to accurately assess each patient's individual eye condition and help identify the safest corrective approach together. If you are concerned about any symptoms, we encourage you to consult a specialist today.

Vision is something many of us take for granted—until it slowly begins to fade.For many people over 50, this change happens gradually. Colors may appear dull, night driving becomes difficult, and reading small text requires stronger glasses every year. Often, these symptoms are signs of cataracts, one of the most common eye conditions worldwide.Recently, a patient named Yvette, originally from Sydney, Australia and currently living in Seoul, shared her experience after undergoing cataract lens replacement surgery at BGN Eye Clinic. Her story is not only inspiring but also highlights how modern cataract treatment can dramatically improve quality of life. Let’s explore both her journey and what cataract surgery actually involves.When Vision Slowly Starts to ChangeCataracts occur when the natural lens of the eye becomes cloudy. The lens normally works like a camera lens, focusing light onto the retina so we can see clearly. Over time, proteins inside the lens begin to break down and form cloudy areas.A Life-Changing ProcedureFor Yvette, cataract surgery was more than just a medical treatment.It restored clarity, confidence, and independence in daily life.Her words summarize the experience perfectly: “It’s been a life changer.” Modern cataract surgery has transformed millions of lives around the world. With advanced surgical techniques and next-generation intraocular lenses, patients today can achieve levels of visual quality that were once impossible. And sometimes, as Yvette described it, the result truly does feel a little like magic.Contact BGN Eye ClinicIf you would like to learn more about cataract surgery or schedule an eye examination, please contact us:📧 Email: info@bgneyeclinic.com📱 Phone / Messaging: +82-10-3435-5770(WhatsApp · Telegram · KakaoTalk · iMessage) #cataracat #lensereplacementsurgery #presbyiopia  

Understanding Presbyopia and Age-Related Changes in the EyeMany people who consider vision correction procedures such as LASIK, SMILE, or LASEK often ask a similar question during consultation:“Can I still undergo laser vision correction after the age of 45?”The answer is not always a simple yes or no. While laser procedures remain highly effective for correcting certain refractive errors, ophthalmologists frequently take a different approach when evaluating patients over the age of 40–45.The reason lies in a natural age-related condition known as presbyopia, which gradually affects the eye’s ability to focus on near objects. Understanding how presbyopia develops—and how it differs from other vision problems—can help explain why treatment strategies for vision correction often change with age.How Vision Changes After the Age of 40The human eye contains a clear structure called the natural crystalline lens, located behind the iris. This lens works together with the cornea to focus incoming light onto the retina, allowing us to see clearly at various distances.In younger individuals, the lens is soft and flexible, which allows it to change shape quickly. This ability enables the eye to shift focus easily between distant objects and close-up tasks such as reading or using a smartphone.However, as part of the natural aging process, the lens gradually becomes less flexible and more rigid. This reduced ability to change shape limits the eye’s focusing capability for near objects. This condition is called presbyopia, and it usually begins to appear between the ages of 40 and 45.What Is Presbyopia?Presbyopia is one of the most common vision changes associated with aging. Unlike refractive errors such as myopia or astigmatism, presbyopia is not caused by the shape of the cornea but rather by the loss of accommodation in the natural lens. Common symptoms include: Difficulty reading small text The need to hold objects farther away to see clearly Eye strain during close work Increased dependence on reading glasses Difficulty focusing when switching between near and far objects Because these symptoms develop gradually, many individuals initially assume they simply need stronger glasses or better lighting. However, presbyopia is a structural change in the eye that cannot be reversed through glasses alone.Because these symptoms develop gradually, many individuals initially assume they simply need stronger glasses or better lighting. However, presbyopia is a structural change in the eye that cannot be reversed through glasses alone.What Laser Vision Correction Actually TreatsLaser vision correction procedures such as LASIK, SMILE, and LASEK are designed to correct refractive errors by reshaping the cornea, the transparent front surface of the eye.These procedures are highly effective for treating: Myopia (nearsightedness) Hyperopia (farsightedness) Astigmatism By altering the curvature of the cornea, the laser improves how light is focused onto the retina, resulting in clearer distance vision. However, laser surgery does not change the natural lens inside the eye. Because presbyopia is caused by reduced flexibility of this lens, laser vision correction cannot fully address the problem.Why Patients Over 45 May Still Need Reading GlassesFor patients who already have presbyopia, laser surgery may successfully correct distance vision, but it will not restore the eye’s ability to focus on nearby objects.In practical terms, this means a patient may achieve: Excellent distance vision after surgery,but Still require reading glasses for near tasks. For some individuals, this outcome may feel disappointing if their goal is to eliminate glasses completely. For this reason, ophthalmologists carefully evaluate the overall visual needs and expectations of patients over the age of 45 before recommending laser vision correction. Alternative Vision Correction Options After 45Because presbyopia originates from changes in the natural lens of the eye, many ophthalmologists recommend treatment options that address the lens itself rather than focusing solely on the cornea.One of the most commonly recommended procedures for patients over the age of 45 is Refractive Lens Exchange (RLE), a surgical technique that is very similar to modern cataract surgery.During this procedure, the eye’s natural lens is carefully removed and replaced with a clear artificial intraocular lens (IOL). This advanced artificial lens restores the eye’s focusing ability and provides stable visual correction. Today’s premium intraocular lenses are designed to improve vision across multiple distances, allowing many patients to significantly reduce their dependence on glasses in everyday life.ConclusionVision naturally changes as we age, and after the age of 40–45 many people begin to experience presbyopia, a condition caused by the gradual loss of flexibility in the eye’s natural lens. While laser vision correction procedures such as LASIK, SMILE, or LASEK are highly effective for correcting refractive errors, they do not address the age-related changes occurring inside the lens. For this reason, it is important to undergo a comprehensive eye examination to determine the most appropriate vision correction option based on your age, eye health, and visual needs. In many cases, modern solutions such as Refractive Lens Exchange (RLE) or advanced intraocular lenses may provide a more suitable long-term outcome for patients over 45.

At BGN Eye Clinic, every patient goes through a structured, safe, and fully guided journey from the first examination to post-surgery care. Here’s a simple summary of each step.STEP 1 — Comprehensive Eye ExaminationWe begin with a full diagnostic exam using premium ZEISS technology. Your cornea shape, cornea thickness, retina, optic nerve, dryness level, and overall eye health are scanned in detail. This step takes about 2–3 hours and builds the foundation for your customized treatment plan.   STEP 2 — Detailed Consultation & Q&AThe doctor reviews all your results clearly and explains what they mean. You can ask anything — recovery, pain, travel, daily life, and surgery expectations. The goal is to make sure you feel informed and confident.STEP 3 — Choosing the Right SurgeryBased on your scans, the doctor recommends the safest and most accurate procedure: • SMILE Pro • SMILE LASIK • LASEK • ICL You’ll understand why this method fits your eyes and what results to expect.STEP 4 — Preparation for SurgeryBefore entering the laser room: • Final measurements are checked • Gentle numbing drops are applied • The eye area is cleaned for safety • The team makes sure you’re relaxed and ready No needles, no injections — only comfortable eye drops.STEP 5 — 10-Minute SurgeryYou lie comfortably on the laser bed. The doctor guides you to follow a small light — no pain, just mild pressure. The entire procedure takes around 10 minutes, with only seconds of laser time per eye. Most patients say, “It was faster than expected!STEP 6 — Immediate Post-Op CareAfter surgery, the team checks your vision, applies protective drops, and explains all after-care instructions. You rest briefly, and most patients go home the same day.STEP 7 — Recovery & Follow-UpThe next day, you return for a check-up. Vision improves quickly, especially after SMILE Pro. The clinic continues to monitor your healing to ensure perfect, safe recovery.

LASIK vs. LASEK: A Professional Comparison for Patients Considering Laser Vision CorrectionLaser vision correction has become one of the most widely performed elective procedures worldwide. Among the available techniques, LASIK (Laser-Assisted In Situ Keratomileusis) and LASEK (Laser-Assisted Subepithelial Keratectomy) remain two established and reliable options.Although both procedures aim to correct refractive errors by reshaping the cornea, their surgical approach, recovery profile, and suitability for certain patients differ. Understanding these distinctions is essential for making an informed decision.1. Surgical Technique: Structural DifferencesLASIKLASIK involves the creation of a thin corneal flap using either a femtosecond laser or a microkeratome. The surgeon then reshapes the underlying stromal tissue with an excimer laser. After the laser application, the flap is repositioned.This technique preserves the outer surface but alters deeper corneal tissue.LASEKLASEK does not involve flap creation. Instead, the outer epithelial layer of the cornea is gently loosened and temporarily displaced. The excimer laser reshapes the surface of the cornea, and the epithelium is repositioned to regenerate naturally over several days. Because no flap is created, the structural integrity of the cornea remains more intact.2. Recovery ProfileRecovery experience is one of the most significant differences between the two procedures.LASIK Recovery Functional vision typically returns within 24–48 hours Minimal discomfort (often limited to several hours) Rapid return to work and daily activities Visual stabilization is generally fast, making LASIK attractive to patients seeking minimal downtime.LASEK Recovery Initial healing period of approximately 3–7 days Moderate discomfort during epithelial regeneration Gradual visual improvement over 1–2 weeks While the recovery is slower, final visual outcomes are comparable to LASIK once healing is complete.3. Pain and Postoperative ComfortLASIK patients typically experience mild irritation or foreign body sensation lasting a few hours.LASEK patients may experience more noticeable discomfort for 2–3 days, as the corneal surface heals. A protective contact lens is usually placed during this period to aid healing and reduce discomfort. Proper postoperative care significantly improves patient comfort in both procedures.4. Corneal Thickness and Structural ConsiderationsCorneal thickness is a critical factor in surgical planning. LASIK requires sufficient corneal thickness to safely create a flap and perform stromal reshaping. LASEK is often recommended for patients with thinner corneas because it does not involve flap creation or deep stromal cuts. Preoperative corneal mapping and pachymetry measurements are essential to determine candidacy.5. Dry Eye ConsiderationsTemporary dry eye symptoms can occur after any refractive surgery.LASIK may carry a slightly higher short-term risk due to corneal nerve disruption during flap creation. LASEK may preserve more surface nerves, potentially reducing early dry eye symptoms. However, long-term dry eye outcomes are generally comparable when patients are properly screened.6. Lifestyle and Occupational FactorsLASEK is often preferred in: Contact sports athletes Military personnel Individuals at risk of eye trauma Because no flap is present, there is no risk of flap displacement. LASIK remains highly suitable for individuals with low trauma risk who prioritize rapid visual recovery.7. Long-Term Visual OutcomesExtensive clinical data show that both LASIK and LASEK provide: High patient satisfaction rates Stable long-term refractive correction Comparable visual acuity outcomes once healing is complete The difference lies primarily in recovery dynamics and structural approach — not in final visual quality.Which Procedure Is More Appropriate?There is no universally “better” option.The appropriate procedure depends on: Corneal thickness and topography Degree of refractive error Tear film stability Lifestyle and occupation Individual healing response A comprehensive preoperative examination is mandatory to determine safety and suitability.Importance of Comprehensive Preoperative EvaluationA proper refractive surgery assessment should include: Corneal topography and tomography Pachymetry (corneal thickness measurement) Tear film analysis Retinal examination Refraction stability evaluation Only after reviewing these results can a surgeon recommend the safest and most effective option.ConclusionBoth LASIK and LASEK are well-established, safe, and effective laser vision correction procedures when performed on appropriately selected candidates.LASIK offers faster recovery and minimal downtime. LASEK offers structural advantages for thinner corneas and high-impact lifestyles. The key to success is not choosing the more popular procedure, but choosing the procedure most appropriate for your individual ocular condition.📍 BGN Eye Clinic – Lotte World Tower, SeoulIf you would like a comprehensive evaluation to determine whether LASIK or LASEK is more suitable for your eyes, our team will be happy to assist you.📞 Tel: +82 10-3435-5770(KakaoTalk & WhatsApp available)📧 Email: info@bgneyeclinic.com🌐 Website: www.bgneyeclinic.com📍 Address:Lotte World Tower, 11th Floor 300 Olympic Road, Songpa-g Seoul, Korea
