Wearing Color Contacts After SMILE LASIK: When Is It Safe?A Complete Golden-Time Guide to Wearing Lenses Before and After Vision Correction SurgeryDuring consultations, there is one concern patients often find difficult to give up: wearing cosmetic (color) contact lenses. Questions like “Can I still wear contact lenses after surgery?” are among the most frequently asked in our clinic.Today, we clearly outline the golden rules and medical reasons for wearing contact lenses before and after LASIK, LASEK, and SMILE LASIK.Wearing Lenses After SMILE LASIK Is Not Permanently BannedTo address the main question directly: wearing lenses after SMILE LASIK is not impossible forever. However, your eyes require absolute rest for at least 2 to 3 months, which is the essential timeframe needed for the corneal tissue to fully recover.Immediately following surgery, the surface of your cornea is in an exceptionally sensitive state. Wearing contact lenses during this delicate recovery phase can lead to the following side effects:1. Increased Risk of InfectionBacteria can more easily enter through microscopic wounds created during healing.2. Delayed RecoveryLenses restrict oxygen delivery to the cornea, slowing down the rate of cellular regeneration.3. Worsened Dry Eye SymptomsBecause the tear film remains unstable during early recovery, contact lenses can cause severe dryness and a harsh foreign-body sensation.Therefore, we strongly advise wearing contact lenses only after receiving confirmation from your eye care specialist during a follow-up checkup that your cornea and tear film have stabilized. Even then, usage should be restricted to short durations of 4 to 6 hours per day.The Pre-Surgery Rest Period Determines Your ResultsAn aspect many patients overlook is pre-operative care. To perform a precise vision correction, you must stop wearing contact lenses for a set period prior to your examination. This is due to a medical condition known as corneal warpage (corneal compression).Long-term lens wear temporarily alters the natural shape of your thin corneal surface. Conducting measurements under these conditions leads to inaccurate diagnostic data, directly affecting surgical accuracy. Please strictly adhere to the following guidelines:Required Discontinuation Period by Lens Type✔Soft Lenses: Minimum 7 days (1 week)✔Hard Lenses (RGP): Minimum 14 days (2 weeks)✔Dream Lenses (Orthokeratology): Minimum 1 month or longerAssuming “It’s just a short time, so it should be fine” and wearing lenses right before an exam risks basing your surgical plan on inaccurate corneal curvature data. Rigorous adherence to these timelines is critical for your safety.Soft Lenses vs. Hard Lenses: Which Choice Is Right for You?Patients also frequently ask whether soft or hard lenses are better before or after surgery. This is a medical determination based entirely on individual eye topography and health.Standard soft lenses offer high comfort but have lower oxygen permeability, making them prone to inducing dry eyes. Conversely, hard (RGP) lenses require an adaptation phase, but they provide superior oxygen flow and exceptional astigmatism correction, making them advantageous for individuals with high myopia or severe astigmatism.Rather than deciding based on personal lifestyle habits alone, the safest approach is to consult an eye care specialist based on comprehensive diagnostic test results.To ensure accurate diagnostic testing before surgery and a safe recovery afterward, give your eyes the rest they truly deserve.For your valuable vision, BGN Eye Clinic Jamsil Branch is committed to supporting you with precise evaluations and transparent consultations every step of the way.Was this content helpful?If you have questions about your specific contact lens restriction period or eligibility for surgery, feel free to reach out anytime.

This is BGN Eye Clinic at Jamsil Lotte Tower.SMILE Pro is the latest vision correction procedure developed based on the core principles of traditional SMILE LASIK. While utilizing the same underlying surgical method; the lenticule extraction technique, it offers significant advancements in equipment, laser speed, and precision calibration technology.At BGN Eye Clinic Jamsil, we perform procedures using the specialized SMILE Pro equipment, the VisuMax 800.How Does SMILE Pro Differ from Traditional SMILE LASIK?Compared to the VisuMax 500 used in traditional SMILE LASIK, SMILE Pro features enhanced laser delivery speed and advanced eye-tracking compensation technology. Rather than changing the surgical principle itself, it is most accurate to understand SMILE Pro as an upgraded version engineered for greater technical precision and speed.3 Core Technologies of SMILE Pro1. Faster Laser Delivery SpeedSMILE Pro significantly increases laser delivery speed compared to previous generation equipment. By reducing the time required to create the corneal lenticule, the eye fixation time is shortened, helping to alleviate physical and mental pressure during surgery. Faster surgery is not merely a matter of convenience; it also serves as a positive factor in minimizing the possibility of subtle eye movements during the procedure.2. Oculign® – Astigmatism Alignment PrecisionWhen lying down, a person's eyes can undergo subtle rotational shifts. Oculign® is an automated system that detects and compensates for these cyclotorsional movements. This feature plays a vital role in enhancing the accuracy of astigmatism correction. Because angular errors can significantly impact visual quality when astigmatism is present, this precision compensation technology serves as a cornerstone of the procedure.3. CentraLign® – Center Alignment TechnologyCentraLign® is a technology designed to align the center of the cornea with higher precision. It ensures that the central axis of laser delivery remains stable, effectively reducing potential surgical margins of error. This demonstrates that SMILE Pro has evolved not just to be a "fast surgery," but to significantly elevate alignment accuracy.Summary of Differences: SMILE Pro vs. SMILE LASIKFeatureSMILE LASIKSMILE ProEquipmentVisuMax 500VisuMax 800Laser SpeedStandard SpeedEnhanced Delivery SpeedAstigmatism CorrectionStandard CompensationOculign® Auto AlignmentCenter AlignmentStandard AlignmentCentraLign® Precision AlignmentSurgical PrincipleLenticule ExtractionIdentical (Lenticule Extraction)The key takeaway is that the fundamental surgical methodology remains the same.

When Only One Eye Is Red: Is It Just Fatigue? Causes & SolutionsEye Health Guide by BGN Eye Clinic Jamsil Lotte TowerHello, this is BGN Eye Clinic at Jamsil Lotte Tower.Have you ever promised yourself on a weekend, "I'm going to bed early tonight," only to find yourself binge-watching Netflix or scrolling through your smartphone until 3 AM? I recently had a similar experience. After staying up all night, I looked in the mirror before heading to work and noticed my eye was bloodshot. It was fun while watching, but like many of you, I instantly regretted it the next morning.Waking up to find only one eye noticeably red can be quite alarming. While ocular redness is a common symptom, its underlying causes range from simple fatigue and dry eye syndrome to burst blood vessels (subconjunctival hemorrhage) or early signs of serious eye conditions that require medical attention. Today, let’s walk through the potential causes of redness when it occurs in just one eye.Common Causes: Why Redness Occurs in One EyeAccumulated Fatigue and Dry Eye SyndromeThe most frequent culprits are general fatigue and dry eye syndrome caused by lack of hydration. Although dry eye typically affects both eyes, daily lifestyle habits often make one eye significantly drier and more irritated than the other.Daily Habits That Cause One Eye to Become Drier and Worse:Habitually rubbing one specific eye more often than the other.Having a reading lamp or computer monitor light shining directly from one side.Sitting where air conditioner or heater airflow blows directly onto one side of your face.Driving with air vents pointed exclusively toward one direction.Contact Lens Issues and ConjunctivitisSubtle differences in tear production or corneal curvature between eyes can lead to issues where "only the left eye becomes red" when wearing contact lenses. Furthermore, if foreign particles or allergens enter just one eye, it can trigger infectious or allergic conjunctivitis, causing localized redness. If accompanied by itching, tearing, or swelling, conjunctivitis should be strongly suspected.Real Patient Case: Redness Caused by Long-Distance DrivingA patient in his 40s recently visited our clinic stating, "My right eye is completely fine, but my left eye keeps developing broken blood vessels and redness." Upon detailed examination, the cause turned out to be his daily driving commute: sunlight continuously entered through his left window while cold air from the vent blew directly at the left side of his face.The Solution: UV Sunglasses and Vent AdjustmentBy wearing UV-blocking sunglasses while driving and redirecting the air vent downward, his redness improved noticeably within a few days. This case clearly illustrates how small environmental factors, like daily UV exposure and dry airflow, can significantly impact eye health.Warning Signs That Require Immediate Medical CareIf your redness is accompanied by any of the following symptoms rather than simple fatigue, do not delay. Visit an ophthalmologist promptly for precise examination and treatment:Persistent Redness: The redness does not subside after a week, even with rest and artificial tears.Severe Accompanying Symptoms: Accompanied by eye pain, extreme light sensitivity (photophobia), or sudden vision loss.Excessive Discharge: Thick, sticky discharge makes it difficult to open your eyes in the morning.Recurrent Broken Blood Vessels: Frequent subconjunctival hemorrhage requires evaluation for blood pressure or systemic conditions.Emergency Alert: Suspected Early Signs of GlaucomaIf severe redness in one eye occurs alongside intense headaches, ocular pain, nausea, vomiting, or blurred vision, it may indicate acute glaucoma. Seek immediate emergency care or visit an ophthalmologist, as delayed response can lead to permanent optic nerve damage.Frequently Asked Questions (FAQ)Q: Why do I wake up with redness in only one eye?A: This can be caused by nocturnal dry eye syndrome, where insufficient tears are produced during sleep. Alternatively, habits such as sleeping predominantly on one side or irritation from dust on your pillowcase causing localized allergic conjunctivitis could be affecting just one eye overnight.Q: My eye has been red for 3 days with discomfort and pain. What should I do?A: If redness persists for more than three days alongside pain, foreign body sensation, or light sensitivity, it is very likely more than simple fatigue. It could signal keratitis, uveitis, or another major ocular condition. Do not ignore it; visit an eye specialist immediately for a thorough evaluation and proper treatment.Final Words for Healthy VisionWhile eye redness is common, severe or recurring redness in a single eye should never be taken lightly. Once damaged, eyes are extremely delicate to restore to their original state. By detecting underlying conditions early through regular eye exams and making small improvements to daily habits, you can protect clear vision for a lifetime.The small care you take today will reward you with clear sight 10 to 20 years down the road. BGN Eye Clinic at Jamsil Lotte Tower will always be here to support your eye health with accurate and reliable information. Thank you.

SMILE Pro vs. SMILE: Differences & Benefits of Advanced Vision CorrectionBy Nurse Lee Ji-won | The Revolutionary 7-Second Laser of VisuMax 800Hello, this is BGN Eye Clinic at Lotte Tower, Jamsil.When a new smartphone is released, the first thing most people check is the specifications. "How much better is the camera this time? Does the battery last longer?" These subtle differences often drive our final choices. A remarkably similar dynamic occurs in ophthalmology.Recently, the question we hear most frequently from patients is, "What is the difference between SMILE Pro and traditional SMILE?" It is far more than just a name change. From shorter procedure times and enhanced precision to a more comfortable recovery process, the advancements are substantial. Today, based on real clinical consultation cases, I will break down why SMILE Pro is receiving so much global attention.How Does SMILE Pro Differ?SMILE Pro retains the core principles of traditional SMILE surgery while integrating state-of-the-art laser technology, representing the next evolutionary step in vision correction. While traditional SMILE was already renowned for its fast recovery, SMILE Pro advances this further through unprecedented laser speeds and minimized incision size.Laser Delivery Time ComparisonTraditional SMILE: Approx. 25 secondsAdvanced SMILE Pro: Under 10 seconds (Average 7 seconds)A difference of 15 seconds might seem minor on paper, but during an actual procedure, it dramatically reduces the tension of keeping the eye fixed and cuts corneal exposure time by more than half. Consequently, this minimizes the risk of infection and postoperative discomfort. In fact, the most common patient reaction immediately after surgery is, "Is it already over?"What Are the Key Advantages of a Faster Procedure?1. Reduced Eye Exposure Lowers Infection RiskEven in a sterile operating room environment, shorter exposure of the eye to ambient air directly correlates with lower risk. Because the laser application in SMILE Pro is completed in an average of 7 seconds, patient anxiety and physical strain are significantly diminished.2. Less Corneal Stress → Reduced Pain & DiscomfortReduced laser application time means less physical stress on the corneal tissue. Postoperative symptoms such as stinging or dryness are greatly reduced, allowing for a much smoother initial recovery phase.3. Swift Recovery → Rapid Return to Daily LifePatients undergoing SMILE Pro can resume routine activities such as reading, working on a computer, or attending classes as early as the next day. This offers a major advantage for busy working professionals and students with limited time off. Furthermore, for those who enjoy contact sports like basketball or soccer, SMILE Pro provides exceptional structural stability due to its micro-incision nature.Enhanced Precision in Surgical OutcomesThe dedicated platform for SMILE Pro, the VisuMax 800, features real-time eye-tracking technology. The laser dynamically tracks micro-movements of the pupil caused by breathing or heartbeat, delivering treatment with exceptional accuracy.This technology shows an even more distinct advantage in astigmatism correction. Even a 1-to-2-degree deviation in the astigmatic axis can compromise visual clarity; SMILE Pro utilizes advanced compensation algorithms to ensure stable, highly predictable results. Patient feedback often highlights this benefit: "Nighttime driving used to be uncomfortable due to my astigmatism, but now my vision is clear and effortless."Is the Safety Profile Proven?SMILE Pro is not an untested methodology, but an advanced upgrade built upon the internationally proven foundation of SMILE technology. The next-generation VisuMax 800 device has been refined using vast clinical datasets, establishing an exceptionally high standard of safety.Equally important as the technology itself is comprehensive pre-operative screening and structured post-operative care. A truly safe procedure relies on thorough assessments covering everything from corneal thickness to tear production levels.Who Is SMILE Pro Recommended For?✔ Busy Professionals & Students: Those requiring swift procedures and rapid recovery.✔ Active Individuals: Those seeking high resistance to physical impact and quick back-to-sport timelines.✔ Dry Eye Sufferers: Those wishing to minimize corneal nerve impact and reduce post-op dryness.✔ High Astigmatism Patients: Those seeking sharp, crisp vision through precise axis compensation.Frequently Asked Questions (FAQ)Q1. What if I blink during the procedure?Do not worry. The system tracks and compensates for micro-movements while an eyelid speculum gently keeps the eye open, preventing any complications from blinking.Q2. How soon can I exercise after surgery?Light walking is fine starting the next day. However, strenuous activities (swimming, ball sports) should be avoided for 2–3 weeks. Recovery varies individually, so please consult your surgeon during follow-up exams.Q3. How does it compare to traditional LASIK or LASEK?SMILE procedures feature a much smaller incision than LASIK or LASEK, leading to faster healing and higher structural resistance to physical impact. SMILE Pro elevates this further with enhanced speed and precision.ConclusionSMILE Pro seamlessly combines proven surgical principles with the precision of next-generation technology. Designed with patient comfort at its core, it frequently evokes comments like, "It was over faster than I expected," or "I can see clearly already."The most critical step remains identifying the treatment safest and best suited for your unique eye profile. Rather than hesitating, schedule a comprehensive examination to discover your optimal path to clear vision. BGN Eye Clinic is dedicated to supporting your journey toward healthy, sharp sight.

Is Wearing Contact Lenses for Long Hours Really Bad for Your Eyes?Insights & Advice from BGN Eye Clinic Jamsil"Is wearing contact lenses for long hours really that bad for your eyes?"Hello, this is BGN Eye Clinic Jamsil Branch.Today, we would like to talk about one of the most frequent questions we hear in our consultation room: "Is it okay to wear contact lenses for extended periods?" Honestly, it is a question we answer several times a day. It comes up most often from university students and young working professionals in their 20s and 30s who lead busy, fast-paced lives. Just today, a college student asked us the exact same thing, so let us break it down for you right here!A College Student's Concern: "Is It Okay to Wear Lenses for 15 Hours?"During our first consultation of the morning, a college student in her early 20s hesitantly shared her worry:"Optometrist, because of my major courses and endless assignments, I end up wearing contact lenses for more than 15 hours a day. My eyes feel okay right now... but will this really hurt my vision in the long run?"Looking at her already tired eyes, I shared this advice: "Just like our skin, our eyes need time to rest and breathe naturally."Ocular Changes and Side Effects from Daily Lens WearWhile most organs in our body receive oxygen through blood vessels, the transparent cornea has no blood vessels. Instead, it absorbs oxygen directly from the surrounding air. However, when you wear contact lenses every day especially for 15 hours at a time, the cornea's ability to absorb oxygen becomes gradually compromised.1. Rapid Increase in Eye FatigueWhen oxygen supply is insufficient, the cornea tires easily and swells. This is precisely why your eyes feel dry, gritty, and blurry by the evening.2. Bloodshot Eyes Surrounding the IrisTo compensate for the lack of oxygen, the eye attempts to supply oxygen by expanding surrounding blood vessels. This explains why fine red blood vessels become noticeably prominent on days you wear lenses for too long.3. Increased Ocular SensitivityWhen this cycle repeats, the eye's baseline resilience drops. As a result, you experience dryness much faster than before and your eyes become overly sensitive to tiny dust particles.Understanding this, the student nodded and said, "Ah, so that's why my eyes felt so red and uncomfortable every evening!"Essential Guidelines for Contact Lens WearersTip 1: Recommended Wear TimeThe ideal wear time for contact lenses is around 8 hours a day.If you must wear them longer, remove them for at least 1 to 2 hours during the day to let your eyes rest.Habitual all-day wear causes microscopic corneal damage that can lead to long-term complications.Tip 2: The Number One Habit to AvoidNever sleep or nap with your contact lenses on! People often think a quick nap is harmless, but sleeping in lenses drastically reduces oxygen supply while eyes are already drier under closed eyelids. With lenses covering the cornea, the tissue is virtually suffocated.Tip 3: How to Use Artificial TearsUse artificial tears 2 to 3 times a day as a baseline proactive care before feeling dryness is key.Preservative-free single-use drops are strongly recommended for contact lens wearers.Behind the Scenes in the Consultation RoomAfter listening to my detailed explanation, the student realized her symptoms were direct warning signs. Right after her eye examination, she removed her lenses, applied artificial tears, and promised, "I will definitely take break intervals from now on!" Moments like these, when patients decide to treasure their eye health, are the most rewarding for an optometrist.Real Case: The Risks of Prolonged Lens WearOne memorable case involved a female patient in her late 20s who habitually wore lenses for over 17 hours daily. What started as minor redness escalated to corneal epithelial scratches and a bacterial infection. Fortunately, early medical intervention prevented severe complications, but she was completely unable to wear contact lenses for a considerable period.Everyday Lifestyle Habits for Healthy EyesIn addition to proper lens habits, incorporating these daily practices supports long-term ocular wellness:Manage Digital Screen Time: Follow the 20-20-20 rule: every 20 minutes, look at an object 20 feet away for 20 seconds.Ensure Adequate Sleep: Lack of sleep lowers the natural recovery capacity of the ocular surface.Avoid Smoking: Smoking significantly increases the risk of dry eye syndrome and cataracts.Maintain Good Ocular Nutrition: Include essential nutrients such as Omega-3, Vitamin A, and Lutein in your diet.Key Takeaways TodaySummary:Limit daily contact lens wear to approximately 8 hours.If extended wear is unavoidable, always build in rest breaks without lenses.Never sleep while wearing contact lenses.Apply preservative-free artificial tears frequently throughout the day.Your eyes are irreplaceable. Please remember that small, careless habits formed today for short-term convenience can lead to lifelong discomfort. Taking care of your vision starts with simple, daily choices.

What Determines the Recovery Speed of SMILE Pro?The Secret Behind the 1.8mm Incision Explained by an Optometrist at BGN Eye ClinicHello! This is BGN Eye Clinic at Jamsil Lotte World Tower.Every morning when I open the clinic doors, the first device I turn on is our SMILE surgery equipment. As its crisp white light turns on with a gentle hum, I always feel that refreshing sense of anticipation: "Ready to give another patient clear vision today!"Lately, there is one question patients ask most frequently during consultations: "I heard that SMILE and SMILE Pro have different incision sizes. Does that really affect recovery time?" In fact, that small difference in the incision size is precisely the key advantage of SMILE Pro.SMILE vs. SMILE Pro: Starting with the Incision SizeLet us look at the numbers first. The incision size for traditional SMILE is approximately 2 to 4 mm, whereas for SMILE Pro, it is only about 1.8 to 2.0 mm. Looking at these numbers, you might wonder, "Is a difference of just 1 to 2 mm really that significant?" However, this minute difference is what truly determines your recovery speed and overall comfort.Thousands of microscopic corneal nerves, much thinner than a strand of human hair, are distributed across our cornea. These delicate nerves play a vital role in sensing irritation and maintaining healthy tear secretion. If these nerves are severed during surgery, temporary dryness or blurry vision can occur. By minimizing the incision length, nerve damage is significantly reduced, leading to a remarkably faster recovery.3 Core Strengths of SMILE Pro•Minimized Corneal Nerve Damage•Reduced Post-Operative Dryness•Pain-Free, Rapid RecoveryDuring consultations, we often hear comments like, "My friend who had LASIK years ago experienced stinging for days, but I felt virtually nothing." This distinct difference stems entirely from the incision size. A mere 1 to 2 mm holds tremendous significance for the human eye, a smaller incision means preserving more of your eye's natural healing capacity.Smaller Incisions, Faster Recovery: Real Differences You Can FeelBecause SMILE Pro utilizes a smaller incision, patients experience noticeable improvements in their post-operative recovery. When we see patients in the clinic, those who underwent SMILE Pro almost universally express how comfortable they feel. Their eyes stabilize within just one day, allowing them to return to their daily routines remarkably fast.Minimal Initial DiscomfortA smaller incision naturally causes far less irritation. Unlike traditional LASIK or LASEK, there is almost no stinging or scraping sensation against the eyelid when blinking. In fact, many patients express surprise, saying, "I almost forgot I even had surgery." Aside from being cautious with rubbing your eyes or washing your face, daily life remains virtually uninterrupted.Rapid Visual RecoveryWith a smaller incision, the corneal surface stabilizes much quicker. While traditional SMILE generally requires 2 to 3 days for vision to clarify, SMILE Pro patients frequently report crisp, sharp vision as early as the next day. This serves as a massive advantage for professionals who need immediate visual acuity for tasks like driving, lecturing, or working long hours on computer screens.Significantly Less DrynessDry eye symptoms directly impact daily comfort. Since SMILE Pro preserves most corneal nerves, natural tear production continues normally. Consequently, patients require far fewer artificial teardrops post-surgery. Within a week, most note, "My eyes feel so natural that I rarely need to apply drops anymore."How Technologically Can We Achieve Such a Micro-Incision?How is it possible to make such a tiny incision? The answer lies in technological evolution. SMILE Pro procedures do not rely on older platforms—they are performed using the next-generation Schwind ATOS laser system.Micro-Precision Controlled at the Micron LevelThis advanced equipment controls the depth and angle of the laser in increments of 1/1000th of a millimeter. By accurately calculating corneal curvature and thickness, it creates the shortest and most efficient incision line possible. While legacy equipment adapted incisions to match general eye shapes, SMILE Pro analyzes individual corneal topography first to custom-design the optimal incision line.Smarter Incisions Mean Faster HealingThe SMILE Pro system delivers a smooth, optimized incision pathway, helping the laser pass through the cornea cleanly in a single, continuous step. A smoother edge allows tissue to adhere and heal naturally at an accelerated rate. Much like a clean edge cut on glass reduces micro-cracks, this minimizes post-operative irritation and stabilizes vision much faster.What Patients Say Most OftenThe phrase I hear most during post-op checkups the day after SMILE Pro surgery is: "Doctor, it feels way more comfortable than I expected." Any slight initial haziness clears up within 24 hours, opening up to surprisingly crisp vision.Some patients even mention feeling surprised by the complete absence of pain. With minimal nerve stimulation, one patient shared, "I went straight to a cafe right after my procedure. I couldn't believe I had just undergone eye surgery!" This highlights just how swift recovery is and how effortlessly patients resume their normal routines.Compared to friends who had traditional procedures, many are amazed: "I don't need to put artificial tears in all day like others do!" This level of comfort occurs because intact corneal nerves maintain smooth, healthy tear secretion.Most SMILE Pro patients achieve stable vision by the next morning, returning immediately to work, driving, and studying. It effectively gifts your eyes the precious time they need to recover comfortably without disrupting your lifestyle.At a Glance: How Incision Size Impacts RecoveryCategorySMILESMILE ProIncision LengthApprox. 2.0 – 4.0 mmApprox. 1.8 – 2.0 mmPain / DiscomfortMild foreign body sensationVirtually NoneVision RecoveryTakes 2 – 3 DaysClear within 1 DayDrynessPresent (Temporary)Very LowReturn to Daily LifeAfter 2 – 3 DaysNext Day PossibleVision StabilizationApprox. 1 – 2 WeeksStabilizes in 3 – 5 DaysIn ClosingSMILE Pro isn't just about "reducing incision length"—it is an advanced treatment engineered to protect your eye's natural healing abilities.

LASIK Side Effects: How Common Are They Really?Actual Incidence Rates and Prevention Methods Direct from the Surgical TeamWarm greetings from BGN Eye Clinic, located in the Lotte World Tower, Jamsil.Our surgical team meets countless patients in the operating room every day. To help ease their nerves, we often spend time answering brief questions. Recently, the single most frequent question we receive is about the potential side effects of LASIK.Many patients preparing for LASIK arrive with anxiety after reading negative reviews online. LASIK is one of the most established vision correction procedures, with decades of clinical experience and countless successful outcomes reported worldwide. However, because negative experiences are also easily accessible, it is entirely natural to feel curious and concerned.In today’s article, our surgical team will candidly break down the types of LASIK side effects, their actual occurrence rates, and effective prevention strategies.The Top 3 Concerns Most Patients HaveWhenever we chat with patients prior to surgery, three common concerns always come up.1. Dry Eye SyndromeRight after surgery, some patients experience stiffness or a gritty sensation in their eyes. Since many office professionals spend long hours in front of screens and may already suffer from pre-existing dry eyes, they tend to be especially sensitive to this. However, in the majority of cases, dry eye symptoms gradually improve as the eyes heal.2. Light Halos and GlareThis refers to the scattering of light around streetlamps or headlights at night. Drivers ask about this most frequently. While this phenomenon appears temporarily in the early stage, it naturally subsides as your brain adapts to your newly corrected vision. To ensure safety during the initial recovery phase, we advise refraining from night driving.3. Regression of Vision"Will I have to wear glasses again in a few years?" is another question we hear all the time. While minor visual shifts can happen depending on lifestyle habits or individual physiology, returning to a state where surgery becomes meaningless is exceptionally rare. Simply keeping up with your regular check-ups will help maintain comfortable, clear vision.QuotePrevention Matters Far More Than the Incidence RateOur surgical team always emphasizes that pre- and post-operative care is the absolute key. The reason we conduct over 10 precision examinations prior to surgery is precisely to eliminate side effects in advance.Precision analysis of corneal thickness and shapeMeasurement of pupil size and tear secretion levelsEvaluation of corneal nerve distribution and retinal healthThis thorough examination data serves as the single most reliable first step in minimizing potential complications.Essential Post-Operative Care RulesProper daily care following surgery is the cornerstone of effective prevention. Please keep in mind these 4 fundamental guidelines always stressed by our team:Never Miss Scheduled Check-ups: Even if your eyes feel completely fine, please visit the clinic according to your schedule. Having your attending surgeon directly verify your recovery progress is crucial.Make Eye Drops a Habit: Prescribed artificial tears are not merely temporary relief; they are a vital component of your healing process. For those working long hours with computer screens, use them regularly at least 4 times a day.Refrain from Rubbing Your Eyes: A healing cornea is sensitive even to minimal friction. Never rub your eyes to prevent corneal displacement or injury. Take this opportunity to eliminate habits that negatively impact your eye health.Prioritize Rest and Hydration: The eye’s ability to recover is directly tied to your overall body condition. Simply avoiding overwork and getting adequate sleep will noticeably accelerate your recovery pace.At BGN Eye Clinic Jamsil, we are dedicated to delivering results that satisfy every patient, spanning from initial examination to consultation, surgery, and post-operative management. Our board-certified ophthalmologists take full responsibility for the entire process, and our surgical team stays focused every second by your side, so you can trust us with complete peace of mind.Do not struggle with worries about LASIK side effects alone.

LASIK vs. SMILE LASIK: Essential Selection Points for Dry Eye PatientsBGN Eye Clinic | Lotte World Tower Main BranchHello, this is BGN Eye Clinic, located at the Lotte Tower main branch.Every time I visit a cafe, I find myself stuck in the same exact routine.Looking at the menu, I hesitate for quite a while, wondering, "Should I go with an iced Americano today, or get a sweet latte?"A refreshing iced Americano is crisp and clean, but a latte has its own smooth, comforting appeal, making it so hard to choose.I often end up lingering until the barista kindly asks, "May I take your order?" before finally making up my mind.Moments like these make me realize how much thought goes into even the smallest choices.In fact, a remarkably similar scene unfolds frequently right here in our consultation room.Patients often sit down for an in-depth conversation with us, only to ask one final question at the very end:"Doctor, would it be better for me to get LASIK or SMILE LASIK?"Because the names of both procedures sound so similar, it is easy to get confused.It is completely natural to hesitate when each option carries its own distinct advantages.Just as iced Americanos and lattes appeal to different tastes, LASIK and SMILE LASIK suit different people depending on their individual eye conditions and everyday habits.That is why today, I would like to break down the differences between LASIK and SMILE LASIK, the question I hear most often in our clinic, just like recommending your next favorite drink at a cafe.LASIK: A Familiar Vision Correction ProcedureThe core concept of LASIK lies in "correcting vision by gently lifting a corneal flap."Specifically, an extremely thin flap is created on the cornea, and the corneal stroma beneath it is reshaped using a laser.Once the flap is repositioned back in place, the procedure is complete.Having been performed globally for several decades, LASIK benefits from a long track record, proven stability, and extensive clinical expertise.Furthermore, because vision often improves dramatically immediately after surgery, recovery is remarkably fast, so fast that many patients share reviews like, "I had surgery today and went straight to work tomorrow."However, LASIK does have its drawbacks.Because the flap structure is extremely thin, it can be vulnerable if subjected to significant external impact.Additionally, since a relatively higher number of corneal nerves are severed during the process, there is a higher likelihood of experiencing post-operative dry eye syndrome.Therefore, if you lead a highly active lifestyle or already suffer from dry eyes, considering an alternative procedure may offer a much more comfortable long-term experience.SMILE LASIK: An Advanced Step ForwardAs the name suggests, SMILE LASIK stands for "Small Incision Lenticule Extraction": a technique that corrects vision through a minimal incision.Instead of creating a large flap on the cornea, a laser shapes a thin, disc-like piece of tissue inside the cornea, which is then removed through a tiny opening.Through this process, the shape of the cornea is corrected, restoring sharp vision.It is much easier to picture it as making a micro-hole rather than opening a large flap.The advantages of SMILE LASIK are exceptionally clear.Because the cornea is not broadly cut, the overall corneal structure remains significantly more stable and resistant to external impacts.Furthermore, the smaller incision results in minimal nerve damage.Consequently, post-operative dry eyes are far less common, allowing for a much smoother transition back to daily life.With virtually no pain or foreign-body sensation, patient satisfaction rates are remarkably high.Of course, there are some considerations.Since advanced laser equipment is required, the cost tends to be somewhat higher, and the treatable refractive range can be slightly more limited compared to traditional LASIK.In particular, individuals with extreme high myopia may find traditional LASIK to be a more suitable option depending on their specific measurements.LASIK vs. SMILE LASIK ComparisonCategoryLASIKSMILE LASIKSurgical MethodCreates a corneal flap, then reshapes the

aligns better with your personal needs before your consultation!The Story of Patient A: Hesitating Due to Dry Eye SyndromePatient A, an office worker in their 40s who recently visited our consultation room, shared their worries right from the start."Doctor, I heard that LASIK makes dry eyes much worse... To be honest, that really worries me."Having struggled with severe dry eye syndrome for a long time, Patient A relied heavily on artificial tears every day.Working in front of a computer screen all day left their eyes feeling gritty, and by the afternoon, severe redness would force them to rub their eyes repeatedly.Glasses were uncomfortable and contact lenses could no longer be worn for extended periods, leading them to consider vision correction surgery.However, the fear of "What if my dry eyes become unbearable after surgery?" kept them from taking action.The Connection Between LASIK and Dry EyesI first explained the procedural characteristics of LASIK to Patient A."LASIK involves creating a flap on the cornea, which inevitably cuts through a significant number of corneal nerve fibers.While those nerves heal, tear secretion can temporarily decrease, which may exacerbate symptoms if you already suffer from dry eyes."In other words, while LASIK itself is not inherently dangerous, extra caution is required for patients with pre-existing dry eye conditions.SMILE LASIK for Those Concerned About Dry EyesNext, I explained the key advantages of SMILE LASIK."SMILE LASIK utilizes a significantly smaller incision area compared to traditional LASIK.Because nerve damage in the cornea is kept to an absolute minimum, the risk of developing post-operative dry eye syndrome is substantially reduced.Therefore, for patients who already experience dry eye symptoms, SMILE LASIK often serves as a far more suitable solution."Upon hearing this explanation, Patient A’s expression brightened noticeable.The tension melted away into a gentle smile as they said,"Ah, I see! In that case, choosing SMILE LASIK makes complete sense for me.I was almost ready to give up on surgery altogether because of my dry eyes, but now my mind is completely at ease."Key Patient Decision FactorsThe question we receive most frequently during consultations is:"Is LASIK better, or is SMILE LASIK better?"However, there is no single "right" answer.The procedure that is best suited for you varies depending on your individual eye conditions, lifestyle habits, and personal expectations.Here is a quick reference guide based on common scenarios:(Please use this as a general guideline only! Comprehensive clinical testing is essential to confirm the exact fit for your eyes.)If you lead an active lifestyle or engage in intense sports → SMILE LASIKBecause LASIK involves a corneal flap, severe physical impact can potentially affect it. If you enjoy contact sports like soccer, basketball, or martial arts where physical collisions can happen, SMILE LASIK’s micro-incision provides greater structural security.If you frequently experience gritty, severely dry eyes → SMILE LASIKSince LASIK severs a higher proportion of corneal nerves, it can heighten dryness. SMILE LASIK minimizes nerve disruption, significantly lightening the burden of dry eye symptoms. This is particularly advantageous for office workers spent in front of screens or those with pre-existing dryness.If you have high prescriptions or extreme myopia → Consider LASIKSMILE LASIK has a more defined range of corrective power. In contrast, LASIK can accommodate a relatively broader range of refractive errors. Thus, for those with severe high myopia, traditional LASIK might be recommended depending on clinical measurements.If you require rapid vision recovery → LASIKLASIK patients often experience noticeably sharp vision almost immediately after the procedure. Those facing important upcoming exams or tight schedules who want the fastest visual onset often lean toward LASIK. While SMILE LASIK recovery is also exceptionally fast, the initial perceptual difference is usually about one day.LASEK vs. ICL (Phakic IOL) ComparisonCategoryLASEKICL (Implantable Collamer Lens)Surgical MethodRemoves corneal epithelium, reshapes with laser, and applies a protective lens.Inserts a specialized lens behind the iris (in front of the crystalline lens) via micro-incision.Incision SizeComplete removal of epithelial layer (no flap)Approx. 3mm micro-incisionRecovery SpeedSlow → Takes 2–4 weeks for full visual recoveryFast → Usually restores vision within 1–2 daysPain & DiscomfortPain and foreign-body sensation for 3–4 days post-surgeryMinimal to no painImpact ResistanceHigh impact resistance due to no flap creationPreserves corneal structure → Highly stableDry Eye RiskModerate potentialVirtually noneCorrection RangeSuitable for high myopia, but limited by corneal thicknessSuitable for extreme myopia (-15D+) or thin corneasCostRelatively affordableHighest tier (includes surgery + customized lens cost)ReversibilityLimited depending on remaining corneal tissueReversible (lens can be replaced or removed if needed)For those curious about options beyond LASIK and SMILE LASIK, here is a quick summary of LASEK and ICL (Lens Implantation):In Summary:LASEK is "affordable and impact-resistant, but involves longer recovery and temporary pain."ICL is "fast and comfortable, but higher in cost and involves implanting an artificial lens that requires long-term care."The ultimate takeaway: Precise medical examinations are essential.The points listed above serve as general reference criteria. Factors like corneal thickness, curvature, prescription strength, and pupil size differ from person to person. Therefore, determining which procedure is truly right for you requires an in-depth clinical assessment.There is no absolute rule stating that "LASIK is unconditionally best" or "SMILE LASIK is always safer." The smartest and safest choice is to select the method that uniquely fits your eyes after a thorough consultation with an eye care specialist.Both LASIK and SMILE LASIK are globally recognized, time-tested vision correction surgeries chosen by millions of patients around the world.The key is simply finding the method that suits your eyes best.Because your eyes are something you rely on for a lifetime, choosing a procedure based solely on word-of-mouth is not enough. Taking the time to undergo professional diagnostic testing is your safest route.If you are looking for comfortable vision and a safe surgical experience, we strongly encourage you to schedule a consultation with a specialist.We wish you a clear and healthy day ahead!This has been BGN Eye Clinic at Lotte Tower main branch.
