Who is LASIK Really For? Personalized Guide by Corneal Thickness and LifestylePrecision Analysis by BGN Eye Clinic Optometrists for Safe Vision CorrectionHello, this is BGN Eye Clinic at Jamsil Lotte Tower. Every day, I encounter countless eyes in my clinic. Among all the questions I receive, these are by far the most common:"Doctor, is LASIK better for me, or LASEK?""My eyes are quite sensitive. Is it really okay for me to undergo surgery?"To be honest, I used to wear glasses for a long time myself. Whenever my glasses fogged up while wearing a mask, or my eyes felt too dry to wear contact lenses for long hours, I found myself thinking, 'Should I just get LASIK?' It is a completely natural process that almost everyone considers at least once.That is why I would like to walk you through who is truly a good candidate for LASIK, and how recommendations vary depending on corneal thickness and lifestyle. I will share the real concerns of patients I meet in the consultation room, along with practical, in-depth advice.Let's Start with the Basics: How Does LASIK Work?Many patients ask in the consultation room, "What exactly is LASIK surgery?" Simply put, LASIK is a procedure where a very thin flap is created on the cornea, and the underlying tissue is reshaped with a laser. The cornea, located at the front of the eye, acts like a camera lens. The procedure adjusts the refractive power of this lens so light focuses accurately.The greatest advantage of LASIK is its rapid recovery. While you may feel slight discomfort immediately after surgery, there is virtually no pain, and by the next day, most patients remark that "the world looks completely different." Therefore, LASIK is particularly suitable for office workers and students who spend long hours in front of monitors, or anyone needing a quick return to their daily routine.Fundamental Criteria for LASIK CandidacyLASIK is not a one-size-fits-all procedure. During consultations, the primary question we evaluate is: "Are your eyes healthy and suitable enough to undergo LASIK safely?" When determining eligibility, three key criteria are evaluated:Sufficient Corneal Thickness: LASIK creates a flap and reshapes the tissue underneath with a laser. Therefore, a safe residual corneal thickness must remain after the procedure. Generally, a total corneal thickness of 520 μm or greater provides a comfortable safety margin.Stable Corneal Shape: If the corneal curvature is irregular or shows signs of keratoconus (an abnormal bulging of the cornea), alternative procedures such as SMILE Pro or LASEK are much safer options. This is why a preoperative corneal topography examination is essential.Absence of Severe Dry Eye or Inflammation: LASIK can cause temporary dry eye symptoms immediately post-surgery. We perform tear film and lipid layer analyses (LipiView) before surgery to ensure the ocular surface is stable. If necessary, we treat any underlying conditions first before proceeding with surgery.Surgical Decision Guide Based on Corneal ThicknessCorneal thickness serves as the baseline for choosing the right vision correction method. It determines which procedure, LASIK, LASEK, or SMILE Pro, is the safest choice for your eyes.Thick Cornea (520 μm or greater): LASIK is the most ideal option. Even after creating a flap, sufficient residual corneal thickness remains. It offers a wide correction range and virtually painless, ultra-fast recovery.Average Corneal Thickness (Around 500 μm): SMILE Pro is most frequently recommended in this range. Because no flap is created, corneal nerve damage is minimized, and structural integrity is well preserved, resulting in minimal dryness and stable recovery.Thin Cornea (480 μm or lower): LASEK is the safest choice. It preserves as much corneal tissue as possible, though the recovery period is slightly longer and initial discomfort or foreign body sensation may occur.Corneal Thickness   Recommended Surgery   Key FeaturesRecovery Speed520 μm or greaterLASIKSufficient margin for flap creation, wide correction rangeUltra-fast (1–2 days)Around 500 μmSMILE ProMinimal incision, minimal dry eye symptoms                          Fast (2–3 days)480 μm or lowerLASEKTissue-preserving, safe for thin corneasGradual (5–7 days)Matching LASIK to Your Profession and LifestyleChoosing a vision correction method goes beyond your current prescription; your daily lifestyle and occupation must also be taken into account.Office & IT Professionals: If you spend long hours looking at screens, managing dry eye symptoms is crucial. Provided you combine adequate use of artificial tears with regular rest, LASIK is a highly suitable choice.Athletes & Outdoor Enthusiasts: For those involved in sports with a risk of physical impact, such as soccer or basketball, SMILE Pro is safer than flap-based LASIK, as it maintains superior structural stability.Detail-Oriented Professionals (Designers, Artisans, etc.): If precise visual focus is required, we design the optimal procedure by evaluating contrast sensitivity and night vision test results alongside basic metrics.Who Is Ideal for LASIK vs. Who Should Avoid ItIdeal Candidates for LASIKIndividuals with sufficient corneal thickness and a stable corneal structureIndividuals desiring rapid recovery or a quick return to workIndividuals whose daily routines do not involve frequent exposure to heavy dust or intense UV raysWho Should Consider AlternativesIndividuals with thin corneas or irregular corneal protrusionIndividuals suffering from chronic dry eye syndrome or active ocular inflammationIndividuals who frequently rub their eyes or are at high risk of physical facial impact"Rather than asking whether LASIK is a good procedure, the first step is verifying whether your eyes are ready for LASIK. Prioritizing safety standards and your unique ocular health over cost or trends is always the smartest choice."Are your eyes suitable for LASIK?

Is Corneal Cross-linking Mandatory with SMILE Surgery? Efficacy and NecessityPrecision Solutions by BGN Eye Clinic for Long-Term Safe Vision ImprovementIf you are a college student or a young professional preparing for vision correction surgery, you likely have questions about the additional care procedures recommended during consultations, in addition to choosing the surgery technique itself.Particularly during SMILE surgery consultations, questions like these naturally arise:"Is corneal cross-linking really necessary?""Why is there an additional cost for corneal cross-linking?"In this article, we will explain why corneal cross-linking is recommended alongside SMILE surgery, when it should be considered, and how to approach the costs associated with it.1. Why Is Corneal Cross-linking Recommended During Consultations?After vision correction surgery, a thinned cornea can potentially lead to side effects such as keratoconus, corneal ectasia, or myopic regression.Therefore, corneal cross-linking is selectively recommended as a supportive care procedure to help maintain clear vision over the long term. This procedure strengthens the collagen matrix that forms the structural foundation of the cornea, thereby reducing the physical strain on the eye following surgery.Originally developed to halt the progression of keratoconus, cross-linking is now frequently presented as an advanced corneal management option in conjunction with SMILE surgery.2. How Is Corneal Cross-linking Performed?Corneal cross-linking performed with SMILE surgery follows a clear, two-step process:Riboflavin Instillation: A vitamin B2 (riboflavin) solution is repeatedly applied to the eye, allowing it to fully absorb into the corneal tissue.UV-A Irradiation: Ultraviolet-A (UV-A) light at a specific wavelength is directed onto the cornea. This triggers a reaction that forms cross-links between collagen fibers, enhancing the structural stability of the cornea.3. When Should Corneal Cross-linking Be Considered?Corneal cross-linking is not applied identically to every candidate undergoing SMILE surgery. Based on medical evaluation, it may be recommended in the following cases:When the baseline corneal thickness is relatively thinWhen a large amount of tissue must be ablated due to high myopia or severe astigmatismWhen daily life involves heavy screen use or intense eye strainWhen long-term corneal stability requires additional reinforcementThe recommendation varies depending on individual ocular characteristics and daily lifestyle factors.4. Is Corneal Cross-linking Really Necessary?One of the most frequent questions during consultations is, "Is cross-linking mandatory?"The short answer is no; corneal cross-linking is not mandatory for everyone. However, it serves as a valuable option when structural considerations or surgical designs suggest that additional stability would be beneficial.Rather than viewing it as a universal requirement, it should be understood as a customized management choice evaluated according to your specific eye profile.5. Why Is There a Price Difference for Cross-linking?Many patients feel hesitant due to the additional cost of corneal cross-linking. The pricing reflects specialized equipment usage, extended procedure duration, and meticulous post-procedure care.However, rather than focusing solely on cost, it is crucial to discuss your corneal health thoroughly with your medical provider to determine whether cross-linking will offer tangible benefits for your specific situation.6. Criteria That Matter More Than CostCorneal cross-linking is better understood as a personalized care option tailored to your eyes and lifestyle, rather than an essential upgrade.If you find yourself wondering whether cross-linking is necessary or if the cost is justified, the best approach is to undergo a comprehensive examination and consult with a specialist to evaluate your options objectively.Who May Benefit from Corneal Cross-linking?Individuals concerned about high tissue ablation volumeIndividuals worried about potential side effects like myopic regressionIndividuals seeking extra assurance for long-term ocular stabilityFor those with these considerations, corneal cross-linking offers a reliable protective option.ConclusionWith SMILE surgery, proper recovery and post-operative care are just as important as the procedure itself. Rather than making a decision based solely on recommendations or costs, evaluate whether cross-linking aligns with your eye health needs.BGN Eye Clinic at Jamsil Lotte Tower provides thorough diagnostic evaluations and consultations to guide you toward safe and stable visual recovery.Curious about your personalized vision correction plan?BGN Eye Clinic supports your journey toward lasting visual clarity.

SMILE LASIK for High Myopia: Precise Corneal Design and Safety CriteriaPre-Surgery Essentials: Ocular Structure Analysis and Residual Corneal Thickness GuidelinesDr. Min-kyung KimOphthalmologist | BGN Eye Clinic JamsilQ. "I have high myopia with a very strong prescription. Is it safe for me to undergo SMILE LASIK? I am worried that my cornea might become too thin or that I might experience severe side effects."Hello, I am Dr. Min-kyung Kim, an ophthalmologist at BGN Eye Clinic Jamsil.Patients with severe myopia often rely heavily on strong glasses for everyday life and long for visual freedom. At the same time, because higher prescriptions require removing a larger volume of corneal tissue, concerns regarding potential side effects are naturally heightened. Based on real questions gathered during patient consultations, I would like to explain the essential safety criteria needed to make an informed and confident choice.Definition of High Myopia and Ocular Structural VulnerabilitiesIn clinical ophthalmology, high myopia is defined as a refractive error of -6.00D (diopters) or worse, while conditions exceeding -9.00D are categorized as extreme myopia. High myopia involves more than just a strong prescription; it is accompanied by structural changes where the axial length (the front-to-back length of the eye) stretches significantly compared to a normal eye.Classification            Diopter RangeStructural Characteristics & Risk ProfileMild Myopia           -0.25D to -3.00D      Standard myopia with minimal structural alteration of the eye.Moderate Myopia           -3.00D to -6.00DStage where the axial length begins to elongate slightly.High Myopia           -6.00D to -9.00DSignificant elongation of axial length, resulting in thinner ocular walls.Extreme Myopia            Below -9.00DRapidly elevated risk for retinal degeneration, tears, detachment, and glaucoma.As the eye stretches forward and backward, internal structures such as the retina and optic nerve tissue become taut and thin, similar to an overinflated balloon. Consequently, the risks for peripheral retinal degeneration, retinal tears, retinal detachment, and glaucoma become substantially higher than in eyes with normal vision.Therefore, when designing vision correction procedures for high myopia, surgeons must evaluate both the refractive error and the structural vulnerabilities of the inner eye multidimensionally.LASIK vs. LASEK vs. SMILE LASIK for High MyopiaTraditional LASIK for high myopia creates a corneal flap approximately 100–120 µm thick, folds it back to reshape the inner tissue, and reposition it. Because this technique requires a wide corneal incision, maintaining structural stability in eyes with high myopia can be challenging. On the other hand, LASEK gently removes the outer epithelial layer. While it avoids flap-related complications, it involves a longer recovery period and postoperative discomfort.SMILE LASIK addresses these limitations by utilizing a femtosecond laser that passes through the corneal surface to separate a precise piece of stromal tissue inside the cornea. Because the separated tissue fragment (lenticule) is extracted through a tiny 2mm micro-incision, the structural integrity and tensile strength of the corneal surface are preserved, making it an ideal option for safe vision recovery in high myopia patients.3 Core Safety Metrics for High Myopia SMILE LASIK1. Strict Adherence to Residual Corneal Thickness Guidelines: To prevent corneal ectasia (keratoconus), a condition where the weakened cornea bulges under intraocular pressure, maintaining a safe post-surgery residual corneal thickness of at least 380 µm is the top structural priority.2. Precise Visual Axis and Astigmatism Alignment: Patients with high myopia frequently present with accompanying astigmatism. If the visual axis (refractive center) and the astigmatism axis are slightly misaligned during correction, post-operative night glare and halos can increase. Precise alignment techniques during surgery are imperative.3. Healing Control to Prevent Myopic Regression: When large amounts of tissue are reshaped, natural cellular healing responses may cause the tissue to regrow slightly, leading to myopic regression. To prevent this, corneal collagen cross-linking (corneal strengthening) may be performed concurrently when necessary.The Evolution: SMILE LASIK vs. SMILE ProRecent medical advancements introduced the SMILE Pro system using the ultra-fast VisuMax 800 laser, delivering greater accuracy and stability during corneal correction for high myopia patients.1. Ultra-Fast VisuMax 800 Laser Delivery: SMILE Pro operates at significantly higher speeds, creating the refractive lenticule in just 7 to 9 seconds. Reducing laser exposure time dramatically lowers the risk of suction loss caused by microscopic eye movements or patient tension.2. OcuLign Digital Axis Alignment System: The OcuLign system automatically compensates for cyclotorsion (eye rotation when lying down) and aligns the line of sight in real time. This ensures accurate correction of complex astigmatism axes associated with high myopia, minimizing blur and residual refractive errors.📌 Note: Suitable treatment plans vary based on individual corneal thickness and refractive profiles identified during clinical evaluation.Comprehensive Diagnostic Standards at BGN Eye Clinic JamsilAchieving long-term satisfaction in high myopia correction requires adjusting for the subtle curvature and structural nuances of each eye. While advanced laser technology is critical, the surgeon's clinical expertise and rigorous multidimensional diagnostic screening are equally vital.BGN Eye Clinic Jamsil utilizes advanced diagnostic protocols including anterior/posterior corneal topography, corneal elasticity testing, high-resolution optic nerve analysis (OCT), and AI-driven predictive modeling to craft personalized vision correction plans.We promise to recommend only the safest, data-driven treatments for your eyes.

What Is Color Vision Deficiency? Causes, Types, and Management | BGN Eye Clinic Lotte TowerHow Our Eyes Perceive Color and Solutions for Color Vision DeficiencyHello, I am Dr. Se Kwang Park, Chief Ophthalmologist at BGN Eye Clinic Jamsil Lotte Tower.Today, I would like to share insightful information for those experiencing color vision deficiency.While I usually cover topics related to vision correction (LASIK, LASEK, SMILE, SMILE Pro, ICL) or presbyopia and cataracts, today I want to address the topic of color vision deficiency.The process of perceiving color is far more intricate than most people realize. For instance, when we look at a red apple, we naturally recognize it as "red." However, this is the complex result of light interaction, photoreceptor cells, and brain processing.In this post, I will guide you through how we see color, what color vision deficiency is, the challenges faced by those affected, and the current methods available to assist them.The Principle of Color Perception – The Relationship Between Light and ColorTo understand color, we must first understand light. When white light passes through a prism, it separates into seven colors: red, orange, yellow, green, blue, indigo, and violet. This spectrum constitutes the visible light spectrum that our eyes can detect.Objects absorb certain wavelengths of light and reflect others. For example, a red apple reflects red wavelengths while absorbing the rest, leading our vision to perceive the object as red.How Do Our Eyes Perceive Color?Inside our eyes, specialized cells known as photoreceptor cells detect light. These cells are divided into two main categories:Cone Cells (Cones): Responsible for detecting color.Rod Cells (Rods): Responsible for detecting brightness and contrast in low light.Cone cells play the central role in color perception. They are specialized into three types, each sensitive to specific wavelengths:L-Cones (Red Cones): Detect red light.M-Cones (Green Cones): Detect green light.S-Cones (Blue Cones): Detect blue light.These three types of cones work in unison to generate the broad spectrum of colors we perceive—a principle similar to the RGB color model used in digital displays.What Is Color Vision Deficiency (CVD)?For normal color vision, all three types of cone cells must function properly. However, when specific cone cells are missing or reduced in function due to genetic factors, aging, or underlying conditions, Color Vision Deficiency (CVD) occurs.Primary Causes of Color Vision DeficiencyGenetics: Inherited traits linked to the X chromosome, making the condition significantly more common in men.Aging: Natural degradation of cone cell function over time.Ocular Conditions: Diseases such as glaucoma or macular degeneration can impair color perception.Medication Side Effects: Certain medications, including specific antibiotics or antidepressants, may temporarily alter color vision.Types of Color Vision DeficiencyRed-Green Color Vision Deficiency: The most common form, causing difficulty in distinguishing between red and green shades.Blue-Yellow Color Vision Deficiency: A rarer form where distinguishing blue from yellow is difficult.Achromatopsia (Total Color Blindness): A very rare condition where individuals cannot perceive color at all, seeing only shades of grey.How Can Color Vision Deficiency Be Managed?While a definitive cure for inherited color vision deficiency does not currently exist, several management strategies and corrective tools are available to improve color discrimination.1. Color Corrective Eyewear and Contact LensesSpecially designed lenses filter specific light wavelengths, enhancing the contrast between color spectrums and making it easier to distinguish between overlapping shades.2. Digital Accessibility FeaturesModern operating systems, including iOS and Android, feature color accessibility modes that adjust screen contrast and color profiles to assist users with CVD.3. Emerging Gene Therapy ResearchAdvances in gene therapy show potential for restoring missing photo-pigments. While currently in experimental stages, future developments may provide curative approaches.4. Practical Tips for Daily LifeUtilize symbols (▲●■) or textual labels alongside color cues for clarity.Use mobile filter apps that identify colors in real-time.Communicate your vision characteristics openly with family and colleagues to adapt work and home environments.Understanding Your VisionThe human mechanism of seeing color involves a sophisticated sync between light, retinal cone cells, the optic nerve, and the brain. While living with color vision deficiency presents unique challenges, modern supportive tools offer substantial assistance.If you suspect you have color vision deficiency or wish to evaluate your visual health, we recommend scheduling a comprehensive clinical evaluation with an ophthalmologist.Interested in an Eye Examination or Consultation?Schedule an Appointment at BGN Eye Clinic

Does LASEK Hurt a Lot?Understanding LASEK Pain and Recovery"Does LASEK hurt a lot?"This is the very first question people ask when considering LASEK surgery.The truth is, LASEK pain does exist. However, what really matters is how severe the pain is, how many days it lasts, and whether you can manage your daily routine.Why Pain Occurs During LASEK RecoveryLASEK works by removing the corneal epithelium before reshaping vision with a laser. Following the procedure, the eye undergoes a process where the removed epithelium regenerates. During this regeneration phase, symptoms such as a foreign body sensation, stinging, increased tearing, and light sensitivity can occur. These symptoms are commonly referred to as "LASEK pain."Unlike LASEK, popular vision correction procedures such as LASIK or SMILE LASIK create a corneal flap or use a micro-incision technique, which leads to differences in initial discomfort. However, the ideal surgical method depends on individual corneal conditions and prescription requirements, with each approach offering distinct pros and cons.How Severe is LASEK Pain?LASEK pain varies from person to person. Most people experience the greatest level of discomfort between immediately after surgery and Days 2 to 3.Key Symptoms:Difficulty keeping eyes openGritty sensation, like sand in the eyeExcessive tearingIncreased light sensitivityGenerally, discomfort begins to ease starting around Days 3 to 4 as the corneal epithelium heals and recovers.Recovery Period and Returning to Daily LifeAfter LASEK surgery, protective contact lenses are placed on the eyes for a designated period, during which activities that strain the eyes should be limited. Tasks such as driving, prolonged screen time, and outdoor activities should be resumed gradually under medical guidance.Most patients can return to basic daily activities within about a week, though visual clarity stabilizes gradually over several weeks. Pain itself tends to concentrate within a short window, and long-term persistent pain is rare. However, the speed of recovery varies depending on individual eye conditions.What to Consider If You Are Worried About PainPain from LASEK is a normal part of the healing process inherent to the procedure. It is managed with prescribed medications and adequate rest. Rather than deciding on a surgical method based on pain alone, it is essential to consider the following factors together:Corneal thickness / Degree of myopia and astigmatismWork environment / Presence of dry eye syndromeNighttime vision requirementsAccurately evaluating your eye condition through a comprehensive examination is critical in determining the most suitable procedure for you.Key Takeaways from BGN Eye ClinicDiscomfort is concentrated primarily during the first 2 to 3 days after surgery.Symptoms tend to ease gradually after Days 3 to 4.Return to daily life is generally possible around 1 week post-op.Individual recovery speeds vary.To the question "Does LASEK hurt a lot?", we advise that while recovery pain is expected for a brief period, individual experiences vary. Receiving an accurate explanation and evaluation through a comprehensive eye examination is the best way to determine if LASEK is right for you.Overcome your fear of LASEK pain: find your answer through a comprehensive eye examination.

Is SMILE Pro Recovery Really Fast?Why Just One Day Makes a World of DifferenceHello, this is BGN Eye Clinic Jamsil Lotte Tower Branch.Before the day even started, I was already at maximum fatigue level because of a TV drama I watched last night that completely wrecked my peace of mind. As soon as I got home yesterday, I swore to myself, "Alright, I'm going to shower quickly and go straight to bed tonight." But right when I laid down, I realized a new episode of my favorite show was uploaded on OTT.So I told myself, "Just 10 minutes..." and hit play. But why did 10 minutes turn into 60? And why did 60 minutes turn into 180? What kind of physics law is this...?However, the "me" of tomorrow was... the "me" of this morning. As soon as I opened my eyes, I thought, "Ugh... if someone asks me about the SMILE Pro recovery period today, I feel like I'm going to cry first..." Carrying my swollen eyes, I barely made it to work.On my way in, I made another promise to myself: "Let's sleep early today. Today, for real." ...But I know myself best. This promise will likely crumble again around 10 PM tonight. (They said the preview for the next episode is out...)Here Comes the SMILE Pro Recovery Question Again TodayThe consultation room door opened ever so carefully, and a man in his early 30s poked his head in. Hesitating whether to close the door or not, he stepped in with a look that said, "If I turn back now, I don't think I'll ever build up the courage again..." He softly shut the door and sat down.Taking a deep breath out—phew—the very first words out of his mouth were:"Optometrist... is SMILE Pro recovery really that fast? My friend had SMILE LASIK and said they were completely fine after just one day."His tone was distinctly, "To be honest... I was so curious I couldn't even sleep well last night." I feel like I hear this exact question at least seven times a day. (Sometimes more than ten times...)Fiddling with his fingers, he added, "The thing is... if the recovery takes too long, my workload is going to be really tough..." His voice trembled slightly at the end. Trying to lighten the mood first, I made a small joke:"Sir, did you happen to stay up all night searching online? Things like 'SMILE LASIK recovery reviews,' 'LASEK recovery pain,' or 'SMILE Pro side effects'...?"He looked startled, instantly straightened up, and replied, "Oh... yes, that's right... YouTube's algorithm kept showing me scary videos..."In that moment, I felt so much empathy that I couldn't help but laugh. Most patients layer search upon search the night before, coming in worried as if they've been diagnosed with kidney failure... And I quietly muttered to myself, 'Right... someone said the exact same thing yesterday... Every video in the world is made to look scary...'Real Reasons Why SMILE Pro Recovery Feels So Fast1. The Recovery Speed Itself is DifferentThis is the first thing I explain during consultations. LASEK removes the corneal epithelium, making initial pain unavoidable and recovery naturally slower. Among those who get LASEK, quite a few call the clinic urgently on their way to work the next day because tears won't stop flowing. The recovery process can be that burdensome.On the other hand, because SMILE Pro uses a tiny incision, the initial recovery speed is noticeably fast. When patients visit the clinic the next day, they often open their eyes wide and say, "Huh? I had surgery yesterday... is it supposed to feel this fine?" Yes, that's completely normal. With SMILE Pro, returning to daily activities the next day is possible in most cases.2. Initial Pain is Significantly LowFor LASEK, the first 3–4 days are when your eyes throw a full tantrum. Tears flow heavily in bright places, and dryness and pain can be quite strong. During early LASEK recovery, people often realize, "Ah, so this is the pain everyone was talking about..." SMILE Pro is completely different.It is very rare for patients to contact the clinic due to pain. Even when they do, it's usually just "It feels a bit dry" or "My vision is slightly blurry." So during consultations, I often tell people, "Many SMILE Pro patients drink coffee and head straight to work the next day." And in reality, that's exactly what they do.3. Superior Corneal Stability for Long-Term ComfortIf your cornea is stable after testing, choosing SMILE Pro will likely feel much more comfortable. Because SMILE Pro utilizes a micro-incision technique, the structural stability of the cornea is well-preserved. This isn't just about "eyes feeling comfortable quickly after surgery", it long-term reduces redness, glare, and fatigue, making it a huge advantage for modern people who use their eyes for extended periods.An Optometrist's Honest ThoughtsDuring consultations in the clinic, there's a question patients ask almost like a requirement: "Optometrist, so which one is better? LASEK? Or SMILE Pro?"Whenever I hear this, my true inner thought is always:"Until I hear about your eye condition, profession, and lifestyle pattern, even I don't know which one is 'more right' for you...!"Honestly, it's true. Every procedure has its pros and cons, everyone's eyes are unique, and what you do for work and how you spend your day play a much bigger role in choosing the right surgical method.That's why I always start with these questions: "How many hours a day do you look at a monitor?", "What is your work intensity like?", "Can you take time off during the recovery period?", "Have you ever experienced dry eyes or light halos?"When going through these questions, 8 out of 10 people answer in a very similar pattern:Office workers, marketers, designers, developers, and corporate employees6 to 10 hours of monitor time per day (sometimes even more)"Recovery needs to be fast... I have to go to work...!"Pain or long-term discomfort is an absolute non-negotiableFor anyone matching these four traits, those with what we call the "typical modern eye lifestyle", SMILE Pro is actually a much better fit than LASEK. This isn't a marketing pitch; it's a realistic conclusion that optometrists like me deeply feel every day while conducting tests and consultations."Optometrist... Why Does SMILE Pro Change So Much in Just One Day?"The phrase I hear most from patients visiting the clinic the day after surgery is: "Huh? It's completely different from yesterday...! Why is recovery this fast?" So I explain to them: "SMILE Pro uses an extremely small incision. In fact, while you sleep, your eyes have a much greater capacity to heal."Then patients open their eyes wide and say, "Seriously, I woke up and my focus was suddenly crisp!"That's right. The key point of SMILE Pro recovery is that single day, more specifically, "one night's sleep." Because the incision in SMILE Pro is so microscopic, vision might be slightly hazy right after surgery, but after one deep sleep, vision clears up, dryness significantly decreases, and normal daily life becomes possible right away in many cases.Even After the Consultation EndsThe office worker who came in for a consultation today also took a breather after hearing all the explanations and cautiously asked: "Optometrist... I have to go back to work in two days. LASEK seems completely impossible for me... Will SMILE Pro really be okay?"I smiled and replied: "Yes! With a schedule like yours, SMILE Pro is far more realistic. So many people feel their vision become comfortable starting the very next day."Hearing that, his face brightened up with a smile as he said: "Ah... what a relief. I was honestly so worried, but it sounds like SMILE Pro fits me best. I suddenly feel way less scared."Watching his expression, I felt the tension drop from my shoulders as well. As soon as the door closed, I quietly murmured to myself: 'Yes. For working professionals, SMILE Pro really is a great choice.'If you are currently debating your options, don't worry too much and feel free to ask anytime. Through proper testing and consultation, we will help you find the most comfortable choice tailored to your recovery schedule, lifestyle pattern, and eye condition.

What is Apollo Eye Disease? Understanding Symptoms, Causes, and Treatment OptionsWhat is Apollo Eye Disease (Acute Hemorrhagic Conjunctivitis)? Causes, Symptoms, and Treatment Options[BGN Eye Clinic Jamsil Lotte Tower Branch]Hello, this is Dr. Park Se-kwang, Chief Physician at BGN Eye Clinic Jamsil.While many patients visit our clinic for vision correction, cataracts, and various ocular conditions, being an ophthalmology clinic means we also receive numerous inquiries regarding Apollo eye disease and various types of keratitis. Today, I would like to take the time to discuss in detail this eye condition that affects many people every year.What is Apollo Eye Disease?Apollo eye disease is a form of Acute Hemorrhagic Conjunctivitis in medical terms. It is a representative infectious eye disease primarily caused by Enterovirus 70, Coxsackievirus A24, or Adenovirus. Because it is highly contagious, understanding its transmission routes and thoroughly preventing infection is essential.Primary Causes and Transmission RoutesThis condition is a highly contagious viral infectious disease. After exposure to the virus, symptoms typically develop rapidly within 24 to 48 hours. Infection primarily occurs through the following routes:Physical Contact with an Infected Individual: Direct transmission of the virus via hands that have touched infected eyes.Sharing Contaminated Items: Indirect transmission through everyday items such as towels, handkerchiefs, doorknobs, computer keyboards, and smartphones.Visiting Crowded Public Places: Cross-infection in crowded environments including schools, workplaces, public transportation, and swimming pools.Potential Droplet Transmission: Possibility of airborne transmission via fine droplets from coughing or sneezing.Because Apollo eye disease is exceptionally contagious, the rate of transmission is extremely fast in group settings like schools, kindergartens, and offices. Therefore, early isolation and strict adherence to hygiene rules are essential.Frequently Asked Questions Before Treatment (Q&A)When diagnosed with Apollo eye disease or upon noticing early warning signs, many patients urgently ask practical questions right before visiting the clinic. Here are clear answers to the most common inquiries.Q1. Can I go to school or work as usual? What is the isolation period?Apollo eye disease is a highly contagious condition. The most contagious period is approximately one week after symptom onset. During this timeframe, it is a strict rule to avoid going to work or school and to remain isolated at home.Specifically for students, an official medical opinion note (or diagnostic certificate) can be issued after examination for attendance approval, so an early clinic visit is highly recommended.Q2. Can I just use existing eye drops or wear an eye patch from home?Using a family member's eye drops or old leftover medication on your own must be strictly avoided, as it can induce secondary bacterial infections or complications.Additionally, wearing an eye patch increases the temperature and humidity inside the eye area, creating the optimal environment for viral replication. Therefore, you should not wear an eye patch. It is best to leave the eye exposed to air circulation while administering prescribed eye drops.Stage-by-Stage SymptomsSymptoms begin with mild initial discomfort and show a clinical progression where conditions rapidly worsen.Initial Self-Examination SymptomsIt usually starts in one eye with a sensation of a foreign object or itching, quickly progressing to both eyes. The surrounding area becomes noticeably red, conjunctival hyperemia becomes severe, and the discharge of tears and sticky eye discharge increases.Advanced Stage SymptomsHemorrhaging appears as pinpoint or wide spots of blood on the sclera (white part of the eye), which is a classic characteristic of acute hemorrhagic conjunctivitis. Eyelid edema occurs where the eyelids swell uncomfortably, and photophobia (light sensitivity) accompanied by sharp pain upon light exposure, as well as temporary vision reduction, may occur.Essential Facts to Remember During TreatmentBecause Apollo eye disease is a viral infection, there is no single targeted cure that immediately eradicates the specific virus.In most cases, it naturally improves within 1 to 2 weeks as the body's immune system recovers.However, careful medical evaluation by an ophthalmologist is necessary during the course of the disease to prevent additional corneal damage, relieve pain, and avoid complications.Treatment and Prevention GuidelinesThe ultimate goal of treatment is to alleviate symptoms and prevent complications such as secondary bacterial infections and severe corneal opacity.Discomfort Relief TherapyCold Compress Application: Applying a cold compress using a clean pack over the eyelids effectively reduces swelling and stinging pain.Preservative-Free Artificial Tears: Frequently flushing the eyes with artificial tears physically washes away debris and viruses.Specialist Prescribed Eye Drops: Administering broad-spectrum antibiotic eye drops as directed by a doctor prevents secondary mixed bacterial infections.Prevention and Prognosis Guidelines Recommended by Dr. Park Se-KwangMany people tend to take the treatment process lightly due to memories of recovering easily from eye diseases during childhood. However, if the timing of proper care is missed and the virus deeply invades the cornea, it can induce corneal opacity, causing blurred vision and long-term vision impairment.If you detect any of the following warning signs, you must seek a detailed examination from a nearby ophthalmologist immediately:Heavy, severe eye pain accompanied by worsening blurred visionSwelling so severe that the eyelids can barely open, or deepening hemorrhagic spotsNo improvement after more than 7 days, or eye discharge turning yellow or pus-likeIf you suspect symptoms of Apollo eye disease, please visit BGN Eye Clinic for prompt diagnosis and professional care to safeguard your vision.

“Are There Any LASIK Side Effects?” Top 5 Parents' Q&As Answered by an OptometristHello, this is BGN Eye Clinic at Jamsil Lotte Tower.Today, we would like to address the questions that parents, rather than patients themselves, frequently ask us. A significant portion of our patients considering vision correction procedures such as LASIK, LASEK, and SMILE LASIK are in their 20s. Especially during school vacation periods, we receive a high volume of inquiries, visits, and surgery bookings from university students. Naturally, this leads to many inquiries from the parents who accompany them.“My child wants to get eye surgery. Is it really safe?”“What if something goes wrong…?”“Will their eyesight deteriorate again after surgery?”It is completely understandable for parents to feel anxious when their children decide to undergo eye surgery. Whenever parents mention reading negative online reviews telling people not to get LASIK, we deeply empathize with their concern. Because it involves their child, parents naturally want complete reassurance that this is truly a safe and right choice.Therefore, today we have compiled and detailed the most common questions from parents from an optometrist's perspective, just as we would during an actual consultation. If you are currently concerned about your child's upcoming vision correction surgery, we hope this guide provides clarity and peace of mind.Vision Correction Surgery for Your Child: Top Parents' Q&AQ1. Is LASIK surgery genuinely safe?This is one of the most frequently asked questions. Parents want to confirm beyond doubt that the procedure is medically safe.At BGN Eye Clinic, we utilize state-of-the-art diagnostic equipment and comprehensive pre-operative examinations to thoroughly assess the patient's eye condition. We only proceed with surgery when strict medical eligibility criteria are fully met. We evaluate more than 10 critical parameters, including corneal thickness, astigmatism axis, and refractive error. Based on these precise results, we determine surgical candidacy and guide you through accurate, personalized medical consultations.Q2. I heard that vision can change again even after surgery. Is that true?The human eye does not stop aging or changing simply because it has undergone surgery. Just like other organs such as the hands or brain, the eyes can undergo subtle, natural changes over time due to aging, fatigue, and environmental factors.Occasionally, parents worry that post-operative changes in vision represent a complication or side effect, but in most cases, these are simply natural physiological changes over time.Q3. Does having to wear glasses again after LASIK mean the surgery failed?For patients with high myopia or thin corneas, we may intentionally leave a minimal degree of refractive error during surgery to prioritize long-term ocular safety. Additionally, as patients age and experience presbyopia, many choose supplementary reading glasses to optimize distant or near focus.In the vast majority of cases, patients enjoy their daily lives completely free of glasses after surgery. The core objective is ensuring that vision correction is tailored to each patient's specific ocular profile, providing maximum daily comfort and clarity.Q4. Isn't my child too young to undergo LASIK?This is another top concern brought up by parents! There is often a clear difference in perspective between university-aged patients and their guardians. Students are eager to undergo surgery promptly now that they are adults, while parents worry whether it might be premature. We frequently observe this debate during actual consultations.Generally, physical growth stops once an individual reaches adulthood. If the patient meets all necessary medical criteria, they can decide on surgery following a thorough evaluation with our surgeons. The reason many people consider surgery in their 20s or 30s relates to optimal recovery speed and eye health. Since presbyopia typically begins after age 40, many choose to consult with us prior to that stage.Most importantly, our clinic prioritizes listening to, empathizing with, and making decisions together with parents. In fact, we frequently advise: “It is perfectly fine to complete only the examination today, discuss it thoroughly with your parents at home, and return together later.”Q5. My child is a college student. Can they decide on their own without parental consent?Legally, adults have the full autonomy to decide on surgical procedures independently. However, we strongly encourage open discussion and mutual agreement with parents before proceeding.In practice, our optometrists frequently speak directly with parents over the phone or provide additional detailed explanations before the surgery date. We firmly believe that creating an environment where the family feels entirely reassured and aligned yields the highest overall satisfaction after surgery.Q6. How experienced are the operating surgeons?Parents often ask about our surgeons' qualifications during phone inquiries or consultations. This serves as their final reassurance that they have chosen the right clinic.The chief surgeons at BGN Eye Clinic are board-certified ophthalmologists with extensive clinical and surgical experience. Details regarding surgeon schedules and specialties are fully provided during consultations, and direct physician discussions are always arranged when needed.It is entirely natural for parents to worry about whether the surgery is safe and whether their child might regret it later. We believe parental concern is simply another expression of love.That is why our consultations aim not only to explain surgical technicalities, but also to build genuine trust with parents. As optometrists, we strive in every session to explain every step of the procedure clearly while easing any underlying anxiety.Our most rewarding moments come when parents tell us that their minds are completely at ease after our discussion.
