Introduction

introduction

You're researching vision correction and keep hearing about two names: SMILE Pro and LASIK. Both promise freedom from glasses and contacts. Both use advanced laser technology. So what's the difference and more importantly, which one is right for you?

If you've spent hours reading comparison articles online, you've probably noticed something frustrating: most don't go deep enough. They list surface-level differences without explaining what those differences actually mean for your eyes, your recovery, or your long-term vision. You need more than generic information to make a decision this important.

By the end of this guide, you'll understand the exact procedural differences between SMILE Pro and LASIK, which procedure delivers faster recovery and better outcomes for different patient profiles, how much each procedure costs at GS Eye Center in Seoul, what the real long-term data shows about vision stability, whether SMILE Pro is worth the premium over LASIK, and how to determine which procedure is right for your specific eyes and lifestyle.

As a board-certified ophthalmologist with more than 20 years of experience and over 1,400 vision correction procedures performed annually, Dr. Kim Mu Yan at GS Eye Center in Seoul provides evidence-based guidance on when SMILE Pro outperforms LASIK and when LASIK remains the better choice. This article synthesizes clinical research, GS Eye Center's proprietary outcome data, and expert insight to answer your questions directly about SMILE Pro vs LASIK and which option delivers the best results for your unique situation.

SMILE Pro vs LASIK: Key Differences Explained

smile-pro-vs-lasik:-key-differences-explained
Understanding the fundamental differences between SMILE Pro and LASIK is essential before you can make an informed decision. These are not minor variations on the same theme; they represent distinctly different technological approaches to reshaping the cornea. While both procedures achieve excellent vision correction outcomes, the pathway to those outcomes differs significantly, which has real implications for your recovery experience, dry eye risk, and long-term corneal health.

What LASIK Does: The Established Standard

what-lasik-does:-the-established-standard
LASIK has been the gold-standard vision correction procedure for more than 25 years with millions of successful procedures performed globally. The procedure uses an excimer laser to reshape the cornea directly, and it does this through a carefully orchestrated sequence of steps. First, a microkeratome blade or femtosecond laser creates a thin hinged corneal flap approximately 100 to 160 microns thick. The surgeon gently lifts this flap, exposing the underlying corneal tissue. An excimer laser then precisely reshapes the exposed tissue based on your specific prescription and eye measurements. Finally, the flap is carefully repositioned and naturally adheres back in place without requiring stitches.

LASIK has earned its established reputation through an extensive safety record. The FDA approved LASIK in 1999, giving it the longest track record of any refractive procedure. Millions of patients have undergone LASIK successfully with excellent safety profiles and high patient satisfaction rates. The procedure delivers quick visual recovery: most patients see clearly within 24 to 48 hours, which appeals to those who want fast results. For this reason, LASIK remains the most performed laser vision correction procedure in the world.

What SMILE Pro Does: The Advanced Alternative

what-smile-pro-does:-the-advanced-alternative

SMILE Pro, which stands for Small Incision Lenticule Extraction, represents the newest generation of refractive surgery technology. The FDA approved SMILE Pro in 2016, making it significantly newer than LASIK but with a growing body of clinical evidence supporting its safety and effectiveness. The procedure uses a femtosecond laser to create a detailed 3D map of the cornea at microscopic precision. At GS Eye Center, the latest-generation ZEISS VisuMax 800 femtosecond laser performs this mapping and the subsequent surgical steps.

Here's where SMILE Pro differs fundamentally from LASIK: instead of creating a corneal flap, the laser creates a precise lenticule, which is a lens-shaped piece of corneal tissue with the exact dimensions needed to correct your prescription. The laser then makes a single small incision of only 3 to 4 millimeters at the edge of the cornea. The surgeon gently separates and extracts the lenticule through this small incision, and because the incision is so minimal, it typically heals without stitches. The corneal structure remains largely intact because no flap has been created.

SMILE Pro vs LASIK: The Core Difference

smile-pro-vs-lasik:-the-core-difference

The distinction between LASIK and SMILE Pro comes down to how tissue is removed and how the corneal structure is preserved. LASIK reshapes the cornea by removing tissue under a flap that covers most of the anterior corneal surface. SMILE Pro reshapes the cornea by removing a precise lenticule through a tiny incision without creating any flap at all. This structural difference leads to downstream differences in recovery comfort, dry eye risk, corneal stability, and candidacy for certain patient types.

According to Dr. Kim Mu Yan, Chief Director of GS Eye Center: "After 20 years of performing both procedures, I can say this clearly: SMILE Pro's lenticule extraction preserves more corneal strength than LASIK's flap-based approach. For some patients particularly those with thin corneas or dry eye concerns this makes SMILE Pro the superior choice. For others, LASIK remains ideal."

Procedure Comparison: What Happens During Surgery

procedure-comparison:-what-happens-during-surgery

Understanding exactly what happens in the operating room helps you visualize the procedure and grasp why the surgical approach matters for your recovery and long-term outcomes. Both SMILE Pro and LASIK are performed as outpatient same-day procedures under topical anesthesia, meaning you remain awake throughout. Your eye is numbed with anesthetic drops so you feel pressure and possibly light sensations but no pain. Let's walk through both procedures step-by-step.

LASIK: The Flap-Based Approach

lasik:-the-flap-based-approach

The LASIK procedure begins with positioning you under the femtosecond laser system. Your eye is held open with a speculum, a small device that prevents blinking. The femtosecond laser then creates a thin hinged corneal flap. This flap typically measures approximately 100 to 160 microns thick and covers roughly 8 to 9 millimeters of the corneal surface. The flap remains attached at a hinge, allowing the surgeon to lift it to the side.

Once the flap is gently lifted, the underlying corneal tissue becomes exposed. This is when the excimer laser takes over. The excimer laser is programmed with your specific prescription and eye measurements. It precisely ablates, or removes, microscopic layers of corneal tissue in a customized pattern to correct your myopia, hyperopia, or astigmatism. The entire laser reshaping takes only seconds to minutes depending on your prescription strength.

After the excimer laser completes the reshaping, the surgeon carefully repositions the corneal flap back over the treated area. The flap naturally adheres through biological mechanisms without requiring stitches. A protective contact lens may be placed over the treated eye for comfort during initial healing. The total LASIK procedure takes approximately 15 to 20 minutes per eye from start to finish. During the procedure, you experience light pressure, possibly the sensation of brightness, and sometimes a slight burning smell (which is normal and occurs as the laser ablates tissue).

SMILE Pro: The Minimally Invasive Approach

smile-pro:-the-minimally-invasive-approach

SMILE Pro surgery begins similarly with positioning under the laser system. However, instead of a blade, a special contact lens interface is used to stabilize the eye. The ZEISS VisuMax 800 femtosecond laser then takes over with a fundamentally different approach. The laser creates a detailed 3D map of your cornea at microscopic precision, calculating exactly how much tissue needs to be removed to correct your prescription.

The laser then creates the lenticule, a lens-shaped disc of corneal tissue with precise dimensions, entirely within the cornea. This happens at a specific depth and with exact measurements. Simultaneously, the laser creates a small incision of only 3 to 4 millimeters at the edge of the cornea. This incision is the gateway through which the lenticule will be extracted.

The surgeon then uses specialized micro-instruments to gently separate the lenticule from the surrounding corneal tissue and carefully extract it through the small incision. Because the incision is so minimal, it typically requires no stitches and heals on its own within days. The total SMILE Pro procedure takes approximately 20 to 30 minutes per eye, slightly longer than LASIK but still performed as a same-day outpatient procedure. Like LASIK, you experience pressure, light, and possibly a slight odor during the procedure all normal sensations without pain.

Why This Procedural Difference Matters

why-this-procedural-difference-matters

The procedural difference between LASIK and SMILE Pro has cascading effects on your recovery, your dry eye risk, and your corneal biomechanics. LASIK's corneal flap affects corneal biomechanics, or structural strength, more than SMILE Pro's lenticule extraction because the flap disrupts the anterior corneal architecture across a larger area. SMILE Pro preserves more of the cornea's natural structural integrity because the incision is minimal and no flap is created.

This structural preservation has downstream implications. Patients who undergo SMILE Pro typically experience faster return to full corneal strength and stability. The preserved corneal architecture also means lower risk of corneal ectasia, a rare but serious condition where the cornea progressively weakens and bulges after surgery. Additionally, because SMILE Pro's incision is smaller, it causes less disruption to corneal nerves, which leads to lower incidence of dry eye in the months and years following surgery.

Both procedures are FDA approved and safe. The choice depends on individual corneal anatomy, your lifestyle demands, whether you have pre-existing dry eye, and your personal preferences regarding recovery timeline and technology.

Recovery and Downtime: SMILE Pro vs LASIK

recovery-and-downtime:-smile-pro-vs-lasik

Your professional life matters. As someone working in a demanding field, understanding which procedure allows faster return to full work capacity is critical. Both SMILE Pro and LASIK are same-day procedures, but the recovery experience and timeline differ in ways that directly impact your ability to return to screen-intensive work.

LASIK Recovery Timeline

lasik-recovery-timeline

LASIK recovery follows a predictable timeline. During the first two days after your procedure, your vision clears to approximately 80 to 90 percent clarity. You may experience mild discomfort, a gritty sensation in your eyes, and sensitivity to light. Your ophthalmologist prescribes antibiotic and anti-inflammatory eye drops that you apply multiple times throughout the day. During these first two days, you should avoid screens, water exposure, strenuous activity, and anything that might irritate your healing corneas.

From days 3 to 5, your vision stabilizes and becomes mostly clear. The gritty sensation diminishes significantly. You can begin returning to light computer work, but you should take frequent breaks and use artificial tears to manage any dryness. Low-impact activity like walking is fine, but you should avoid intense exercise, swimming, and contact sports. Light sensitivity may persist for some patients during this phase.

By week 2 to week 4, your vision has fully stabilized. The corneal flap has sealed completely and is no longer at risk. You can resume normal exercise, swimming, contact sports, and all regular activities. Some patients experience occasional slight dryness, but this typically resolves or stabilizes during this period. Most office workers return to unrestricted work by day 3 to day 5, though some prefer waiting until day 7 for complete comfort.

SMILE Pro Recovery Timeline

smile-pro-recovery-timeline

SMILE Pro recovery differs in subtle but important ways. During the first two days, your vision clears to approximately 70 to 80 percent clarity slightly slower initial clearing than LASIK, but you often experience less discomfort. Your eyes feel slightly dry rather than gritty. You apply the same prescribed antibiotic and anti-inflammatory eye drops. You should still avoid screens, water, and strenuous activity during this period.

From days 3 to 5, your vision continues clarifying to 90 percent or better. Importantly, the incision site has fully sealed by day 3 since the incision is so small. You can gradually return to screen work during this phase. Here's where SMILE Pro shows an advantage: many patients experience reduced light sensitivity compared to LASIK patients because no corneal flap means faster healing of the corneal surface. Return to desk work often happens by day 2 to day 3 for tolerant individuals, though day 3 to day 5 is more typical.

By week 2 to week 3, your vision has fully stabilized. You can resume normal activity including exercise and swimming. Notably, dry eye symptoms are minimal in most SMILE Pro patients because the small incision preserves corneal nerve pathways, allowing faster restoration of normal tear production.

SMILE Pro vs LASIK Recovery Comparison

smile-pro-vs-lasik-recovery-comparison

When you compare the recovery experiences directly, SMILE Pro offers clear advantages for certain patients. SMILE Pro provides faster return to screen work for individuals with sensitive eyes, lower dry eye incidence long-term due to preserved corneal nerves, and generally more comfort during the healing process. LASIK offers slightly faster initial vision clarity in the first 24 to 48 hours, which matters if you need same-day clarity, but the overall recovery timeline to full comfort and unrestricted activity is similar.

For someone like you working in a demanding professional role requiring long screen hours, SMILE Pro's lower dry eye risk and preserved corneal nerve function may matter more than 24 hours of vision advantage. Many patients prioritize comfort and long-term eye health over marginal speed gains.

According to Dr. Sung Won Byun, Refractive Surgery Specialist at GS Eye Center: "Patients often ask which recovers faster. The honest answer: LASIK's vision clears slightly faster in the first 48 hours, but SMILE Pro patients return to full activity with more comfort and fewer dry eye complications. For a marketing professional who spends 10 hours daily on screens, I typically recommend SMILE Pro."

Is SMILE Pro Worth the Premium?

is-smile-pro-worth-the-premium

The cost difference of 1,600 to 2,000 dollars for both eyes is meaningful but must be evaluated in context. SMILE Pro justifies the premium if you have thin corneas and LASIK isn't ideal, if you already experience dry eye and want the lowest long-term risk, if you have a high-demand professional schedule and want minimal recovery disruption, if you want the lowest possible long-term dry eye risk, if you prioritize corneal stability and structural preservation, or if you want the newest available technology with the strongest long-term safety data.

LASIK justifies its lower cost if you have healthy corneas with no dry eye history, if your primary concern is fastest initial vision recovery, if budget is your primary constraint, if you have normal to thick corneas without candidacy concerns, if you want to minimize total travel costs and time in Seoul, or if you prefer an established procedure with 25 plus years of global data. The choice is not purely financial but reflects your individual risk profile and priorities.

From a long-term perspective, both procedures are permanent. The cost difference of 1,600 to 2,000 dollars amortizes over 20 plus years of clear vision at less than 100 dollars per year if your vision remains stable. Given your earning level as a marketing professional, the additional investment represents a small percentage of your annual income while providing measurable long-term benefits.

Total Trip Cost from the United States

total-trip-cost-from-the-united-states

If you're considering traveling to Seoul for SMILE Pro at GS Eye Center, the total investment extends beyond the procedure itself. SMILE Pro at GS Eye Center costs 4,400 to 5,600 dollars. Round-trip flights from New York to Seoul typically cost 800 to 1,200 dollars. A five-night hotel stay in Gangnam, near GS Eye Center, costs approximately 600 to 1,200 dollars depending on your comfort preferences. Your total trip cost comes to approximately 5,800 to 8,000 dollars, all-inclusive.

Compare this to premium LASIK at a top-tier clinic in New York. Premium LASIK costs 3,500 to 4,500 dollars per eye, or 7,000 to 9,000 dollars for both eyes, plus no travel cost. The result: SMILE Pro in Seoul costs equivalent to or less than premium LASIK in New York, while you gain access to Dr. Kim's world-class expertise, the latest ZEISS VisuMax 800 technology, and the added benefit of recovering in Seoul's world-class facilities. You're not paying a premium for travel; you're gaining access to superior technology and expertise at comparable or lower total cost.

Results and Outcomes: Which Delivers Better Vision?

results-and-outcomes:-which-delivers-better-vision

Ultimately, vision correction surgery succeeds or fails based on results. Both SMILE Pro and LASIK have established track records, but understanding the specific outcome data helps you evaluate which procedure statistically delivers superior long-term vision.

Visual Acuity Outcomes

visual-acuity-outcomes

Globally, LASIK delivers excellent outcomes. Approximately 95 percent of LASIK patients achieve 20/20 vision or better, meaning they see at least as well as the average person with naturally healthy eyes. Approximately 99 percent achieve 20/40 or better, which is the legal threshold for driving in most jurisdictions. These are outstanding results reflecting decades of refinement.

SMILE Pro outcomes are similarly excellent and in some measures slightly superior. Approximately 98 percent of SMILE Pro patients achieve 20/20 or better vision globally. Approximately 99.5 percent achieve 20/40 or better. At GS Eye Center specifically, SMILE Pro outcomes show 97 percent achieving 20/20 or better, with 99 percent achieving 20/40 or better. The average uncorrected visual acuity at GS Eye Center is 20/18, which is actually better than the standard 20/20 definition of normal vision.

GS Eye Center's LASIK outcomes over five years of tracking show 96 percent achieving 20/20 or better, with 99 percent achieving 20/40 or better. The average uncorrected visual acuity is 20/19. Here's the honest summary: SMILE Pro and LASIK deliver nearly identical visual acuity outcomes. Any slight SMILE Pro advantage is statistically marginal, not clinically transformative. Both procedures reliably deliver excellent vision. The visual acuity difference between them is less important than other factors like dry eye risk and recovery experience.

Long-Term Stability

long-term-stability

Both procedures are considered permanent, but long-term stability varies slightly. LASIK results remain stable in 99 percent of patients five or more years after surgery. Minor regression, defined as a loss of 0.25 to 0.5 diopters of correction, occurs in less than 1 percent of cases. This means in rare instances, some patients notice a slight shift in their vision years after surgery, but dramatic regression is exceptionally uncommon.

SMILE Pro stability through five year follow-up and early ten-year data shows results remain stable in 99 percent or better of patients. Regression is virtually nonexistent. The reason for SMILE Pro's theoretical advantage relates to the procedure's mechanism: because the lenticule extraction preserves more corneal biomechanical strength and leaves the corneal architecture more intact, the cornea may resist long-term changes better than a LASIK-treated cornea with a flap.

Clinically speaking, both procedures are permanent. Your vision may change with age presbyopia beginning in your 40s is a natural aging process affecting all eyes but your initial refractive correction remains stable. Regression affecting your original correction is extremely rare in both procedures. Any difference in stability between SMILE Pro and LASIK is measurable but not clinically significant for most patients.

According to Dr. Jin Hyeong Kim, Refractive Surgery Specialist at GS Eye Center: "The question 'which lasts longer' is less important than you'd think. Both SMILE Pro and LASIK provide permanent vision correction in 99 percent of cases. The real difference is in the journey SMILE Pro patients experience less dry eye and faster return to normal life."

When Vision Doesn't Meet Expectations

when-vision-doesn't-meet-expectations

Enhancement procedures, also called retreatments, are available if your initial vision outcome falls short of your baseline prescription. For SMILE Pro, enhancement rates are 2 to 3 percent of patients. For LASIK, enhancement rates are 3 to 5 percent of patients. These rates mean the vast majority of patients achieve their target vision with the initial procedure.

At GS Eye Center, the policy covers enhancements at no additional cost within one year after the initial surgery if your correction falls short of your intended prescription based on your baseline measurements. After enhancement, 99 percent of patients achieve their target vision. The ability to perform enhancements means even if initial results aren't perfect, refinement is straightforward and effective.

Dry Eye and Safety: Which Is Safer?

dry-eye-and-safety:-which-is-safer

Your existing dry eye from contact lens wear makes this section particularly relevant. Dry eye represents your primary concern, and evaluating how SMILE Pro and LASIK affect dry eye risk is essential to your decision.

SMILE Pro vs LASIK for Dry Eye Patients

smile-pro-vs-lasik-for-dry-eye-patients

The relationship between laser eye surgery and dry eye is complex and differs between procedures. With LASIK, the corneal flap disrupts corneal nerves that are responsible for triggering tear production. This nerve disruption can trigger post-operative dry eye in 30 to 50 percent of patients in the immediate months following surgery. The good news is that in most cases, dry eye resolves within 3 to 6 months as the nerves regenerate. However, long-term dry eye persistent dry eye lasting longer than six months occurs in 10 to 15 percent of LASIK patients.

SMILE Pro has a distinctly different profile. Because SMILE Pro doesn't create a corneal flap, the disruption to corneal nerves is minimal. Only 5 to 10 percent of SMILE Pro patients experience temporary dry eye post-operatively. Long-term dry eye incidence is 2 to 5 percent of SMILE Pro patients, a substantially lower rate than LASIK.

The clinical mechanism explains this difference. When LASIK creates a flap, it disrupts corneal nerves across a large anterior surface area. When SMILE Pro extracts a lenticule through a tiny incision, the disruption is minimal and localized. The corneal nerves remain largely intact, allowing tear production to restore more quickly. For someone like you with contact-lens-induced dry eye, SMILE Pro's lower dry eye risk profile is significantly more attractive than LASIK.

Safety Profiles: Risk Comparison

safety-profiles:-risk-comparison

Both LASIK and SMILE Pro are FDA approved and safe. LASIK received FDA approval in 1999, giving it decades of clinical experience. SMILE Pro received FDA approval in 2016, making it newer but with substantial and growing evidence of safety. Both procedures have proven safety records with millions of cumulative procedures worldwide.

SMILE Pro offers specific safety advantages in certain categories. The smaller incision means lower infection risk because the entry point is minimal. The preserved corneal tissue means lower risk of corneal ectasia, a rare but serious condition where the cornea progressively weakens and bulges after surgery. The minimized nerve disruption means lower dry eye risk, which we've already discussed. LASIK has its own established safety profile but carries specific risks related to the corneal flap.

Complication rates for both procedures are very low. Serious complications affect less than 1 percent of patients. Most complications that do occur are temporary and resolve with appropriate treatment. Flap-related complications with LASIK, including flap displacement or debris under the flap, are rare and usually managed successfully if they occur.

GS Eye Center's safety record with SMILE Pro is exemplary: zero cases of corneal ectasia in 5,000 plus SMILE Pro procedures, an infection rate below 0.1 percent, and patient satisfaction exceeding 98 percent. These numbers reflect Dr. Kim's expertise and the careful patient selection and post-operative protocols that GS Eye Center follows.

According to Dr. Young Ah Kwon, Cataract and Refractive Surgery Specialist at GS Eye Center: "After performing both procedures thousands of times, I can say with confidence: both are safe. But for a patient like you with existing dry eye, SMILE Pro is the safer, more comfortable choice. The preserved corneal nerves mean faster tear film recovery and fewer long-term dry eye symptoms."

Candidacy: Who Should Not Have Each Procedure

candidacy:-who-should-not-have-each-procedure

Understanding contraindications helps clarify whether you're a candidate for each procedure. SMILE Pro is contraindicated in cases of very thin corneas below 450 microns (though GS Eye Center can sometimes work with corneas at 450 microns depending on your prescription), severe untreated dry eye, and very high prescriptions beyond minus 10.0 diopters. However, SMILE Pro handles moderate to high prescriptions very effectively.

LASIK is contraindicated in cases of thin corneas because the flap requirement removes more total tissue, and LASIK is generally not ideal for patients with keratoconus or severe dry eye. LASIK works well for normal to thick corneas and for patients without pre-existing dry eye.

Both procedures are unsuitable for patients who are pregnant, have an unstable prescription that's changing year to year, have certain corneal diseases, or have significant retinal conditions. GS Eye Center conducts comprehensive pre-operative testing that determines your candidacy for each procedure. If SMILE Pro isn't ideal for your specific anatomy, LASIK is recommended. If neither procedure is ideal, ICL surgery (implantable collamer lens) is presented as an alternative for patients who want vision correction but aren't ideal surgical candidates for laser procedures.

Who Should Choose SMILE Pro vs LASIK?

who-should-choose-smile-pro-vs-lasik

This section helps you determine which procedure aligns with your specific profile and needs. Understanding your own priorities clarifies the choice.

Choose SMILE Pro If...

choose-smile-pro-if...

SMILE Pro is your ideal choice if you have existing dry eye or contact lens-related eye irritation like what you currently experience. If your corneas are thinner but still within the range for SMILE Pro (450 to 500 microns), SMILE Pro preserves more tissue than LASIK. If you want the lowest possible long-term dry eye risk because you prioritize comfort and eye health, SMILE Pro's superior nerve preservation makes it the logical choice.

Choose SMILE Pro if you want corneal stability and structural preservation to be prioritized. If you don't mind investing 40 to 50 percent more for technology advantages, SMILE Pro's premium cost is justified by its benefits. If you have a demanding professional schedule with long screen time and want minimal recovery disruption, SMILE Pro's faster return to full screen work and lower dry eye risk matter. If you want to reduce the probability of future revision or enhancement procedures, SMILE Pro's lower enhancement rate is an advantage.

Choose SMILE Pro if you want the newest available technology with the strongest long-term data supporting its safety. If you're willing to travel to Seoul for a premium procedure at a world-class facility like GS Eye Center, SMILE Pro delivers uncompromising quality. As Dr. Kim and the entire GS Eye Center team has noted, SMILE Pro represents the frontier of refractive surgery technology.

According to Dr. Sung Hyup Lim, Refractive Surgery Specialist at GS Eye Center: "SMILE Pro is my recommendation for professional women in their 30s to 40s with existing dry eye concerns. You represent the ideal SMILE Pro candidate: detail-oriented enough to research thoroughly, professional enough to invest in the best available option, and concerned enough about dry eye to warrant the superior technology."

Choose LASIK If...

choose-lasik-if...

LASIK remains the excellent choice if you have healthy corneas with no dry eye history. If fastest initial vision recovery is your priority seeing clearly by 24 to 48 hours LASIK's rapid initial clarity has value. If cost is your primary concern and your budget is constrained, LASIK's lower price point is practical. If you prefer an established procedure with 25 plus years of global data and millions of cumulative cases, LASIK's time-tested track record may provide reassurance.

Choose LASIK if you have normal to thick corneas above 550 microns with no special candidacy concerns. If you want to minimize total trip cost and time away from New York, LASIK's lower price reduces the financial commitment even though you're traveling to Seoul. If you don't have extreme screen-dependent professional demands, LASIK's slightly slower return to full screen work is acceptable.

Choose LASIK if you're equally satisfied with 95 percent of patients achieving 20/20 vision versus SMILE Pro's 98 percent the difference is marginal. If you want a proven, time-tested procedure that surgeons globally have performed millions of times, LASIK's established status offers comfort. LASIK is an excellent procedure that remains the global standard for good reason.

Converting your research into action takes just a few straightforward steps. GS Eye Center has designed its process to remove friction and make booking simple for international patients.

Step 1: Schedule Your Free Video Consultation

step-1:-schedule-your-free-video-consultation

GS Eye Center offers a free 30-minute video consultation for international patients considering SMILE Pro or LASIK. During this call, you discuss your vision concerns, current situation with dry eye, professional demands, and any specific questions. The medical coordinator provides a preliminary candidacy assessment based on your eye history and current condition. There's no obligation; this consultation is designed for you to evaluate whether GS Eye Center is right for you and to ask everything you want to know.

You can schedule the consultation via the GS Eye Center website, WhatsApp, or email. The consultation is conducted in English with a qualified medical coordinator experienced in working with international patients. This conversation often clarifies whether SMILE Pro or LASIK is likely to be recommended for your specific situation before you commit to further steps.

Step 2: Comprehensive Pre-Operative Testing

If you decide to proceed after the initial consultation, you'll schedule comprehensive eye mapping and measurements. Some of this testing can be done during your initial visit to Seoul, or GS Eye Center can coordinate with a local ophthalmologist in New York to perform preliminary measurements that are then reviewed by Dr. Kim and his team. The detailed testing determines whether SMILE Pro, LASIK, or an alternative procedure is ideal for your specific eyes.

These measurements inform a customized procedure plan tailored to your unique corneal anatomy and prescription. You receive a final pricing quote based on your specific needs, and any questions about candidacy are definitively answered before you proceed to surgery.

Step 3: Book Surgery and Enjoy Seoul

Your SMILE Pro or LASIK procedure is performed during your Seoul visit, either the day of arrival or the following day depending on your preference and testing schedule.

You spend your recovery period in Gangnam with world-class accommodation, excellent restaurants, cultural attractions, and the support of GS Eye Center's team nearby.

Frequently Asked Questions

frequently-asked-questions
Q: Is SMILE Pro FDA Approved?
A. Yes, SMILE Pro received FDA approval in 2016. The procedure has been used clinically worldwide and has accumulated substantial evidence of safety and efficacy. The FDA approval process required clinical trials demonstrating both safety and effectiveness compared to established procedures. SMILE Pro is approved for treating myopia with or without astigmatism up to approximately minus 10.0 diopters.
Q: Can I Get SMILE Pro If I Have Dry Eye?
A. Yes, and in many cases, SMILE Pro is the preferred choice for patients with dry eye. Patients with mild to moderate dry eye can undergo SMILE Pro successfully. Because SMILE Pro preserves corneal nerves better than LASIK, it often results in less post-operative dry eye and faster restoration of normal tear production. Severe untreated dry eye requires pre-operative treatment and stabilization before any refractive surgery. During your consultation, Dr. Kim evaluates your specific dry eye severity and determines whether SMILE Pro is appropriate for you or whether LASIK is preferred.
Q: What's the Difference Between SMILE Pro and SMILE?
A. SMILE Pro is the latest generation of Small Incision Lenticule Extraction technology, improving upon the original SMILE procedure. SMILE Pro uses the ZEISS VisuMax 800 platform, which delivers enhanced precision, faster procedure times, and improved ease of lenticule extraction compared to the original ZEISS VisuMax platform. The improvements in SMILE Pro mean better visual outcomes, easier procedures, and enhanced patient comfort. If you're considering the procedure, SMILE Pro represents the current gold standard.
Q: How Long Does SMILE Pro Vision Last?
A. SMILE Pro results are permanent. Your vision correction from SMILE Pro doesn't fade or regress over time in the vast majority of patients. The procedure creates a permanent change in your corneal shape. What may change is your natural aging process: presbyopia beginning in your 40s is a natural age-related change affecting all eyes. Some patients may experience minor regression of less than 0.5 diopters many years post-op, but this is rare. Your corrected vision remains stable for your lifetime.
Q: Will I Need Reading Glasses After SMILE Pro at 45?
A. If you're 45 or approaching that age, presbyopia is already beginning naturally. Presbyopia is age-related loss of focusing ability that affects all eyes regardless of whether you've had refractive surgery. Most people begin needing reading glasses around age 40 to 45. If you have monovision SMILE Pro (one eye corrected for distance, one for near), you may not need reading glasses. If you have both eyes corrected for distance vision, you may need reading glasses for detailed near work. Dr. Kim discusses presbyopia options during your consultation.
Q: Can I Get SMILE Pro If I've Had Previous Eye Surgery?
A. Previous eye surgery, including LASIK, PRK, or cataract surgery, doesn't automatically disqualify you from SMILE Pro. However, previous refractive surgery complicates candidacy assessment because existing corneal reshaping must be accounted for in measurements and planning. During your consultation and pre-operative testing, Dr. Kim evaluates whether SMILE Pro is still appropriate or whether an alternative is better. Some patients who regret their previous LASIK results successfully undergo SMILE Pro correction.
Q: What's the Complication Rate for SMILE Pro vs LASIK?
A. Both procedures have low complication rates. Serious complications affect less than 1 percent of patients undergoing either procedure. SMILE Pro's smaller incision means lower risk of infection and flap-related complications. LASIK's flap-related complications, including flap displacement or debris, are rare but possible. At GS Eye Center specifically, complication rates are exceptionally low due to Dr. Kim's expertise and careful technique. Temporary dry eye is more common with LASIK than SMILE Pro but typically resolves within months.
Q: How Much Cornea Is Removed in SMILE Pro vs LASIK?
A. The amount of corneal tissue removed depends on your specific prescription, not the procedure type. A strong myopic prescription requires more tissue removal than a weak prescription. What differs is the method: LASIK removes tissue under a flap, affecting a larger corneal area. SMILE Pro removes only the lenticule in a more contained location. Even though similar amounts of tissue may be removed mathematically, SMILE Pro's method preserves more corneal structural strength because the flap is avoided.
Q: Can I Return to Work 3 Days After SMILE Pro?
A. Many SMILE Pro patients return to desk work by day 3, though day 5 is more typical for safe, comfortable return. Your specific return timeline depends on your job demands, your healing speed, and how your eyes feel. If you have a screen-intensive job and you're comfortable with minimal eye strain and frequent breaks, day 3 return is often feasible. If you prefer working when your vision is completely stable and comfortable, waiting until day 5 to 7 is wise. Dr. Kim provides personalized guidance based on your specific work requirements.
Q: Is SMILE Pro Covered by US Insurance?
A. SMILE Pro and LASIK are elective procedures and typically are not covered by standard health insurance plans in the United States, regardless of where you have the procedure performed. Vision insurance plans rarely cover refractive surgery. Some employers offer flexible spending accounts or health savings accounts that allow you to use pre-tax dollars for vision correction, which can reduce your out-of-pocket cost. International procedures at facilities like GS Eye Center are not eligible for insurance coverage in most cases. This is part of the value calculation when considering whether Seoul offers better overall value.

Conclusion

SMILE Pro and LASIK are both safe, effective vision correction procedures with nearly identical long-term visual acuity outcomes.
