Every year, patients fly to Seoul for LASIK after reading glowing reviews online — and some of them aren't actually good candidates once we examine their eyes. Here's what I tell patients before they book a flight, not after.

How to actually choose a clinic
I'm Dr. Baek Dong-won, Representative Director at EYEONCE Eye Clinic in Gangnam, Seoul. Over the years I've operated on patients who flew in from the US, the Middle East and across Asia specifically for LASIK — and the reason is rarely just one thing. Korea has an unusually high concentration of refractive-surgery clinics in a small area of Seoul, which means intense competition on both technology and outcomes. For an international patient, that translates into access to current-generation laser platforms and surgeons who perform these procedures often, combined with an English-speaking patient journey that doesn't require guessing at a language barrier mid-consultation.
That said, "popular destination" isn't the same as "right for you." The decision that actually matters happens at the exam table, not in a review thread — which is the part I want to walk through honestly below.
This is the question I'd answer first, before anything about technology or price. LASIK candidacy comes down to a handful of measurable things: your prescription (degree of myopia, hyperopia or astigmatism), your corneal thickness, your pupil size, and whether your eyes show any signs of keratoconus or significant dry eye. None of that can be assessed from a photo of your glasses prescription or a phone call — it needs a proper diagnostic work-up with corneal topography and thickness mapping.
What I see most often in international patients is one of two situations: either they assume they qualify because a friend had great results, or they assume they don't qualify because a clinic back home told them "no" years ago when the technology was more limited. Both assumptions are worth re-checking with current equipment before you rule yourself in or out.
At EYEONCE we perform all three laser-based paths — LASIK and LASEK on the WaveLight EX500 excimer laser, and SMILE LASIK as a flapless, keyhole alternative on the Ziemer FEMTO Z8 femtosecond platform. Neither is categorically "better" — they solve for different corneas. LASIK's flap approach tends to give the fastest visual recovery for patients with suitably thick corneas. SMILE LASIK's flapless technique preserves more of the cornea's structural layers, which can matter for certain prescriptions or lifestyles. LASEK trades a slower recovery curve for suitability in thinner or more irregular corneas where a flap isn't the safest choice.
If your topography shows high myopia with a cornea too thin for any of the three, that's not the end of the conversation — it usually means ICL (implantable lens) surgery is the better-suited option, and I'd rather tell you that at the exam than perform a laser procedure your eyes aren't a safe fit for.
For LASIK, most patients notice meaningfully clearer vision within a day, with a next-day check-up confirming healing is on track before travel. SMILE LASIK follows a similar early timeline. LASEK is different — vision improves more gradually over the first one to a few weeks as the corneal surface heals, so if LASEK turns out to be your path, we build your travel schedule around that, not around LASIK's faster curve.
Either way, don't book a one-way return flight for the morning after surgery. A short buffer for the next-day check matters more than shaving a day off your trip.
Dry eye sensation and some light glare or halos at night are the most common temporary effects after any laser vision correction, including LASIK. They're not failures of the surgery — they're part of how the cornea heals, and for most patients they settle within the first one to three months. We reduce the risk going in by screening for pre-existing dry eye and pupil size at the diagnostic stage (not deciding that after surgery), and we manage it coming out with prescribed drops and a clear, written aftercare schedule rather than a verbal "you'll be fine."
If symptoms are unusually severe or don't settle on the expected timeline, that's exactly when you should reach out — which brings us to what happens after you've already flown home.
This is the part of medical travel patients worry about most, and I think they're right to. Our answer is EYEONCE's lifetime aftercare commitment: if anything ever seems wrong after your surgery, you can contact us at any time, from anywhere. We'll go through a detailed re-examination (by video, by your local records, or in person if you can return) and, where appropriate, guide you through re-treatment. It doesn't disappear once your flight takes off.
In practice this usually means coordinating with you and, if useful, with a local ophthalmologist near you, rather than insisting you fly back to Seoul for every follow-up question.
If you are comparing countries, LASIK in Korea vs Singapore: what really differs covers follow-up in more detail.
Past the marketing, three things are worth checking directly: who reviews your diagnostic results and who operates — ideally the same person, which is how we run things at EYEONCE through our medical team; whether English-speaking staff are actually on-site rather than a translated brochure; and whether aftercare is explicitly a long-term commitment rather than something that ends at your airport departure. Ask these three questions of any clinic you're considering, including us — the answers should be specific, not reassuring-sounding.
Every patient's eyes are different. Candidacy for LASIK, SMILE LASIK, LASEK or ICL — and the recovery timeline that follows — can only be confirmed through an in-person (or video) consultation and a full pre-operative diagnostic exam with our team. Nothing in this article replaces that exam.
