Best SMILE LASIK in Korea? 5 Questions I'd Ask Any Clinic

Hello, I'm Dr. Kim Sun-young, Medical Director of Healing Eye Clinic, one minute on foot from Sinnonhyeon Station in Gangnam, Seoul. I was a clinical professor of cornea and cataract at Uijeongbu St. Mary's Hospital, and I now see patients who fly in every week, with an English interpreter on site.

A question we often get on WhatsApp goes like this: "Dr. Kim, which clinic does the best SMILE LASIK in Korea?" If you typed something close to that, you're probably comparing five tabs of clinics that all look the same. I understand. You get one pair of eyes, and you're about to trust them to a city you may have visited only once.

So let me be honest first. There is no "best SMILE LASIK in Korea" for everyone, only the right plan for your cornea, done by a surgeon who will also tell you no. What I can give you is the list of questions I'd ask if I were the one flying in, in the order I explain things in the consultation room.

Why "best SMILE LASIK in Korea" is the wrong search

Rankings measure what's easy to count: ads, star ratings, how loud the price looks. They don't measure the things that decide how your eyes do in five years.

SMILE is a small-incision laser procedure. A femtosecond laser shapes a thin lens of tissue, called a lenticule, inside the cornea, and the surgeon removes it through one small opening. There is no flap to lift. That is the appeal, and it's also why the surgeon's judgment matters so much: the question is whether your cornea is a good fit at all.

Here are the five questions I'd ask any clinic, including mine.

1. Which laser do you use, and will you name it?

A clinic should tell you the platform without hesitation. Ours is the Ziemer FEMTO LDV Z8, and we call the procedure Clear SMILE LASIK, a third-generation small-incision method.

Think of it like asking a pilot which aircraft you're flying on. The name alone doesn't make the flight safe, but a vague answer tells you something. If the brochure lists only a marketing name and nobody can tell you the machine behind it, ask again.

2. Who examines me, and who operates?

Ask for a name, not "our medical team". Ask whether the same doctor examines you, operates, and sees you the next morning.

Here, one dedicated doctor stays with you from the exam to surgery to aftercare. I prefer it that way because the person holding the laser should be the person who looked at your corneal map and worried about it.

3. What does the exam measure, and can it end in "no"?

A real exam measures corneal thickness, the shape of the cornea on a topography map, your prescription and how stable it has been, and the state of your tear film. Those four decide whether SMILE stays on the table.

If a clinic quotes you a surgery date before seeing any of that, slow down. The candidate qualifications for SMILE LASIK in Korea lists what usually rules people in or out.

4. What happens the morning after, and after I fly home?

The first check-up is the next day, in Seoul, before you board anything. With Clear SMILE LASIK, the scheduled checks are at one day, one week, one month and within the first year.

Since most of those happen at home for overseas patients, ask what you leave with. We give you a written record: the procedure, your prescription, the amount of tissue removed, corneal thickness and the drops you're using. An eye doctor at home can pick up from there.

5. Is the price written down, and is it the same for everyone?

You should see one number for both eyes, with the exam listed separately, before you book flights. At Healing Eye Clinic, international patients pay the same price as Korean patients, with no foreigner surcharge.

If a quote changes every time you message, or a "today only" discount appears, ask what exactly is included. How to compare SMILE LASIK quotes in Korea goes through that line by line.

Why I think the doctor who says "no" is the one to trust

I'd rather lose a booking than operate on a cornea I'm not comfortable with. That isn't modesty. A thin or irregular cornea treated with the wrong method is a problem that follows a patient for decades.

Since you can't sit in my room before you decide, here is what you can check from home. I share it as evidence, not as a boast. Healing Eye Clinic holds 4.8 out of 5 on Google reviews. I'm a full member of ESCRS, the European Society of Cataract and Refractive Surgeons, and the clinic is registered with Korea's Ministry of Health and Welfare to treat international patients. We also run a LASIK and LASEK revision center and a lifetime surgery responsibility guarantee. Our Korean-language Clear SMILE LASIK page describes the procedure for local patients, and a translation app handles it well.

For a wider view of how I judge clinics, what a Seoul surgeon checks first for SMILE LASIK in Korea covers the three things I look at before saying yes.

So is SMILE right for me, or something else?

The exam decides, not the brochure. This is roughly how the conversation goes once I have your numbers.

These are our published prices for both eyes. The full list is on our price page.

Side effects, and who I'd ask to wait

SMILE is gentle on the surface, but it is still surgery on the cornea. Here is what I tell every patient.

• Dryness is common in the first weeks, and airplane cabins make it worse. Artificial tears help.
• Glare or halos around lights at night can appear while the cornea settles.
• Regression, a slow drift back of the prescription, can happen over time.
• Under- or over-correction and inflammation at the incision are less common, and some need drops or further treatment.

How fast vision settles differs from person to person. I'd ask you to wait if your prescription changed in the past year, if you're pregnant or breastfeeding, or if severe dry eye needs treating first. A thin or irregular cornea usually means a different method, not a riskier SMILE.

Planning the trip to Seoul

• Stop contact lenses before the exam: soft lenses one week, hard lenses three weeks.
• Shortest stay: two days. Exam in the morning, surgery in the afternoon if the results allow, check-up the next day. Two to three days is more relaxed.
• Flying: from the day after surgery, once the check-up looks fine. Keep artificial tears in your pocket.
• After surgery: washing your face and showering resume after the next-day check. Light jogging is fine from the next day, swimming from two weeks, ball sports from one month.
• Getting here: about 70 minutes from Incheon Airport, one minute from Sinnonhyeon Station.

If you're still deciding on travel dates, choosing a Clear SMILE LASIK clinic around your flight schedule walks through which weekday surgery should land on.

Don't book the surgery yet — book the exam

Please don't choose a clinic by the lowest number or the loudest ranking. Choose the one that answers the five questions clearly and lets the exam have the final word.

Send a photo of your current prescription on WhatsApp and ask me one question about your own eyes. The consultation is free. If your eyes aren't right for SMILE, or for surgery at all right now, we'll tell you that directly.

I look forward to examining your eyes in Seoul.
