Decided after detailed exam
Varies by case
Did you have LASIK or LASEK somewhere else, only to find your vision has blurred again — or that night glare and a leftover prescription make daily life harder than it should be? A LASIK/LASEK revision begins, above all, with finding out exactly why this happened. I re-examine your remaining corneal thickness and stability and the traces of the earlier surgery from the ground up, then tell you honestly whether there's a safe path back to clear vision. Even if another clinic told you it "can't be done," your options are well worth a second, careful look.
A dedicated revision center for patients whose vision declined or became uncomfortable after surgery elsewhere — delivering satisfying results with deep experience and precise equipment.

Is it right for me?
A good fit if
- Someone who had vision correction before, but whose prescription has crept back over time (regression) so they need glasses again
- Anyone bothered by night glare, starbursts, halos, or leftover astigmatism that makes driving and screen work uncomfortable
- Those who have struggled emotionally with an unsatisfying first surgery and want to work back through the cause, step by step
- People whose surgery was done abroad, making follow-up at home difficult, who want to consult in their own language with an interpreter
- Anyone who wants the full range considered — surface (LASEK) re-treatment or a flap-lift if the cornea allows, and ICL if it doesn't
Consider carefully if
- If the remaining cornea is too thin or its shape is unstable, I won't push for more reshaping. In that case we look first at alternatives that don't cut the cornea, such as ICL.
- If something compromises safety — suspected keratoconus, active dry eye, uncontrolled glaucoma — I stabilize that issue first, then reassess whether a revision is wise at all.
- Honestly, not every eye can be operated on again. When safety can't be assured, telling you plainly that "not having a revision is the better choice" is a principle I hold to.
1What a revision is, and how it differs from the first surgery
A revision (an enhancement or re-treatment) means working on an eye that has already been corrected once, so its very starting point differs from a first surgery. The cornea has been reshaped before; with LASIK there's the trace of a flap; and how much thickness remains varies enormously from person to person. That's why the key question isn't "which procedure" but "should this eye be touched again, and if so, how far." I read the method and result of the first surgery like a map, and design the safest single move on top of it.
2The detailed re-exam — why thickness, shape, and stability matter so much
It's no exaggeration to say eighty percent of a revision is decided in the exam. Corneal topography reveals subtle surface asymmetry and any sign of keratoconus; precise pachymetry calculates how much "room to reshape" is left. Only by looking three-dimensionally at pupil size, residual prescription, tear-film quality, and the real source of night glare does a safe plan emerge. To say it once more: carefully confirming the remaining corneal thickness and stability matters more than anything in a revision. A revision that skips this step is dangerous.
3The options — surface re-treatment, flap-lift, and ICL
There isn't one fixed method for a revision; it follows where the exam leads. If plenty of cornea remains, a LASEK-style surface re-treatment can be the clean choice; if a LASIK flap is in good shape, that flap can be lifted again for a fine adjustment. But when the cornea is too thin to reshape further, an ICL — placing a lens inside the eye without touching the cornea — is often the safest answer instead. What matters is not forcing one "right answer," but choosing together the safest road your eyes will allow.
4Safety first — knowing when not to operate is also skill
The most dangerous temptation in a revision is to "reshape it one more time, somehow." My principle is to proceed only within what's safely possible and to stop clearly when safety isn't assured. The more anxious you are after a poor result abroad, the more you need an honest diagnosis rather than glossy promises. So I won't be vague about "yes or no" or "this far is safe" — I'll tell you plainly. Sometimes "it's better not to operate" is the most responsible answer of all.
5For patients traveling from overseas
Because a revision's method and schedule depend on the exam results, planning the timeline matters especially for patients coming from abroad. Healing Eye is an MOHW-registered institution for international patients, with in-house Japanese, Traditional Chinese, and English interpreters, so we can honestly explain even a complex revision plan and its limits in your own language. We're right in front of Sinnonhyeon Station (a one-minute walk) and about 70 minutes from Incheon Airport, so getting here is easy. We guide you from arrival, and if you send your test records in advance, we can sketch a rough direction together before you fly in.
How the surgery goes
- 1
1. Reviewing your surgical history + detailed re-exam
I listen calmly to when and how you were operated on, then build a three-dimensional picture of your eyes today with topography, precise thickness measurement, and pupil and tear-film testing.
- 2
2. Cause analysis and feasibility decision
After distinguishing the cause — regression, residual prescription, or night glare — I judge whether the remaining cornea allows a safe re-treatment, and if so, how far.
- 3
3. Choosing the tailored method, explained fully
We choose the safest path together among surface re-treatment, flap-lift, or ICL, and I explain the expected benefit, the limits, and the recovery timeline without hedging. I won't recommend a forced revision.
- 4
4. Numbing drops, then the precise re-treatment
With numbing drops easing discomfort, I proceed precisely along the plan we set. The key correction step itself is usually brief, and I monitor your condition throughout.

5. Same-day check and recovery plan
Right after surgery I check the eye, then walk you through the recovery schedule and drop routine suited to your method. For overseas patients, we plan everything down to your departure date.
Recovery timeline
How it feels depends on the method. A flap-lift tends to recover faster, while a surface re-treatment can feel irritated for a few days. Keep to the prescribed drops and protection, and let your eyes rest fully.
Because it's a revision, I follow your progress with extra care. At the next-day check I confirm in person that the cornea is settling well, and you can ask anything you like, with an interpreter.
Your vision gradually sharpens, but stabilizing can take longer than after a first surgery, so regular checks matter. Even when you're back home, we follow your progress together through an interpreter so your care continues from afar.
So that you never go through a bad experience again, one dedicated surgeon takes consistent responsibility from cause analysis through surgery and aftercare. With the lifetime surgery guarantee, the same doctor watches over your eyes to the end, years down the road.
Why Healing Eye
The same doctor sees you from start to finish. One dedicated surgeon takes consistent responsibility for cause analysis, surgery, and aftercare, and the lifetime surgery guarantee means I watch over your eyes for the long run. For something as delicate as a revision, having one person who knows your eyes deeply stay beside you to the end makes a real difference.
You hear it honestly, in your own language. In-house Japanese, Traditional Chinese, and English interpreters mean you can clearly understand and decide on even a complex revision plan and its limits in your mother tongue. The more anxious you arrive, the more reassuring it is to communicate precisely, with no misunderstandings.
Being foreign never costs you more. Your exam and surgery fees are exactly the same as for Korean patients — no tourist markup. The precise figure depends on your exam and chosen method, so we lay it out transparently in your free consultation.
Experience you can trust, easy to reach. Dr. Kim Sun-young is a cornea, glaucoma, and cataract specialist, a former clinical professor at Catholic University's medical college and a member of ESCRS — and a Google 4.8 rating with 154+ reviews backs that trust. We're one minute from Sinnonhyeon Station and about 70 minutes from Incheon Airport, so even a long trip ends easily.

Frequently Asked Questions
I had surgery at another clinic — can I still get a revision?
Yes — many patients come to me after surgery elsewhere. But I can decide whether it's possible, and how, only after closely reviewing your prior surgery and remaining cornea. If you can, send your test records in advance, and start with a free consultation and detailed exam. Feel free to reach out on LINE or WhatsApp.
Is a revision riskier than the first surgery?
It's true that more caution is needed, since the cornea has already been reshaped once. So I weigh the remaining thickness and stability carefully, proceed only within what's safe, and stop clearly if safety can't be assured. Accurate cause analysis and experience are what reduce the risk. Come confirm your eyes' real options and limits honestly in a free consultation.
Does a revision also take a long time to recover?
It depends on the method. A flap-lift recovers relatively quickly, while a surface re-treatment feels irritated for a few days before gradually sharpening. A revision can take longer than a first surgery to stabilize, so regular checks matter. If you're coming from abroad, planning the schedule is especially important — we'll map it out in advance in a free consultation.
I was told my cornea is thin — can I still have a revision?
Even if reshaping the cornea further is difficult, it doesn't mean there's no path. An ICL — placing a lens inside the eye without touching the cornea — can actually be the safer answer, so if thickness is lacking we consider it together. In every case, though, confirming safety first with a detailed exam comes first. I'll give you the precise verdict after testing, in a free consultation.
How long do I need to stay in Korea?
The stay you'll need depends on the revision method chosen and how fast you heal, so it's hard to give one fixed answer. Usually you'll need to be in Korea through the exam, surgery, and next-day check, after which we can follow your progress together from afar via an interpreter. Send your records ahead and we'll outline a rough schedule on LINE/WhatsApp before you travel.
How much does a revision cost, and do foreigners pay more?
International patients pay exactly the same as Korean patients — no tourist markup. That said, a revision's cost varies with the exam results and the method chosen (surface re-treatment, flap-lift, or ICL), so I can only give you an honest figure after examining you. We lay it out transparently after a free consultation and exam, so please reach out on LINE/WhatsApp.
