LASIK vs LASEK: Which Is Better? (2026)

Is LASIK or LASEK better?

LASIK is better if you want fast, comfortable recovery and have healthy corneas of normal thickness. LASEK is better if your corneas are thin, you play contact sports or your job rules out a corneal flap.

Both use an excimer laser to reshape the cornea and correct myopia, hyperopia and astigmatism. They differ in how the surgeon reaches the tissue to be treated. That one difference drives everything else: pain, recovery time, flap risks and who qualifies. In Seoul, both cost about the same, so the choice should be made on your eyes, not on price. A detailed pre-op eye exam is what settles it.

How are LASIK and LASEK different?

LASIK lifts a hinged flap from the cornea and lasers underneath it; LASEK removes only the thin surface skin and lasers the surface.

In LASIK, a femtosecond laser (or, at a few clinics, a mechanical microkeratome) cuts a flap around 100–120 µm thick. The surgeon folds it back, applies the excimer laser and lays the flap back down, where it seals without stitches.

In LASEK, dilute alcohol (about 18–20%) loosens the epithelium, which is moved aside or removed before the laser is applied to the surface. A bandage contact lens protects the eye while new epithelium grows, usually over 3–4 days. LASEK is a close relative of PRK; see PRK vs LASEK for that comparison.

LASIK vs LASEK side by side

This table compares the two on the points patients ask about most.

Dollar figures are approximate at ₩1,350–1,400 per dollar; prices were checked in 2026. A 2024 Korean consumer guide put average prices at about ₩1.9M for LASIK and ₩1.6M for LASEK, both eyes, so LASEK is often slightly cheaper in practice.

How long do I need in Seoul for each?

Plan about 3–5 days for LASIK and about a week for LASEK, counting the exam, surgery and the checks before you fly.

A typical LASIK trip is exam on day 1, surgery the same or next day, a day-1 check and a final check a few days later. LASEK adds the wait for the surface to heal: the bandage contact lens usually comes out on day 3 or 4, and most surgeons want to see the eye again before a long-haul flight. Expect blurred vision and light sensitivity for much of that week, so book a hotel close to the clinic and avoid scheduling sightseeing. Stop soft contact lenses beforehand as your clinic directs. For timings, see flying after LASIK and the 3-day LASIK trip itinerary.

Do LASIK and LASEK give the same results?

For low to moderate myopia, yes. For high myopia, the evidence favours LASIK.

A 2014 systematic review and meta-analysis of 12 studies (about 780 LASEK and 915 LASIK eyes) found no significant differences in final refraction or uncorrected vision for low to moderate myopia. In moderate to high myopia, however, LASEK eyes had more haze and were more likely to lose a line of best-corrected vision at 12 months. Surgeons now often apply mitomycin-C during surface treatments to reduce haze, but the authors noted the evidence for this is still limited. If your prescription is very high, ask whether an ICL is a better fit; see options for high myopia.

What are the main risks of each?

LASIK's specific risks come from the flap; LASEK's come from the slower surface healing.

With LASIK, a hard blow to the eye can displace the flap even years later, and dry eye is common in the first months. With LASEK, the first days are painful, there is a small infection risk while the surface is open, and haze can blur vision if it develops. Both share the general risks of laser vision correction: glare and halos at night, under- or over-correction and, rarely, corneal ectasia. The FDA advises patients to understand these risks and avoid surgery if their prescription is still changing. Ask any clinic how it handles a displaced flap or delayed surface healing, and who you contact once you are home. Read more on LASIK side effects and follow-up care after returning home.

Who should choose which?

LASIK is usually the better fit if you:

• Have healthy corneas of normal thickness and a stable prescription
• Have only a short trip to Seoul or must be back at work quickly
• Want the least discomfort

LASEK is usually the better fit if you:

• Have thin or borderline corneas
• Box, do martial arts, play rugby or have a job with eye-impact risk
• Can rest for about a week and accept slower visual recovery

If you are dry-eye prone and want quick recovery without a flap, also look at LASEK vs SMILE. Your ophthalmologist's findings should always outweigh any general rule.

FAQ

Frequently asked questions

Which is safer, LASIK or LASEK?

Both are considered safe for suitable eyes. LASEK avoids flap complications, while LASIK avoids the painful, slower surface healing. Your corneal thickness and prescription decide which is safer for you.

Why does LASEK take longer to recover?

The surface epithelium has to regrow after LASEK, which takes about 3–4 days under a bandage lens. Vision then keeps sharpening for several weeks.

Is LASEK cheaper than LASIK in Korea?

Seoul price ranges overlap at about ₩1.5M–₩2.5M for both eyes, though LASEK is often slightly cheaper at the same clinic. Always confirm what the package includes.

Can I have LASEK if I was told I am not a LASIK candidate?

Often, if the reason was thin corneas. If the reason was keratoconus, an unstable prescription or eye disease, LASEK may not be suitable either.

Is LASEK the same as PRK?

They are very similar surface treatments. PRK removes the epithelium completely, while classic LASEK loosens it with alcohol first; recovery is comparable.
