Epi-LASIK in Korea: Cost, Candidacy & Recovery

What is Epi-LASIK?

Epi-LASIK is a surface laser procedure that sits between LASEK and LASIK. A device called an epikeratome, which uses an oscillating blunt plastic blade, separates the outer epithelial layer as a thin hinged sheet; the excimer laser then reshapes the cornea underneath.

Unlike LASIK, no deep stromal flap is cut, so the cornea keeps more of its strength. Unlike LASEK, no alcohol is used to loosen the epithelium. Review of Ophthalmology, reporting early experience, noted that the separated epithelium appeared intact under the microscope and that surgeons could convert to PRK if a sheet was incomplete. Afterwards the sheet is either laid back or removed, and a bandage contact lens protects the eye while new epithelium grows.

Is Epi-LASIK still offered in Seoul?

Only at a minority of clinics. Most Seoul refractive centres now offer conventional LASEK, PRK or all-laser surface treatment such as Trans-PRK, which removes the epithelium without any instrument. If a clinic advertises Epi-LASIK, ask which device it uses and how many cases it performs each year; low volume can matter for a technique with a learning curve.

How does Epi-LASIK compare with other surface procedures?

Results at six months are broadly similar across surface methods; the differences are in early comfort and healing.

The mixed findings explain why many Korean surgeons moved on. For the broader choice, compare LASIK vs LASEK and PRK vs LASEK in Korea.

Should I ask for Epi-LASIK or accept another surface method?

For most people the honest answer is that the surface technique matters less than the surgeon and the measurements. Epi-LASIK, LASEK, PRK and Trans-PRK all leave no stromal flap, and studies show they reach similar vision after a few months. What differs is how the epithelium is removed and therefore how the first week feels.

If a Seoul clinic recommends LASEK or all-laser treatment instead of Epi-LASIK, that is usually because it is the method its surgeons perform most often, which is a reasonable basis for choice. What you should insist on is a clear explanation of your corneal thickness, topography and the planned ablation depth, and a written plan for follow-up after you return home. If your exam shows an irregular cornea or early keratoconus, any laser vision correction may be inappropriate, and the clinic should say so.

Epi-LASIK is sometimes confused with LASIK because of the name, but recovery is much closer to LASEK. Do not book a tight itinerary on the assumption that you will see sharply the next morning.

How much does Epi-LASIK cost in Korea?

Where it is available, Epi-LASIK is priced like other surface procedures: about ₩1.3 million to ₩2.5 million for both eyes, approximately $950–$1,900 at roughly ₩1,350–₩1,400 per dollar. We could not find a current published Epi-LASIK price from a Seoul clinic, so treat this as a guide and ask for a written quote for both eyes. Packages typically include the pre-op exam, surgery, bandage lenses, drops and early follow-ups; see LASEK cost in Korea for typical inclusions.

Also confirm what happens if the epithelial sheet does not separate cleanly and the surgeon converts to PRK during surgery: the price should not change, but it is worth hearing that in writing. Ask, too, whether extras such as serum eye drops, corneal strengthening or an enhancement within a set period are included, because these optional items are where Seoul quotes differ most.

Who is a candidate?

Epi-LASIK suits the same people as other flap-free surface treatments.

• Low to moderate myopia or astigmatism with a stable prescription
• Thinner corneas where LASIK would leave too little tissue
• Contact sports or jobs with risk of eye injury
• Some patients with dry eye, where avoiding a flap may help

Steep corneas can make the epikeratome harder to use, and it is not used for keratoconus. Our candidacy guide explains the tests.

What is recovery like?

Recovery is similar to LASEK and slower than LASIK.

Plan 5–7 days in Seoul. See our LASEK recovery and pain guide for practical tips.

What are the risks?

Possible problems include incomplete epithelial separation (requiring conversion to PRK), early pain, corneal haze, infection while the surface heals, dry eye, and under- or over-correction. This page is general information only; have a full exam and follow your ophthalmologist's advice.

FAQ

Frequently asked questions

Is Epi-LASIK the same as LASEK?

Both lift the epithelium as a sheet without cutting a stromal flap. LASEK uses alcohol to loosen it; Epi-LASIK uses a blunt mechanical epikeratome.

Is Epi-LASIK less painful than PRK?

Studies disagree. One Nepalese series found less pain, while a Seoul study from Asan Medical Center found more pain on day 4 than PRK.

Why don't many Korean clinics offer Epi-LASIK?

Results were not clearly better than LASEK or PRK, and all-laser Trans-PRK now offers a no-touch alternative. Most clinics have shifted to those.

How long does Epi-LASIK take to recover?

The surface usually heals in 3–5 days, and vision settles over 1–3 months.

Is Epi-LASIK good for thin corneas?

It preserves more tissue than LASIK, so it can suit thinner corneas. Final suitability depends on your full corneal scans.
