LASEK in Gangnam, Seoul, Korea — flap-free surface laser correction
LASEK reshapes the surface of the cornea without cutting a flap, preserving more corneal tissue. It is often the safest laser option for thinner corneas, contact-sport athletes and people in high-impact jobs.

What is LASEK and who is it best for?
LASEK is a flap-free laser vision correction that reshapes the corneal surface after the thin outer layer (epithelium) is moved aside; the epithelium then regrows in a few days. It is often recommended for thinner corneas and contact-sport athletes. Apgujeong Eye Clinic in Gangnam, Seoul, Korea offers LASEK with board-certified ophthalmologists and English-speaking aftercare.
- Flap
- None
- Treats
- Myopia, hyperopia, astigmatism
- Discomfort
- 2–3 days
- Stable vision
- About 1–3 months
Preserving corneal strength for thinner corneas
Instead of a flap, LASEK treats the very surface of the cornea. The epithelium — the cornea’s skin-like top layer — is loosened and moved aside, the excimer laser reshapes the tissue beneath, and a soft bandage contact lens is placed while new epithelium grows back over 3–5 days.
Because no flap is created, more of the cornea’s structural strength is preserved and there is no risk of flap displacement. The trade-off is a slower, less comfortable first week compared with LASIK or SMILE.
- No flap — suitable for many thinner corneas
- No risk of flap displacement from impact
- Treats myopia, hyperopia and astigmatism
- Long-term visual results comparable to LASIK
Who is a good candidate for LASEK?
Final eligibility is confirmed only after a full diagnostic exam with your surgeon.
Usually a good fit if you…
- Have corneas too thin for LASIK
- Do contact sports, martial arts or military/police work
- Have a stable prescription for at least a year
- Can allow a few days of downtime after surgery
- Have a corneal shape unsuitable for a flap
We may suggest another option if…
- You need to be back at work in 1–2 days — SMILE or LASIK may suit better
- Your corneas show keratoconus — cross-linking or ICL may be considered
- Your myopia is very high — EVO ICL may be safer
- You are pregnant or breastfeeding
- You have active eye infection or severe dry eye
Your LASEK recovery timeline
Day 0
Surgery takes about 15 minutes; a bandage lens is placed on each eye.
Days 1–3
Light sensitivity and watering are common; prescribed drops and rest help.
Days 4–5
Bandage lens removed at the clinic; vision improves noticeably.
Weeks 1–4
Vision continues to sharpen; most return to normal activities.
Months 1–3
Vision stabilises; follow-up checks confirm the final result.
LASEK vs LASIK vs SMILE
Each option balances recovery speed against corneal preservation.
| LASEK | LASIK | SMILE | |
|---|---|---|---|
| Flap | None (surface) | Yes | None (2–4 mm incision) |
| Corneal strength preserved | Highest | Lower | High |
| Visual recovery | 5–7 days | About 1 day | 1–3 days |
| Discomfort | Moderate for 2–3 days | Minimal | Minimal |
| Contact sports | Excellent | Less ideal | Good |

Frequently asked questions
Is LASEK more painful than LASIK?
LASEK causes more discomfort in the first 2–3 days while the surface heals — typically light sensitivity, watering and a gritty feeling. Prescribed drops and the bandage lens help.
How long do I need to stay in Korea for LASEK?
Plan about 7 days so the bandage lens can be removed at the clinic and your surface healing checked before you fly.
Is LASEK the same as PRK?
They are closely related surface treatments. In PRK the epithelium is removed; in LASEK it is loosened and repositioned. Both avoid a flap.
Are LASEK results as good as LASIK?
Long-term visual outcomes are comparable. LASEK simply takes longer to reach its final sharpness.
Can LASEK treat astigmatism?
Yes. LASEK can correct myopia, hyperopia and astigmatism within safe limits set by your corneal measurements.
