LASIK
A corneal-flap procedure known for relatively fast recovery
LASIK
- LASIK creates a corneal flap, reshapes the tissue underneath with a laser, and repositions the flap.
- Because the flap re-adheres naturally, eye-rubbing and strong impact should be avoided during early recovery.
- Many patients resume daily activities within a few days.
- Generally considered when corneal thickness is sufficient.
LASIK creates a thin corneal flap, reshapes the tissue underneath with a laser, then repositions the flap to heal in place. Because the flap needs time to naturally re-adhere, patients are advised to avoid rubbing the eye or strong impact right after surgery — but many are able to resume daily activities within a few days. LASIK is generally considered when the cornea is sufficiently thick.
How much does it cost?
roughly 1,000,000–2,000,000 KRW for both eyes
Checklist for choosing a clinic
- Flap-creation equipment — Ask what equipment is used to create the flap (femtosecond laser vs. microkeratome) and how precision is verified.
- Corneal thickness exam — Confirm the pre-op exam properly calculates residual corneal thickness after the flap is created.
- Flap aftercare guidance — Ask for specific guidance on activities to avoid while the flap is stabilizing.
- Aftercare coverage — Confirm whether follow-up visits and rechecks are included in the quoted price.
Frequently Asked Questions
What should I be especially careful about after LASIK, regarding the flap?
Since the corneal flap re-adheres naturally, you should avoid rubbing your eyes or exposing them to strong impact during early recovery. Wearing protective eyewear and following your surgeon's recovery schedule helps prevent the flap from shifting.
What's the biggest difference between LASIK and LASEK?
LASIK creates a flap, reshapes the tissue underneath, and repositions the flap; LASEK removes only the surface epithelium with no flap at all. LASIK recovery is often faster, while LASEK carries less flap-related risk and can be an option when the cornea is thinner.
How long does LASIK recovery take?
Many patients resume daily activities within a few days, though full flap stabilization can take longer. Recovery speed varies with individual corneal condition, so follow your surgeon's guidance closely.
Are there cases where LASIK isn't possible?
If corneal thickness is insufficient for flap creation, or specific conditions such as keratoconus or severe dry eye are present, LASIK may not be recommended. In these cases, LASEK, SMILE LASIK, or other options are typically considered instead.
