Bottom line up front: LASIK, PRK, and SMILE all reshape the cornea to correct vision, but differ in technique, candidacy, and recovery timeline — the right one depends on your specific eyes, not just preference.
| LASIK | PRK | SMILE | |
|---|---|---|---|
| Technique | Creates a corneal flap, reshapes tissue beneath | Removes surface layer entirely, reshapes cornea | |
| SMILE | Small incision, no flap, tissue removed through the incision |
| Factor | LASIK | PRK | SMILE |
|---|---|---|---|
| Recovery speed | Fast — clear vision within 24–48 hours | Slower — several days to a week of discomfort | Fast, comparable to LASIK |
| Best candidates | Most patients with adequate corneal thickness | Thinner corneas, some contact sports considerations | Nearsightedness specifically; newer, more limited long-term data |
Why candidacy matters more than personal preference
Corneal thickness, prescription type, and specific eye anatomy determine which technique is actually appropriate — not every patient is a candidate for every option. This is determined during a pre-op evaluation, not chosen off a menu.

The Takeaway
Your specific eye anatomy determines which technique is appropriate — a proper pre-op evaluation, not personal preference, should drive this decision.
