LASIK and PRK are both laser vision correction procedures that reshape the cornea to reduce glasses dependence. They differ mainly in how the surface layer is handled and how recovery feels.
Key procedural differences
In LASIK, a flap is created then lifted so the laser can treat the underlying tissue. PRK removes the surface layer instead, which then regrows.
- LASIK usually offers quicker visual recovery and less early discomfort
- PRK avoids a flap, which may suit thinner or more irregular corneas
- Both use similar laser technology to correct short-sight, long-sight, and astigmatism
- Suitability depends on corneal thickness, prescription, and lifestyle
Recovery and long-term outcomes
Long-term results are similar for many patients, with high satisfaction rates. Recovery experience and risk profile differ slightly.
- LASIK patients often return to normal activities within a few days
- PRK involves more discomfort for several days and slower visual improvement
- Risk of flap complications is unique to LASIK, while PRK has more early haze risk
- Your surgeon will discuss which option best balances safety and expectations
