PRK and LASIK are both effective surgical procedures for correcting nearsightedness, astigmatism, and farsightedness. The top layer of cells are removed using PRK exposing the treatment area, while LASIK involves making a flap from these cells to expose the area. The end results are very similar, it’s just a matter of how and when they are achieved.
- PRK has a higher risk of residual cornea haze though the rate is still very low.
- There is less discomfort after LASIK
- The final result is quicker with LASIK
- Less postoperative drops are usually required for LASIK
