PRK

Not all patients are good candidates for LASIK surgery.

For patients whose corneas are too thin or who have other conditions, other options are PRK (photorefractive keratectomy), LASEK (laser epithelial keratomileusis) or Epi-LASIK surgery.

During these procedures, the laser treatment is done directly on the surface of the cornea after removing a small amount of the outer layer of cells.

The PRK procedure can be done to correct nearsightedness (myopia), farsightedness (hyperopia), or astigmatism.
