A confusing fact for refractive surgery patients is the relationship between PRK and LASIK. PRK is performed on every patient who has LASIK. PRK (Photorefractive Keratectomy) simply refers to the laser beam that reshapes your cornea.
The first step in
LASIK surgery involves an instrument called a microkeratome which automatically cuts a small flap on the cornea. This flap is then lifted and the cornea is reshaped by performing PRK. The flap is then laid down and heals overnight. If you have a thin cornea or an abnormal shape to the cornea you may have PRK performed without making the flap. You will end up with the same result but you will have increased healing time (3-10 days on the average) and increased pain which will be controlled by pain medications. No pain medication is required for the post-op period after LASIK.
During the PRK procedure, the excimer laser beam removes tissue directly on the cornea. This is compared to LASIK where the PRK procedure is performed after the flap is made and lifted back. Again, you will end up with the same result as with LASIK.
