Dr. Zweibel describes the difference between PRK and LASIK surgery as well as the similarities. During LASIK surgery, a flap is created and lifted up while the cornea is reshaped, before it's put back into place. If the cornea is very thin or a very large correction is going to be performed, patients may benefit more from PRK. PRK recovery is slightly slower, but the overall result is often similar.
