How is LASEK different from LASIK?
LASEK laser eye surgery and LASIK laser eye surgery differ in the part of the eye that is removed in order to reshape the cornea. In LASIK laser eye surgery, a flap is made that cuts through the epithelium layer, and into the stroma part of the eye. In LASEK laser eye surgery, the epithelium layer is loosened and removed so that the cornea can be shaped, then it is replaced.
