1 Answer

The three refractive procedures differ only slightly - with PRK, Mr Bailey uses an excimer laser to reshape the surface of the cornea after removing the thin superficial skin of the eye. When performing LASEK or epi-LASIK surgery, however, the superficial skin is removed, set aside and is replaced at the end of the procedure. Either way, a new superficial skin regenerates in a few days. more
