Epi-LASIK is a modified PRK procedure where a corneal scratch is not made unlike PRK...this procedure saves the skin layer of the eye called the "EPI"thelium to potentially promote a faster healing rate with the skin surface preserved. After PRK laser vision correction with Doctor William Columbus, a bandage contact lens is kept in the eye for one week protection and to facilitate healing with eyedrops. Vision usually occurs to its fullest within just several days afterwards. Like PRK, this procedure is safest for THIN CORNEAS. BOTH procedures PRK & EPI-LASEK avoid typical LASIK flap complications as these procedures are "FLAPLESS" procedures best suited for thin corneal patients.
