PRK

PRK (Photo Refractive Keratectomy) is the Eximer Laser correction of nearsightedness, astigmatism, and farsightedness, which reshapes the front surface of the cornea. PRK differs from LASIK in that it does not require an incision to form a corneal flap. No cutting is involved. After PRK a bandage soft contact lens is placed over the eye for 2 to 3 days to allow the corneal epithelium to regenerate over the remolded front surface of the eye. Improved vision is usually achieved after 3 to 6 days of healing. PRK, together with LASIK, is considered by nearly all experienced refractive surgeons in the world to be the procedure of choice in correcting vision problems.

The visual results of PRK and LASIK are comparable for corrections up to about 8 diopters of nearsightedness.

Doctors J.Simone, Badeen, and Kwapiszeski have been performing PRK laser surgery since the FDA approved the procedure in 1995.
