Surgical Options
Radial Keratotomy- 4 to 8 corneal incisions are made involving 95 to 99% of corneal thickness, to flatten the central cornea. Excimer laser photorefractive keratectomy (PRK) - removes 10-20% of the superficial corneal tissue, centrally. It thus weakens the cornea less than radial keratotomy.
