Keratomileusis, from Greek κέρας (kéras: horn) and σμίλευσις (smileusis: carving)[1], or corneal reshaping, is the surgical improvement of the refractive state of the cornea by surgically reshaping it. It is the most common form of refractive surgery. The first useable technique was developed by José Ignacio Barraquer, commonly called "the father of modern refractive surgery."
