Keratomileusis, from Greek κέρας (kéras: horn) and σμίλευσις (smíleusis: carving),[1] orcorneal reshaping, is the improvement of therefractive state of thecornea by surgically reshaping it. It is the most common form ofrefractive surgery. The first usable technique was developed byJosé Ignacio Barraquer, commonly called "the father of modern refractive surgery."[2]
The most common modern procedure,LASIK, is performed through lifting the front surface of theeye by forming a thin hinged flap under which the shape of the cornea is changed by using anexcimer laser or other surgical device. Amicrokeratome is usually used to cut the flap, but afemtosecond laser can also be used to make the flap.[citation needed]
Before the advent of the excimer laser, keratomileusis was done using acryolathe, which froze thin flaps of corneal tissue and lathe cut them much like one cuts the lens of a pair of glasses. After thawing, these reshaped flaps were placed under the front flap to reshape the cornea.[citation needed]
