Keratotomy: From 1 Different Sources

Keratotomy, Radial

A now uncommon procedure in which radiating incisions are made in the cornea (up to, but not through, its innermost layer) to reduce myopia.

Radial keratotomy has been largely replaced by laser procedures, such as LASIK, which carry less risk of permanent damage to the eye.... keratotomy, radial

Arcuate Keratotomy

a curved incision made in the periphery of the cornea. It is usually performed in the region of greatest curvature of the cornea in order to flatten it and hence reduce *astigmatism.... arcuate keratotomy

Radial Keratotomy

an operation for short-sightedness (myopia). Deep cuts into the tissue of the cornea are placed radially around the outer two-thirds of the cornea; this flattens the curvature of the central part of the cornea and reduces the myopia. This procedure is now rarely performed, having been superseded by *excimer laser treatment.... radial keratotomy
