keratectomy

[ker″ah-tek´to-me]

excision of a portion of the cornea; kerectomy.

photorefractive keratectomy a procedure to correct errors of refraction in the eye by using an excimer laser to remove a portion of the anterior part of the cornea, which changes the refraction by creating a new radius of curvature.

ker·a·tec·to·my

(ker'ă-tek'tŏ-mē),

An operation done to change the refraction of the cornea; a crescentic piece of corneal stroma is removed and the resultant corneal wound is sutured. This steepens the cornea and increases its power in that axis.
See also: keratotomy.

[kerato- + G. ektomē, excision]

Two types of laser surgery-photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK)-are often used to correct refractive errors such as nearsightedness.
