keratectomy (medicine)


keratectomy
<procedure> 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.

Origin: kerato-+ G. Ektome, excision

Photorefractive keratectomy, removal of part of the cornea with a laser to change its shape, and thus to modify the refractive error of the eye (reduce its myopia, for example).
