| keratectomy | 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).

| keratectomy, photorefractive, excimer laser | A type of refractive surgery of the cornea to correct myopia and astigmatism, using an excimer laser. An excimer laser is a laser containing a noble gas, such as helium or neon, which is based on a transition between an excited state in which a metastable bond exists between two gas atoms and a rapidly dissociating ground state. The extremely precise laser light reshapes the surface of the cornea without making an incision. This procedure can reduce much higher degrees of myopia than radial keratotomy (keratotomy, radial), although it generally takes longer for vision to clear. (12 Dec 1998) |
