Medical term:
keratomileusis
keratomileusis
[ker″ah-to-mĭ-loo´sis]keratoplasty in which a slice of the patient's cornea is removed, shaped to the desired curvature, and then sutured back on the remaining cornea to correct optical error.
laser-assisted in-situ keratomileusis (LASIK) keratoplasty in which the excimer laser and microkeratome are combined for vision correction; the microkeratome is used to shave a thin slice and create a hinged flap in the cornea, the flap is reflected back, the exposed cornea is reshaped by the laser, and the flap is replaced, without sutures, to heal back into position.

ker·a·to·mi·leu·sis
(ker'ă-tō-mī-lū'sis),Surgical alteration of refractive error by changing the shape of a deep layer of the cornea: the anterior lamella is peeled back, frozen, and recarved on its back surface on a lathe; some of the corneal stroma can be removed from the bed with a laser or a knife.

keratomileusis
(kĕr′ə-tō-mə-lo͞o′sĭs)n.
Eye surgery in which refractive disorders are corrected by reshaping an inner layer of the cornea, formerly performed by freezing corneal layers and forming them to a new curvature, but now usually performed using a laser.

keratomileusis
A surgical procedure on the cornea aimed at correcting ametropia. An anterior layer of the cornea is sliced off with a microkeratome, frozen, ground to a new curvature and sutured back in the same location. There are many complications and technical difficulties associated with this procedure. Syn. refractive keratoplasty and keratorefractive surgery (both terms also include epikeratoplasty, keratophakia and radial keratotomy). See epikeratoplasty; Intacs; photorefractive keratectomy; keratome; keratophakia; LASEK; LASIK.
