keratomileusis /ker·a·to·mi·leu·sis/ (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 exposed cornea is reshaped by the laser, and the flap is replaced, without sutures, to heal back into position.

Laser-assisted in-situ keratomileusis for treatment of myopia. (A), Creation of flap; (B), Laser ablation of the stromal bed, showing the area of tissue removal in blue; (C), flap replaced, with the central cornea flattened
ker·a·to·mi·leu·sis (k r  -t -m-l  s s)n. A procedure for the correction of the refraction of the cornea by removing a deep corneal lamella, freezing it, forming it to a new curvature, and then replacing it. |
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.
