keratomileusis

keratomileusis /ker·a·to·mi·leu·sis/ (ker?ah-to-mi-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
