The abbreviation for laser-assisted in-situ keratomileusis, a type of eye surgery in which a laser is used to reshape the cornea to correct refractive errors (see refraction) such as shortsightedness (see myopia) and astigmatism.
Acronym for laser in-situ keratomileusis, which is a variety of surgery of the EYE used to correct severe myopia (short-sightedness – see REFRACTION; EYE, DISORDERS OF). A thin ?ap of the cornea is lifted, the area underneath reshaped using an EXCIMER LASER, and the ?ap is then returned to its place, the altered contour of the cornea improving the patient’s sight.
laser in situ keratomileusis: laser refractive eye surgery used to correct both *myopia (short sight) and *hypermetropia (long sight). A thin corneal flap (epithelium and stroma) is raised using a keratome, the cornea is reshaped using an *excimer laser, and the flap is then replaced. Compare intrastromal keratomileusis.
A type of laser that is used to remove thin sheets of tissue from the surface of the cornea (see EYE), thus changing the curvature of the eye’s corneal surface. The procedure is used to excise diseased tissue or to correct myopia (see REFRACTION), when it is known as photorefractive keratectomy or lasik.... excimer laser
an operation to correct severe degrees of myopia (short-sightedness). A disc of corneal tissue (from the *stroma of the cornea) is removed, frozen, and remodelled on a lathe, then replaced into the cornea to alter its curvature and thus reduce the myopia. *Excimer laser treatment, which is easier to perform, has now replaced this (see LASIK).... intrastromal keratomileusis
any surgical procedure that has as its primary objective the correction of any refractive error. It includes such procedures as clear lens extraction, *LASIK, *LASEK, and photorefractive *keratectomy.... refractive surgery
