| excimer laser |
The term excimer comes from the combination of excited and dimer. The excimer laser was developed in the late seventies and has output in the ultraviolet and near ultraviolet region. In an excimer laser a noble gas such as krypton, Kr, or xenon, Xe, is excited in the presence of a halogen such as fluorine, F, or chlorine, Cl, and neon, Ne, or helium, He, in a resonant cavity. A high voltage pulse dissociates electrons from the noble gas molecules creating a plasma. ...

(EKS-ih-mur). Class of ultraviolet lasers that removes tissue accurately without heating it. In refractive corneal surgery, controlled by computer to make precise pre-programmed shavings of eye tissue to produce a given optical correction. Used for photorefractive keratectomy (PRK); combined with automated lamellar keratoplasty (ALK) to produce LASIK (laser in situ keratomileusis).

The Excimer laser is perhaps the best known of all lasers because of its use in laser vision correction surgery such as laser in-situ keratomileusis (LASIK) and photorefractive keratectomy (PRK). The Excimer, or pulsed gas laser, emits an ultraviolet light beam, vaporizing tissue by breaking down molecular tissue bonds in a minute targeted area. It is called a cold laser because it doesn't produce heat that could have harmful effects to the surrounding tissue.

a laser with rare gas halides as the active medium whose beam is in the ultraviolet spectrum and penetrates tissues only a small distance; the beam breaks chemical bonds instead of generating heat to destroy tissue. Used in ophthalmological procedures and laser angioplasty.
