laser
laser (lay-zer) n. a device that produces a very thin beam of light in which high energies are concentrated. In surgery, lasers can be used to operate on small areas of abnormality without damaging delicate surrounding tissue. For example, they are used in eye surgery for cutting tissue (
YAG l.), for photocoagulation of the retina (
argon l.,
diode l.), and in operations on the cornea for correcting long- or short-sightedness (
excimer l.). Lasers are also used to unblock coronary arteries narrowed by atheroma, to remove certain types of birthmark (see
naevus), in the treatment of cervical intraepithelial neoplasia (see
CIN) and varicose veins (
endovenous l. treatment), and in a specialized form (
Nd:YAG l.) for some gynaecological procedures.
