A laser that emits very concentrated light in the ultraviolet (UV) region of the spectrum. Excimer lasers are used, for example, in: Ophthalmology -- to vaporize part of the surface layer of the cornea and thus reshape the cornea to correct refractive errors from myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. Dermatology -- [..]

This is an ultraviolet laser used for correction of the corneal curvature for refractive surgery.

(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 [..]

An argon-fluoride laser that emits ultraviolet light that is emitted in pulses at a wavelength of 193 nm. The term Excimer comes from the concept of an energized molecule with two identical components or excited dimer (contracted to one word exci-mer). Each pulse of this his "cool" laser removes 1/4000 millimeter of tissue from th [..]

Laser energy produced by several rare gas- halide mixtures. The term excimer comes from the concept of an energized molecule with two identical components or excited dimer (contracted to one word exci [..]

Gas Lasers with excited dimers (i.e., excimers) as the active medium. The most commonly used are rare gas monohalides (e.g., Argon Fluoride, Xenon chloride). Their principal emission wavelengths are i [..]
