(Tıp) excimer laser
A laser which is used to pump another laser, usually dye, laser
The excimer laser is the actual device that is used in many vision correction procedures It is a cool laser that changes the shape of the cornea by eliminating tissue
The ultraviolet laser used to remove corneal tissue during refractive surgery
an ultraviolet laser used in refractive surgery to remove corneal tissue
A high-energy, cold laser that is used in the Photorefractive Keratomy (PRK) and Laser In-Situ Keratomileusis (LASIK) procedures to sculpt the central zone of the cornea to correct nearsightedness, farsightedness or astigmatism Guided by a computer under the direction of an ophthalmologist, the laser emits a pulsating beam of ultraviolet light that ablates, or vaporizes, the corneal tissue to the precise depth and area required for refractive vision correction See Laser In-Situ Keratomileusis (LASIK), Refractive Surgery, and Photorefractive Keratomy in the Eye Care Encyclopedia
Non-thermal "cool" unltraviolet laser (argon-flouride type) used for refractive surgery The laser is capable of etching or reshaping corneal tissue with great precision
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 the targeted surface by breaking intra molecular bonds in collagen molecules It would take about 200 pulses from an Excimer laser to cut a human hair in half This laser was originally developed for use in the microprocessor industry and later found its application in vision correction
(laser_ad_eccimeri, laser_ad_eccimeri html) • Refractive corneal surgery is generally undertaken in order to modify the optical power of the cornea, acting on the profile of the corneal tissue [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11]
a computer-controlled laser used in photorefractive keratectomy (PRK) A precise beam of pulsing ultraviolet light and flattens the cornea As it gives off almost no heat, the surrounding tissue is rarely affected
­ The excimer laser produces an ultraviolet beam of light that is emitted in pulses Each pulse removes 1/4000 millimeter of tissue from the surface of the cornea
A high-energy, cold laser that is used to reshape or sculpt the cornea surface to change the refractive power of the cornea
a pulsed, gas laser which lases when two atoms form a temporary excited molecule
Class of ultraviolet lasers, which is almost universally used for photorefractive keratectomy (PRK)
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-mer) In PRK the term has for practical purposes become synonomous with the argon-fluoride (ArF) gas version The wave length of an ArF excimer laser is in the far ultraviolet range at 193 nm
The excimer laser produces an ultraviolet beam of light which is emitted in pulses Each pulse removes 1/4000 millimeter of tissue from the surface of the cornea It would take about 200 pulses from an excimer laser just to cut a human hair in half The excimer laser has been used in industry since 1971 and has been used in ophthalmic surgery since 1983
A family of pulsed lasers operating in the ultraviolet region of the spectrum from 193-351 nanometers Back to Glossary
A medical device to emit laser energy created by a mixture of argon-fluoride gases Used in photorefractive kerotectomy (PRK) and LASIK (laser-assisted intrastromal keratoplasty) to reshape corneal curvature by ablating, or burning off, tissue from the center of the cornea
A "cold" laser used in refractive surgery to remove corneal tissue
an extremely precise "cold" laser beam that uses radiant energy to reshape the cornea of the eye The excimer laser has made refractive surgery fast and virtually pain-free and is used in most of the refractive procedures performed today
