In the present ran-domized, blinded, controlled study, we assessed the ef-fects of a 308-nm excimer laser … A helium–neon (HeNe) laser uses an electrical discharge in the helium-neon gas mixture, a Nd:YAG laser uses either light focused from a xenon flash lamp or diode lasers, and excimer lasers use a chemical reaction. (Although less commonly used, the proper term for such is an exciplex laser.) The conversion efficiency of the light … Regulatory agencies have approved a number of excimer laser designs for use in eye surgery. Required fields are marked *, To explore our full product range, visit our secure e-commerce site. EXCIMER LASER(EXCIPLEX LASER) : Excimer lasers produce intense pulsed output in the ultraviolet. Since excimer lasers have very short wavelengths, the photons have high energy. After initial testing in 1950, the concept of radial-keratotomy eye surgery was then transferred and studied closely in Russia. This laser has the ability to remove considerably fine layers of surface material without altering the surrounding material. Excimer lasers are used in a wide range of medical applications today, including treatment of psoriasis, LASIK eye surgery and many refractive ophthalmology treatments.
