What is Excimer Laser?
Excimer laser is a method used successfully for treatment of refractive defects for over 20 years. Excimer laser is a device which generates an ultraviolet light at 193 nm wavelength using Ar F gas. The laser beam generated by the device eliminates the target tissue with the desired thickness and width.
This results in a permanent change in the cornea layer which corrects myopic, hypermetropic and astigmatic defects. Lasik, Femtolasik Lasek and PRK are various applications of Excimer laser treatment.
