Laser surgery is a type of surgery that uses special light beams instead of instruments for surgical procedures. (The word "laser" stands for "Light Amplification by the Stimulated Emission of Radiation.")
Lasers were first developed in 1960. Since that time, many modifications have been made and a number of different types of lasers have been developed. These differ in emitted light wavelengths and power ranges, as well as in their ability to clot, cut or vaporize tissue.
