Laser surgery is surgery using a laser (instead of a scalpel) to cut tissue. Examples include the use of a laser scalpel in otherwise conventional surgery, and soft tissue laser surgery, in which the laser beam vaporizes soft tissue with high water content. Laser resurfacing is a technique in which molecular bonds of a material are dissolved by a laser, a technique invented by aesthetic plastic surgeon Thomas L Roberts, III using CO2 lasers in the 1990s.
Laser surgery is commonly used on the eye. Techniques used include LASIK, which is used to correct near and far-sightedness in vision, and photorefractive keratectomy, a procedure which permanently reshapes the cornea using an excimer laser to remove a small amount of tissue.
Types of surgical lasers include carbon dioxide, argon,Nd:YAG, and KTP.
