Laser Surgery

Laser surgery is a type of surgery that uses a laser (in contrast to using a scalpel) to cut tissue. 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 the human tissue. Lasers are used for surgical applications in either contact or non-contact mode. In the former case, laser radiation heats up a specially designed surgical tip, which, in turn, is used to cut tissue through thermal conduction. Diode lasers are well suited for this mode of operation. Alternatively, in the non-contact mode, wavelength  of the laser source is selected to utilize high water content of most soft tissues.  Erbium-doped fiber lasers, Thulium-doped fiber lasers and Mid-IR hybrid lasers have demonstrated their suitability for this mode of operation.
