Laser surgery is surgery using a laser to cut tissue instead of a scalpel. In laser surgery, a highly focused laser beam can efficiently ablate (either vaporize or chip away) the living tissue. At the same time, it seals (welds) capillaries, small blood vessels and nerve endings with significant benefits to patients. The laser seals small blood vessels as it cuts, resulting in a drastic reduction in bleeding and enables a number of new surgical procedures that are not practical with a conventional scalpel. The patient experiences a far more comfortable post-operation recovery. There is also a reduced risk of infection because the laser kills bacteria in its path producing a sterilizing effect.
