Laser surgery is surgery performed using a laser instead of a scalpel to cut tissue. Laser surgery uses an intense beam of light that is precisely focused to cut tissue. The energy contained in the laser beam vaporizes the water found in body tissues, allowing a precise "cut" that seals blood vessels and nerve endings, resulting in less bleeding and pain. Additional benefits of laser surgery are reduced swelling at the surgery site, reduced risk of infection, and a quicker recovery.
