Laser surgery benefits for patients Less Bleeding: As it cuts, the laser seals small blood vessels. This drastic reduction in bleeding enables a number of new surgical procedures that are not practical with conventional scalpel. Less Pain: The CO2 laser beam seals nerve endings and lymphatics, resulting in less edema and pain. The patient experiences a far more comfortable post-operative recovery. Reduced risk of infection: This is one of the unique features of the CO2 laser beam. It efficiently kills bacteria in its path, producing a sterilizing effect. Quicker recovery time: Reduced risk of infection, less bleeding, less pain and less swelling often allow the patient a far quicker recovery after the surgery.
