The topic of new laser treatments for fungal nails is often discussed among podiatrists. Toenail fungus is a condition that can affect people of any age and if left untreated, can spread to more nails, more of the foot, and even the rest of the body. Laser fungal nail treatment involves the vaporization of the fungus in the toenail via laser, leaving the skin around the affected nail unharmed. A cool laser is the newest technology in laser treatment and requires no anesthesia, allowing patients to return to normal activities and grow out a regular appearing nail after one treatment. Depending on the severity of the fungus, repeated sessions may be required.
