A toenail fungus laser works by shining a focused beam of light in a narrow range, more commonly known as a laser, into a toenail infected with fungus (onychomycosis). The laser penetrates the toenail and vaporizes fungus embedded in the nail bed and nail plate where toenail fungus exists. The toenail fungus targeted laser is tuned to a specific frequency that effects cells that are responsible for infection.

There are various manufacturers with lasers currently available or soon to be available. Each manufacturer may have a specific wavelength, wavelengths, pulse frequency or duration schedule that they use. When you consult with your physician they can go over the details of the device they use treat the toenails infected with fungus.
