A laser is designed to emit light energy, penetrating the target nail and related surrounding tissue. The laser is pain free and no warm or hot sensations are felt. The laser’s heat helps destroy fungal spores.

The duration of the treatment – which is usually about half an hour – depends on the severity of the fungal infection and the exact number of nails being treated in the session. During this time, the laser device passes over the infected nails multiple times. The severity of the infection will likely determine the required number of treatment sessions, which are usually spaced several weeks apart.

Patients are usually advised in their after-care instructions to keep their nails clean and dry. A topical antifungal and shoe spray, clean moisture wicking socks should be worn as part of the treatment regime.
