The Nd:Yag lasers can treat toenail fungus by penetrating the nail and destroying the fungus embedded in and under the nail plate. It can do this without irritation of the skin as some topical anti-fungal agents do and without the potential systemic side effects (especially related to the liver) from oral prescription anti-fungal agents. It does take time to see results as the healthy nail takes 9 – 12 months to completely grow out.

Patients must aggressively prevent re-infection between and after the treatment course as well as into the future to achieve and maintain remission from this infection.
