 The study is a multi-center controlled study evaluating laser treatments of infected great toes in a randomized blinded study of approximately 125 subjects. Right and left great toes are randomized to treatment or no treatment. Samples from infected areas are sampled and evaluated for presence of fungus with KOH, PCR and culture tests. Nail bed clearing and nail plate growth are measured from high resolution photographs by a blinded evaluator. Subjects will be evaluated at baseline and at 8, 16, 24 and 48 weeks for safety and effectiveness of study treatment.
