This study tested a laser treatment using two different wavelengths (1,064 and 532 nanometers) to treat toenail fungal infections. Fifteen patients with toenail fungus received eight weekly laser sessions. The treatment was safe and worked best for mild cases, curing 100% of them, but was less effective for severe infections. Although patients experienced some pain during treatment, the overall results suggest laser therapy could be a useful option for treating mild fungal toenail infections without the side effects of oral medications.
