Combination of a triple wavelength (650 nm, 810 nm, and 915 nm) class IV laser system and local mechanical abrasion in the treatment of chronic toenail onychomycosis: an uncontrolled prospective pilot study.

Background: Toenail onychomycosis is a frequent fungal infection that is difficult to treat, especially in elderly patients. Diverse local and systemic antifungal treatments are available with variable results. Recently, different laser systems have been proposed for the treatment of onychomycosis, among them a class IV laser system adopting three different wavelengths, that is, 650, 810, and 915 nm (K-Laser Cube 3TM).
