Chart Review of the Efficacy of the GenesisPlus 1064 nm Nd:YAG Laser in the Treatment of Onychomycosis

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine if toenail onychomycosis can be reduced by means of exposure to laser energy from the Cutera® GenesisPlus 1064 Nd:YAG laser system.

Detailed Description
-----------------
This is a retrospective, open-label, single-centre study for the collection of clinical data on the efficacy and safety of the Cutera® GenesisPlus 1064 nm Nd:YAG laser for the treatment of nail fungus (onychomycosis). Safety and efficacy of treatment with the GenesisPlus laser will be evaluated by (1) assessment of subject's great toenail photographs at baseline and after two treatments with GenesisPlus Laser utilizing planimetry measurement of infected vs. clear nail area in target toenail photographs, (2) by clinical and subjective review of acute and follow up adverse events that may have resulted from laser treatment of the target toenails.
