Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 50 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: Even though this study has recruited more than 10 participants, it is a feasibility study, designed to test the prototype rather than measuring health outcomes. It is to confirm the operating specifications before beginning a full clinical trial.
Masking: None (Open Label)
Primary Purpose: Device Feasibility
Official Title: Study of the V-Raser Diode Laser System in the Treatment of Onychomycosis
Study Start Date : October 2011
Actual Primary Completion Date : August 2013
Actual Study Completion Date : August 2013

Arm Intervention/treatment
Experimental: Diode Laser Treatment Device: Diode Laser Treatment
Laser treatment once every 6 weeks, for a total of 4 treatment sessions
Other Name: V-Raser

Primary Outcome Measures :
  1. Amount of Clear Nail Growth from Baseline in mm or as measurement of total area of involvement [ Time Frame: 12 months ]
    Amount of lesion-free toenail growth (mm or total area of involvement) from Baseline, as judged by computer software analysis of photos.
