  Purpose

The investigators would like to test the treatment of onychomycosis using a 0.65 millisecond pulsed 1064 nm laser fitted with a special onychomycosis handpiece. The investigators will compare the success rates of those receiving laser treatments with untreated patients. This study will provide a clinical basis for determining the relative effectiveness of an increasingly utilized treatment method.

Onychomycosis
 Device: Laser Treatment (Pulsed Nd:YAG 1064 nm Laser)

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Treatment of Onychomycosis Using a 0.65 Millisecond Pulsed Nd:YAG 1064 nm Laser

Further study details as provided by Stanford University:

Primary Outcome Measures:
  • Number of Adverse Events [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
    The investigators will measure the number of patients experiencing adverse events (eg. pain during or post-laser therapy, rash, etc...)

  • Proximal clearance of fungus on nail [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    The investigators will measure proximal clearance of toenail (mm) at 1, 3, 6 months and 1 year.


Estimated Enrollment: 50
Study Start Date: September 2011
Estimated Study Completion Date: November 2013
Estimated Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment
  1. st visit: Patient will come into clinic for initial laser treatment with Nd:YAG 1064 nm laser fitted with special handpiece.
  2. nd visit: 2 weeks after initial laser treatment, patient will be seen for second treatment with Nd:YAG 1064 nm laser fitted with special handpiece.
 Device: Laser Treatment (Pulsed Nd:YAG 1064 nm Laser)
0.65 Millisecond Pulsed Nd:YAG 1064 nm Laser
No Intervention: Placebo
  1. st visit: For the control group, no treatment will be given.
  2. nd visit: 2 weeks after initial visit, patient will be seen for second visit

Detailed Description:

Current antifungal treatments have low cure rates and numerous side effects. A new treatment method, pulsed laser, has been purported to have high rates of treatment in a much shorter time frame than other treatments. While the treatment method has become increasingly popular, studies of its efficacy are few. The investigators hope to learn the cure rate of a novel treatment that is being used by more and more patients. This knowledge will be essential to physicians as they consider employing this new technology in their treatment methods.
