Treatment of Onychomycosis Using a 0.65 Millisecond Pulsed Nd:YAG 1064 nm Laser

This study has been completed.

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.

Condition Intervention
Device: Laser Treatment (Pulsed Nd:YAG 1064 nm Laser)

Study Type: Interventional
Study Design: Allocation: Randomized
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:
  • The Primary End Point Was the Percentage of Patients With a Negative Mycological Culture. [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • Proximal Clearance of Fungus on Nail [ Time Frame: 1 year ]
    The secondary end point was proximal nail plate clearance as assessed directly by a single study physician, who measured the clinical involvement defined as total length of abnormal nail per each nail of each of the patients' toenails, and confirmed by digital analysis of toenail photographs with ImageJ software.

Enrollment: 27
Study Start Date: September 2011
Study Completion Date: November 2013
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.
