Treatment of Mild, Moderate, and Severe Onychomycosis Using 870-and 930-nm Light Exposure Some Follow-up Observations at 270 Days

We have previously reported the results of a clinical trial in which the Noveon laser was used to treat onychomycosis. In the 180-day follow-up therein it was noted that positive clinical impact was demonstrable by a clearly measurable decrease in positive fungal culture and a concomitant decrease in positive microscopy with periodic acid-Schiff-stained nail scrapings. Review of 270-day mycological data, which are now available, confirmed that there was further decrease in both measures. Indeed, 38% of the treated population had negative culture and microscopy, qualifying as "mycological cures." These mycological cures occurred in cases categorized as mild, moderate, and even severe disease. (J Am Podiatr Med Assoc 102(2): 169-171, 2012)
