Clinical investigations of leg ulcer treatment by copper vapor laser therapy-a preliminary report of a novel approach

Lower leg ulcer is sometimes a refractory disease. A recently developed copper vapor laser could be a promising light source for the treatment of these lesions. Preliminary results of clinical investigations of five patients with leg ulcer treated by copper vapor laser phototherapy are reported. Among them, three were cured, one obtained significant response, one had no response. Most patients were cured within 15 laser treatments. It was found that lower irradiation power and energy densities were required to obtain better results. Experiment details are given.
