Abstract: Low energy laser therapy (LELT) was used to treat chronic leg ulcers. Seven patients, aged 59 to 96 years, with 11 leg ulcers were referred for laser therapy by plastic surgeons. They had a history of ulceration of 3 - 50 years and five of the patients had breakdown of previous skin grafts. Laser treatments were administered with a microprocessor-controlled device. A 22 red ($lambda $EQ 660 nm) laser head was utilized to provide a dose of (4 - 6) J/cm$+2$/ and 7 infrared ($lambda $EQ 880 nm) head to provide a dose of (4 - 8) J/cm$+2$/. The patients were treated three to five times per week, 25 - 30 treatments per course. Three patients underwent two courses of laser therapy with three weeks interval between them. All patients, after 5 - 10 laser treatments, have gotten relief of pain and decreased the amount of analgesics used. All ulcers in six patients were completely healed and two ulcers in the seventh patient decreased in size by 75%. One may conclude the developed laser methodology might be used as a preventative measure to avoid plastic surgery or improve its success. !23
