GaAlAs 820nm diode laser system (Biotherapy 2001 Laser Unit, manufactured by OMEGA Laser Systems Ltd, London, U.K.) was used for the postoperative treatment of onychomycotic nails. Traditional treatment of onychomycosis has consisted of mechanical debridement of the affected nails accompanied by topical antifungal medication, systemic antifungal medications, or surgical removal and matrixectomy. The aim of this study was to evaluate the method of surgical avulsion using a CO2 laser (7W, 0.1mm) and a new protocol of low level laser therapy infrared diode laser GaAlAs (820nm, 100mW, 4J cm2) was applied for two weeks at three day intervals to improve the recurrence rate, pain score and healing time. Sixty patients were assigned to three groups (A, B and C). ANOVA statistical tests showed that there was a significant difference between the group A, B and B,C (P<0.005) in the measured mean healing time and pain score, but no statistical difference between group A and C (P<0.01). It was concluded that low level laser therapy reduced pain, improved the healing time and resulted in a lower recurrence rate.
