Low Level Laser Therapy Essay

Laser therapy has been considered for many decades as exerting a positive effect on wound healing. The biostimulative effects of repeated low level laser therapy (LLLT) were introduced in the late 1960s(1).
Low-level laser therapy (LLLT) also called low-intensity laser therapy (LILT) or low-energy photon therapy (LEPT) has received clearance from the United States Food and Drug Administration. The clinical efficacy of LLLT in wound healing has been reported. It has been found to significantly decrease the time of wound healing (2).
Diabetic foot ulcers and chronic venous ulcers are cutaneous lesions that are difficult to treat and heal. Venous ulcers are commonly known as chronic wounds with a prevalence of 1% of adults in developed countries. Diabetic foot ulcer is a serious complication of diabetes mellitus and is the single most important risk factor for lower limb

Laser related energy is only absorbed by a thin layer of adjacent tissue and for this reason some researchers use low-intensity laser that has a low power of penetration, with wavelengths between 640 and 940 nm in a punctiform application to the lesion (13). Several studies have assessed the effects of low-intensity laser on superficial wounds healing. Some have used clinical wounds such as ulcers of different sizes and depths (14) and others have developed models of superficial wounds in animals (15). These diverse methods have produced a variety of results and conclusions on the effects of LLLT.
We try to review the major articles about application of Low-level laser therapy for venous leg ulcer duration in order to help clinicians and patients to have a better understanding of these technologies and can choose the better therapeutic process. A highly standardized evidence-based review can be one of the best references for concern ones to decide about their treatment
