Lasers: Aspects of effectiveness and safety

Abstract

The use of laser therapy by physiotherapists has shown a marked increase in popularity over recent years. Effectiveness and safety of lasers is essential. The results of an investigation by the CSIR of some infrared lasers is reported, highlighting, e.g., that all that SAYS laser may not BE laser. New legislation that will ensure that lasers conform with the minimum requirements to be safe and effective products, is discussed. The risk of laser radiation and product/premises licenses as a means of ensuring safe use of lasers, are explained.
