The invention contemplates laser-aseptic phototherapy, for enhanced sterilization of an area of prospective surgical invasion of living tissue, by first administering, intravenously, orally or otherwise as appropriate, a photosensitizing agent having the property, in the course of an acceptable period of time, of selective concentrated absorption in bacteria and other microorganisms such as those which exist at depth in hair follicles, and then, following lapse of the time period, applying laser irradiation to the area of prospective surgery, using a wavelength and power density selected for absorptive response by the photosensitive agent, whereby microorganisms are destroyed at and beneath the irradiated area.

The method of preparing an area of living tissue for surgical invasion, by destroying infective target micro-organisms within said area, said method comprising irradiating said area with first and second separate laser beams of intensity and wavelength selected for interaction with said target micro

The method of preparing an area of living tissue for surgical invasion, by destroying infective target micro-organisms within said area, said method comprising irradiating said area with first and second separate laser beams of intensity and wavelength selected for interaction with said target micro-organisms, each of said beams having properties of spatial and temporal coherence, and said beams having different physical properties at tissue impingement within said area, wherein the difference is in respect of at least one physical property the combined power of said beams being at least 10 milliwatts and the intensity of said beams being less than sufficient to induce photocoagulation, photovaporization, photonoptical breakdown or photoablative decomposition of living tissue and/or cells, whereby within said area to effect intra-micro-organism changes leading to destruction in the micro-organism.
