ABSTRACT:
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.
