ABSTRACT:
Surgical procedures on biological tissue are carried out with the aid of a laser with substances being applied to the tissue before or during the treatment and these substances are absorbent in the range of the wavelength of the laser beam. A surgical manipulator can be provided and equipped with suction and irrigation channels and the substances can be directed to one of these channels via a metering unit. The application of substances such as sulfisomidine or sulfacetamide increases the ablation rate and reduces the threshold of the ablation process. At the same time, sensitive structures are protected from the damaging effects of the laser radiation as well as from the stray radiation and fluorescence radiation triggered by the laser radiation during the application of microsurgery to the eye.
