Abstract
A system for protecting a sector of tissue from exposure to surgically directed radiation includes a processor and an input device, a camera, and an output screen in electronic communication with the processor. A software resident on the processor receives camera data containing an image of a region of tissue, which includes at least a portion of a predetermined area desired to receive therapeutic radiation. The software also routes the image for display superimposes thereon first indicia indicative of the predetermined area. Data are received on a location of a sector of the tissue desired to be protected from the radiation and for superimposing on the displayed image second indicia indicative of the sector. In a specific embodiment the tissue is an eye and the predetermined area is at least a portion of the cornea.
