Abstract:
A system for improved, accurate treatment of an eye's fundus comprising:at least one optical setup for irradiating an eye's fundus with light emitted by a primary light source; at least one device to take optical images of said fundus; at least one secondary light source to generate a reference digital image on an eye's retina at a predetermined basic position of a treatment beam imaging optical system; at least one computer based setup for controlling and for digital image processing to accurately determine a treatment zone; means for simultaneous generation of a native digital image of said fundus; a unique marking of said treatment zone on said digital fundus image, creating a digital reference image; an adjustment means, comprising a liquid crystal device where each pixel can be addressed individually including polarizer and an analyzer and at last one optical imaging system; and wherein within one device, through said digital image processing and said adjustment means, said at least one optical setup for irradiating said fundus is adjusted to provide optimal irradiation characteristics to perform an improved, accurate treatment.
