Abstract: A device intended to permit photocoagulation or phototherapy at low cost and in a shorter time. For this purpose, an ophthalmology appliance includes a radiation source having several discrete individual emitters. The therapy beam path leading from the radiation source to the treatment area projects an image of at least respective portions of different individual emitters simultaneously onto surfaces spaced apart from each other in the treatment area. This permits simultaneous generation of several coagulation foci and dispenses with the need for electromechanical beam-deflecting units, which permits a shorter treatment time.

Abstract: A polarization beam splitter selectively decouples detection light onto a detector such that it has a polarization direction that differs from the emitted illumination light. This enables the detection of the light scattered back in the eye lens at a high level of accuracy, since stray light from reflections at optical components of the light path is suppressed. In the generating of photo disruptions or other incisions, the ray exposure of the retina may be reduced in that the incisions being furthest away from the laser are induced first such that laminar gas inclusions with an existence duration time of at least 5 seconds result. In this manner the laser radiation propagated in the direction of the retina in further incisions are scattered and partially reflected such that the influence impinging upon the retina is reduced.
