Abstract: An apparatus for the observation and treatment of the eye with a laser, having an illumination light source, whose light is focussed on the part of the eye to be observed and which preferably contains a laser, a scanning device, which generates a scanning movement of the light of the illumination light source on the background of the eye, a detector device, which receives the reflected light, an evaluation and synchronization unit, which generates from the time-sequential signal output of the detector device a visual representation of the portions of the eye to be treated and shows the visual representation, on a monitor, and a treatment laser device, whose light can be reflected on the part of the eye to be treated. The apparatus provides that a visual representation in which the location or locations to be treated are marked, can be superimposed on the visual representation of the eye at least on the monitor, and a control unit aligns the laser to the marked location.

Abstract: A device for the generation of a laser beam spot of adjustable size on an object, in particular in the human eye so as to enable laser surgery of the eye. The device includes a focusing device which projects the laser beam onto the eye with a small focusing spot and a large aperture cone and a deflector device which moves the focusing spot over the desired beam spot area in a predetermined scanning pattern. In this way, it is possible, for example, also to realize large treatment areas of any desired shape on the fundus without any injury to the frontal eye sections.
