  • Patent number: 6267756
    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.

  • Patent number: 5177511
    Abstract: An apparatus for producing images of an object and, in particular, for observing the rear portions of the eye by an illumination device, the light of which is focused on the object to be imaged and which preferably is provided with at least one laser. A scanning device, which produces a scanning motion of the light from the illumination device on the object to be imaged. A detector device has at least one detector which receives the light reflected from the object to be imaged an assessement and synchronization unit produces the image from the time-sequential output signal from the detector device.It is possible to gain essential ground-laying information about the object to be imaged, e.g. the fundus of the eye, by special types of illumination and/or the analysis of the scattered back light according to the most varied criteria.
