Abstract:
An ophthalmic device for treating eye tissue using laser pulses comprises a projection optical unit for focused projection of the laser pulses and a scanning device, with a movable mirror, arranged downstream from the projection optical unit, for deflecting the laser pulses projected by the projection optical unit in at least one deflection direction. The ophthalmic device moreover comprises an optical correction element arranged downstream of the scanning device, which correction element is configured to image, in a focused manner, the laser pulses deflected by the scanning device on an intended treatment area in the eye tissue. The optical correction element renders it possible to therefore correct image field curvatures caused by the scanning device arranged downstream from the projection optical unit and, for example, image the deflected laser pulses in focus onto a plane.
