DEVICE FOR TREATING EYE TISSUE USING LASER PULSES

摘要

An ophthalmic device (1) for treating eye tissue (6) using laser pulses comprises a projection optical unit (12) for focussed projection of the laser pulses and a scanning device (2), with a movable mirror (20), arranged downstream from the projection optical unit (12), for deflecting the laser pulses projected by the projection optical unit (12) in at least one deflection direction. The ophthalmic device (1) moreover comprises a drive system (200) configured to displace the mirror (20) in parallel. The parallel displacement of the mirror (20) renders it possible to displace the focus of deflected laser pulses in the projection direction and therefore correct image field curvatures caused by the scanning device (2) arranged downstream from the projection optical unit (12) and, for example, image the deflected laser pulses in focus onto a plane.
