摘要：
An ophthalmological device (1) for processing eye tissue includes a projection optical unit for focused projection of a laser beam (L) into the eye tissue, and a scanner system upstream of the projection optical unit for beam-deflecting scanning of the eye tissue with the laser beam (L) in a scanning movement (s) performed over a scanning angle along a scanning line(s). The ophthalmological device includes at least one optical element upstream of the projection optical unit, the optical element configured to generate a divergence—dependent on the scanning angle—of the laser beam (L), the scanning line(s) tilted in a plane running through the optical axis of the projection optical unit and the scanning line(s). Tilting of the scanning line(s)displaces—dependent on the scanning angle—the focus of the laser pulses projected into the eye tissue without vertical displacement of the projection optical unit.
