摘要：
For processing eye tissue using a pulsed laser beam (L), an ophthalmological device includes a projection optical unit for the focused projection of the laser beam (L) into the eye tissue, and a scanner system upstream of the projection optical unit for the 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 projection optical unit is tilted about an axis of rotation (q) running perpendicularly to a plane defined by the scanning line(s) and the optical axis (o) of the projection optical unit, the tilting of the projection optical unit tilting the scanning line (s) in said plane. Tilting of the scanning line(s) enables a displacement—dependent on the scanning angle—of the focus of the laser pulses projected into the eye tissue without vertical displacement of the projection optical unit.
