For processing eye tissue by means of a pulsed laser beam (L), an ophthalmological device comprises a projection optical unit for the focused projection of the laser beam (L) into the eye tissue, and a scanner system disposed upstream of the projection optical unit and serving 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 can be 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 bringing about a tilting of the scanning line (s) in said plane. The 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.
