Claim:
1. An ophthalmological device for processing eye tissue by means of a pulsed laser beam (L), comprising: a projection optical unit configured for focused projection of the pulsed laser beam (L), produced by a laser source, into the eye tissue, a scanner system disposed upstream of the projection optical unit and configured for beam-deflecting scanning of the eye tissue with the pulsed laser beam (L) in a scanning movement (s′) performed over a scanning angle (β) along a scanning line (s), wherein the scanning angle (β) is an angle defined, at least in part, by an optical axis (o) of the projection optical unit and a focus of the pulsed laser beam (L), and wherein the scanning line (s) is a line along which the focus of the pulsed laser beam (L) moves during the scanning movement (s′), the projection optical unit being configured to 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, wherein the ophthalmological device further comprises a drive coupled to the projection optical unit and configured to tilt the projection optical unit about the axis of rotation (q), and a control module coupled to the drive and configured to control the drive for tilting the projection optical unit about the axis of rotation (q) in such a way that the focus of the pulsed laser beam (L) projected into the eye tissue is displaced dependent on the scanning angle (β).
