Abstract
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 ophthalmological device includes a divergence modulator disposed upstream of the scanner system for dynamically varying the divergence of the laser beam (L), whereby the scanning line (s) is tilted in a plane running through the optical axis of the projection optical unit and the scanning line(s). 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.
