An ophthalmological device () 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&#x2014;dependent on the scanning angle&#x2014;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&#x2014;dependent on the scanning angle&#x2014;the focus of the laser pulses projected into the eye tissue without vertical displacement of the projection optical unit.
