For processing eye tissue (8) by means of femtosecond laser pulses, an ophthalmological device (1) includes a projection optical unit (2) for the focused projection of the femtosecond laser pulses into the eye tissue (8). Disposed upstream of the projection optical unit (2) is a first beam-deflecting scanner system (3) for scanning the eye tissue (8) with the femtosecond laser pulses along a processing line. A second beam-deflecting scanner system (5) is disposed upstream of the first scanner system (3) and is designed for scanning the eye tissue (8) with the femtosecond laser pulses in a scanning movement superimposed on the processing line and running in a deflection plane. The second scanner system (5) has a scanner speed that is a multiple of the scanning speed of the first scanner system (3). A rotation system is provided for aligning the deflection plane with a defined angle with respect to the processing line.
