Abstract
For processing eye tissue () by means of femtosecond laser pulses, an ophthalmological device () includes a projection optical unit () for the focused projection of the femtosecond laser pulses into the eye tissue (). Disposed upstream of the projection optical unit () is a first beam-deflecting scanner system () for scanning the eye tissue () with the femtosecond laser pulses along a processing line (s). A second beam-deflecting scanner system () is disposed upstream of the first scanner system () and is designed for scanning the eye tissue () with the femtosecond laser pulses on a scanning curve (f) superimposed on the processing line (s). The second scanner system () has a scanner speed that is a multiple of the scanning speed of the first scanner system (), and comprises at least one deflection mirror, a first scanning axis () and a second scanning axis (). A control module () controls the deflection of the femtosecond laser pulses about the first scanning axis () and the deflection of the femtosecond laser pulses about the second scanning axis () in accordance with a defined curve shape, a defined curve amplitude and a defined curve orientation of the scanning curve (f).
