Device for Processing Eye Tissue by Means of a Pulsed Laser Beam

An ophthalmological device for processing eye tissue by means of a pulsed laser beam, comprising:

• a projection optical unit configured for projection of the pulsed laser beam in a projection direction onto a focus in the eye tissue;
• a first scanner system configured to scan the eye tissue with the pulsed laser beam along a processing line;
• and
• a second scanner system disposed upstream of the first scanner system and configured for beam-deflecting scanning of the eye tissue with the pulsed laser beam in a scanning movement along a scanning line superimposed on the processing line;
• wherein the ophthalmological device further comprises:
• an optical system with an optical transmission axis, arranged upstream of the first scanner system and configured to generate a varying divergence of the laser beam, such that the focus is displaced in the projection direction;
• and
• a rotation element arranged downstream of the optical system and configured to rotate about the optical transmission axis a scanning plane defined by the optical transmission axis and the scanning movement of the scanner system.
