Ophthalmological device for treating eye tissue

An ophthalmological device for treating eye tissue with laser pulses, comprising:

• a scanner system for dynamically deflecting the laser pulses;
• a projection optical unit for focused projection of the laser pulses in a projection direction;
• a zoom system, which is arranged downstream of the scanner system and upstream of the projection optical unit, between the scanner system and the projection optical unit, and which is configured to adjust the focused projection of the laser pulses in the projection direction in different zoom settings, whereby the zoom system has an optical axis and a virtual entry pupil which moves along the optical axis with the different zoom settings;
• and
• a displacement device, which is configured to displace the scanner system along the optical axis of the zoom system depending on the zoom setting of the zoom system, the displacement device comprising a drive coupled to the scanner system and configured to displace the scanner system along the optical axis of the zoom system, and one or more circuits configured to control the drive to displace the scanner system along the optical axis of the zoom system using a current zoom setting of the zoom system, wherein the displacement device is configured to adapt a position of the scanner system, with respect to a current position of the virtual entry pupil of the zoom system, for continuously maintaining a value of distance of the scanner system from the virtual entry pupil of the zoom system.
