ABSTRACT:
An ophthalmological apparatus (1) comprises a base station (11) having a light source (51) for generating light pulses, and an application head (3) which can be mounted on an eye (2) having a light projector (58) for the focussed projection of the light pulses for punctiform breakdown of eye tissue (22). The application head (3) additionally has movement drivers (57) for moving the light projector (58) in a feed direction and in a first scanning direction. A scanner (52) is arranged in the base station (11) in order to deflect the light pulses in a second scanning direction. In addition, the ophthalmological apparatus (1) comprises an optical transmission system for transmitting deflected light pulses from the base station (11) to the application head (3), and for superimposing the light pulses deflected in the second scanning direction onto the movement of the light projector (58) in the first scanning direction. It is possible to use light sources with high light pulse rates, for example femtosecond lasers, without the need for impractical enlargement of the overall size of the application head (3) owing to the scanner. In addition, it is possible while safeguarding a manageable overall size of the application head (3) to make use of light sources with high light pulse rates, something which increases the accuracy of treatment and reduces the burden on the eye (2).
