OPHTHALMOLOGIC DEVICE FOR BREAKING DOWN EYE TISSUE
First Claim
1. An ophthalmological apparatus, comprising:
- a light source configured to generate light pulses;
a scanner configured to deflect the light pulses in a scanning direction;
an articulated arm;
a light projector connected to the articulated arm and configured for focused projection of the light pulses;
an optical transmission system arranged in the articulated arm and configured to transmit deflected light pulses to the light projector;
a transmitter configured to emit a reference light beam for determining a desired alignment of the scanning direction; and
a light sensor module configured to receive the reference light beam from the transmitter;
wherein the transmitter is arranged to transmit the reference light beam to the light sensor module via the optical transmission system in the articulated arm.

Abstract
An ophthalmological apparatus includes a base station having a light source generating light pulses, and an application head mountable on an eye having a light projector for focussed projection of the light pulses for punctiform breakdown of eye tissue. The application head has movement drivers moving the light projector in a feed direction and a first scanning direction. A scanner in the base station deflects the light pulses in a second scanning direction. The ophthalmological apparatus includes an optical transmission system transmitting deflected light pulses from the base station to the application head, and superimposing the light pulses deflected in the second scanning direction onto the movement of the light projector in the first scanning direction. Light sources with high light pulse rates, for example femtosecond lasers may be used, without impractical enlargement of the size of the application head.
