Abstract
The present invention relates to an apparatus 10 for ophthalmological laser surgery, with an optical imaging system for imaging a treatment laser beam 14 onto a focal point, with a temperature-measuring device for measuring a temperature assigned to the imaging system, and with an electronic control arrangement (22) connected to the temperature-measuring device, which is configured to control the focal-point setting in a manner depending on the measured temperature. The present invention further relates also to an associated method.
Claims19
Apparatus for ophthalmological laser surgery, comprising:
- a laser-surgical apparatus configured to direct a treatment laser beam onto a focal point in an eye to be treated;
- a temperature-measuring device for measuring a temperature of an optical component of the laser-surgical apparatus;
- and
- an electronic control arrangement in communication with the temperature-measuring device and the laser-surgical apparatus, the electronic control arrangement configured to control the focal point of the treatment laser beam based on the measured temperature of the optical component of the laser-surgical apparatus.
Apparatus according to any one of the preceding claims, wherein the temperature-measuring device comprises one or more temperature sensors arranged on the optical component of the laser-surgical apparatus.
Method for controlling a focal point of a treatment laser beam for ophthalmological laser surgery, comprising:
- directing a treatment laser beam from a laser-surgical apparatus onto a focal point within an eye to be treated;
- measuring a temperature of an optical component of the laser-surgical apparatus;
- and
- controlling the focal point of the treatment laser beam based on the measured temperature of the optical component of the laser-surgical apparatus.
