SYSTEM AND METHOD FOR PRODUCING ASSISTANCE INFORMATION FOR LASER-ASSISTED CATARACT OPERATION

摘要

A system for producing assistance information for a laser-assisted cataract operation on an eye (8) is described, wherein the system comprises: a laser cataract device (2) which has a laser beam source (3) which outputs a laser beam (4) and a laser beam scanning device (5) for producing cuts (28) in the cornea and/or in the capuscular sac of the eye (8) by scanning the laser beam (4) in the cornea and/or capuscular sac of the eye (8), a control device (12) for predefining a cutting geometry of the cuts by actuating the laser beam scanning device (5) according to actuation data, an imaging device (10) for imaging reference structures of the eye (8), an output interface (13), wherein the control device (12) is designed to determine the position of the reference structures and to produce a position data set which contains the cutting geometry and the relative position thereof in relation to the reference structures, and to output said position data record at the interface (13), an operation microscope (14) which has a microscope (15) for the enlarged imaging of the eye (8) on an image sensor which supplies image data, a display device (22) for displaying an image of the eye (8) according to the image data, an input interface (23) for receiving the position data set, and a control unit (21) which receives the position data set at the input interface (23), determines the position of the reference structures of the eye (8) with respect to the image data and inputs the cutting geometry, contained in the position data set, into the image displayed on the display device (22), appropriately in terms of position and size with respect to the reference structures.
