Abstract
A surgical microscope is disclosed with an observation beam path for generating an optical image from the eye, an illumination device for illuminating the eye, wherein the illumination device is designed for illuminating the eye with illumination light that contrasts eye lens pieces, in order to generate an optical contrast image that contrasts the eye lens pieces as optical image from the eye by means of the observation beam path, at least one digital camera, to which the optical contrast image is fed and which creates a digital contrast image from the optical contrast image and outputs it, an image processing unit, which is connected to the digital camera for receiving the digital contrast image and which is designed to find locations of increased contrast in the digital contrast image and to generate and output a superimposition image representing the locations of increased contrast, and a superimposing device.
