    摘要: A method determines the position and/or radius of the limbus and/or the position and/or radius of the pupil of a patient eye. In the method, an image of the patient eye is obtained and a plurality of different ring-shaped comparison objects having respective radii and respective centers are provided. The image is correlated with the plurality of comparison objects to yield a local best match between the image and the comparison objects when there is a coincidence of one of the ring-shaped comparison objects and a ring-shaped jump in brightness in the image having the same radius and the same center. The comparison objects having a local best match with the image are determined. Thereafter, the position of the center of the comparison object having a local best match with the image is selected as the position of the center of the limbus and/or the position of the center of the pupil.

    摘要: The invention relates to an eye surgery microscopy system (1) having an imaging optic (14, 11) for the generation of the image of an object plane (15) and having an electronic image sensor (22), which detects the image of the object plane (15) and is connected to a computer unit (5) for the computation of the position of the center of a circular structure (44) of a patient eye (16). The computer unit (5) is designed for the computation of the position of a patient eye (16) outside of the center (52) of the circular structure (44) and provided with at least one marking (46, 48). The computer unit (5) determines the position of the at least one marking (46, 48) with reference to the computed center (52) by means of image processing via correlation with a comparison information, and an angular position of the at least one marking (46, 48) with reference to the computed center (52) by means of image processing.
