Abstract

An eye surgery surgical system includes a device for displaying a relative position of a section of a surgery object in a 3D reconstruction of a region of an eye, a device for continuously providing at least two data records relating to at least partly overlapping portions of the region of the eye and of the section of the surgery object to a computer, a computer program for continuously ascertaining the relative position of the section of the surgery object and continuously ascertaining the 3D reconstruction of the eye from the data records provided. The program includes a first routine for continuously ascertaining the relative position of the section of the surgery object and the 3D reconstruction of the region of the eye from the data records provided via a registration method and a second routine for adapting the registration method based on a criterion.
