A surgical microscopy system comprises microscopy optics for generating an image of an eye under surgery. A pattern generator generates a pattern to be superimposed with the image. An eye-tracker is provided for tracking a position of the superimposed pattern with respect to the image in case of a movement of the eye. The superimposed pattern comprises pattern elements that are equally distributed on first and second circles of different sizes, in order to give assistance when placing a suture during a corneal transplant. The superimposed pattern may also provide an assistance for orientating a toric intra-ocular lens.

Surgical microscopy system and method for performing eye surgery

A microscopy system for eye surgery with an objective lens is suggested, which provides a retroillumination system to generate a so-called red reflex illumination during an eye-surgical treatment, in particular during a cataract operation.
