Surgical microscopy system and method for performing eye surgery

摘要

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.

主权项

1. A method associated with introducing an intraocular lens into a lens capsule of an eye such that the intraocular lens will have a correct orientation relative to a centre of a pupil of the eye, the method comprising:
generating a microscopic image of at least one of a portion of an iris and a portion of a limbus of the eye, using a microscopy optics; generating a first partial pattern superimposed with the microscopic image, such that the first partial pattern can be recognized in the microscopic image as a straight line, and inserting the intraocular lens into the eye and orienting the intraocular lens relative to the first partial pattern superimposed with the microscopic image; wherein the first partial pattern is generated such that the first partial pattern superimposed with the microscopic image has an adjustable orientation relative to the microscopic image.
