Eye surgery microscope having an entity for measuring an ametropia
First Claim
1. A microscope for usage in eye surgery, wherein the microscope provides an imaging beam path for imaging a portion of an eye of a patient and a measurement beam path for measuring an ametropia of the eye of the patient, and wherein the microscope comprises:
- an objective lens traversed by the imaging beam path and having an object plane in which the eye of the patient is disposable;
at least one of at least one ocular disposed in the imaging beam path behind the objective lens for generating an image of the object plane and a camera disposed in the imaging beam path behind the objective lens for detecting an image of the object plane,a measurement light source for generating a measurement light beam;
a measurement module disposed in the measurement beam path and having at least one light detector detecting measurement light;
optics traversed by the measurement beam path for directing the measurement light beam onto a retina of the eye of the patient and for providing measurement light reflected at the retina to the measurement module; and
a controller;
wherein the measurement module and the controller are configured to determine a position of an image of the retina along the measurement beam path, wherein the image of the retina is generated by the optics, and to output a measurement value representing the ametropia of the eye of the patient.

Abstract
An eye surgery microscope 1 having an illumination beam path 9 for imaging a portion of an eye 3 of a patient and a measurement beam path 25 for measuring an ametropia of the eye. The microscope comprises an objective lens 11 having an objective plane 13 in which the eye of the patient is disposable; at least one ocular 17 or a camera 19 for generating and detecting an image of the object plane, respectively; a measurement light source for generating a measurement light beam 29; a measurement module 41 having a light detector; optics traversed by the measurement beam path for directing the measurement light beam onto the retina 7 of the eye of the patient and for providing measurement light 39 reflected at the retina to the measurement module; and a controller; wherein the measurement module and the controller are configured to determine a position of an image of the retina generated by the optics along the measurement beam path and to output a measurement value representing the ametropia of the eye of the patient.
