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.
