摘要：
A surgical microscope for imaging structures of an eye includes: a front optical unit, an illumination device which has an illumination-radiation-emitting illumination source and which illuminates the retina of the eye with an illumination spot via an illumination beam path which extends through the front optical unit, a camera and an adjustable camera optical unit disposed upstream thereof, an imaging beam path which extends through the front optical unit and the camera optical unit, and a control device which controls the camera optical unit and sets the latter in such a way that the retina of the eye in the region of the illumination spot is imaged on the camera. The control device varies a focusing state of the camera optical unit and, as a result thereof, records a plurality of images of the retina in the region of the illumination spot, the images being focused in different depth planes, and establishes a refractive value of the eye from these images.
