Abstract
A microscope for performing an opthalmo-surgical intervention, in particular for a contactless wide-angle observation of an eye during an intervention, is provided. The microscope has a tube (1a) having an objective and an ocular, a holding arm (1), at which the tube (1a) is attached such that a movement of the objective with respect to the holding arm (1) along the optical axis of the objective is possible, an optical accessory part (8a) between the objective and the eye and a holding device for the optical accessory part (8a). The holding device for the optical accessory part is attached at the holding arm (1) by means of an attachment device (2) in such a way that the holding device does not take part in movements of the objective along the optical axis of the objective. Thereby, when changing the picture angle, a re-adjustment is highly simplified.
