Abstract
A contactless visualization system is for a surgical microscope for eye surgery. The system includes an ophthalmic loupe positionable in front of a patient's eye and for supplying a real and vertically and laterally inverted image of an eye fundus of the patient's eye in an intermediate image plane observable by the surgical microscope. The ophthalmic loupe includes a first and a second lens element. In a state positioned in front of the patient's eye, the first lens element is closer to the patient's eye than the second lens element. A wall extends from the first to the second lens element. The wall has a free end in a form of a mount in which the second lens element is held. The mount includes at least one cutout in which an edge of said second lens element is exposed in order to give a surgeon operating space.
