Contactless visualization system for a surgical microscope for eye surgery

A surgical microscope for eye surgery, the surgical microscope comprising:

• a contactless visualization system having an ophthalmic loupe;
• said ophthalmic loupe being configured to be positionable in front of a patient's eye and to supply a real and vertically and laterally inverted image of an eye fundus of said patient's eye in an intermediate image plane that is observable by said surgical microscope;
• said ophthalmic loupe including a first lens element and a second lens element, wherein, in a state positioned in front of said patient's eye, said first lens element is closer to said patient's eye than said second lens element;
• a wall extending from said first lens element to said second lens element, said wall having a free end in a form of a mount in which said second lens element is held;
• said wall having at least one passage opening formed in said wall at an elevation to facilitate removal of liquid possibly present in an intermediate space between said first lens element and said second lens element;
• and,
• said first lens element having a boundary surface facing said second lens element and said boundary surface having a curved form, with said at least one passage opening including a lower edge;
• and,
• said wall abutting said first lens element so as to cause said lower edge and said boundary surface of said first lens element to conjointly define a common surface to preclude formation of a depression or annular channel therebetween.
