Abstract
Provisions must be made in surgery microscopes for eye surgeries through the selective adding of optics so that a non-reversed and erect-standing image can be produced including that of the fundus of the eye. A device for the image reversion is fastened on the microscope so that it can be moved into the beam path and is then provided between the lens and the eye so that the overall height of the microscope is not influenced. This inventive arrangement can be utilized very universally on very differently designed microscopes and can be operated with prism systems of varying design's.
Claims21
A microscope for the wide-angle viewing of an eye to be treated with an optical device which is provided between a lens and the eye and which creates a reversed image for facilitating a viewing of the fundus of the eye, and with a device for image reversion and image erection, said device being configured to lie in a beam path of the microscope, wherein the device for image reversion and image erection consists of a prism system which has a small height, and which is carried by a bolder fastened on the microscope so as to be moved or swung into the beam path of the microscope between the lens and the eye to be treated, wherein the prism system is provided directly in front of the lens at a distance from the eye.
