Zusammenfassung:	A lighting device is accommodated in a stereo-microscope or binocular in order to create a bright red reflex on the retina with sharp contrasts for the performance of a cataract operation. The cluster of light rays (12) is divided into several smaller clusters (13) by a mirror and prism arrangement (10, 11). The lighting is directed on to the eye from the viewing point of the surgeon (HB). The operation can be watched by a second observer (MB).
