ABSTRACT:
A stereoscopic microscope system is adapted for vitrectomy eye surgery. A conformer lens positions the eye being operated upon and an aspherical lens system, adjacent the conformer lens, produces an inverted image. That image is reinverted by a prism system having two pairs of prisms, each pair being an Abbe's Modification of Porro prism system. Each prism of the prism system has the same size and shape and the prisms are cemented together to form a unitary prism cluster.
