ABSTRACT:
An optical stereoscopic microscope system is adapted for eye surgery and includes a conformer lens which fits over the eyeball being operated upon. A wide-angle aspherical lens system includes two convex-concave lenses and magnifies the image from the conformer lens to produce an inverted image. A beam splitter splits the inverted image into separated left and right inverted images each of which are reinverted by a pair of prisms, each prism pair being a pair of an Abbe Modification of Porro Prisms.
