New suspension of operating microscope and chair.

We developed a new operating microscope system consisting of magnetically locked suspension for the microscope, an operating chair that makes synchronous coaxial rotation with the microscopy, and has a cryostat and electric coagulator built into its back, and a slit lamp with brighter illumination. The new operating microscope system, which permits a wider range of motion and a clearer view of the operative field than conventional microscopes, has proved useful in such surgical procedures as the running suture in corneal transplantation, loop fixation in intraocular lens implantation, preparation of an intrascleral pocket in detachment surgery, open sky vitrectomy, and decompression of the optic canal.
