An ocular fixation device for freehand pars plana vitrectomy.
An adaptation of the stereotaxic micromanipulator is described which provides ocular support and stabilization during freehand vitrectomy. It consists of a baseplate for immobilization of the patient's head and an ocular fixation arm assembly which connects to the eye by grasping a special Flieringa ring sewed to the postlimbal sclera. The ocular fixation arm can be made alternately flexible or rigid, thereby providing needed ocular mobility or stability during the operation as is desired by the surgeon.
