Abstract
Self-contained eye positioner having an annular vacuum ring composed of a channeled support ring and an overmolded flexible sealing ring having an attached rigid hollow tube secured to a syringe by use of an attachment fixture. The syringe, which also functions as a handle, provides a vacuum source, the vacuum of which is communicated to the annular vacuum ring to suctionally adhere the annular vacuum ring to the eyeball for maneuvering thereof. Accompanying closely associated auxiliary devices are provided for use with the eye positioner. No external vacuum source is required.
