Abstract
A thin walled, hubbed cannula with an exterior diameter of approximately that of a 20 gauge surgical instrument and in interior bore having a diameter that is slightly larger than a 23 gauge or 25 gauge surgical instrument. The scleral contact surface of the hub of the adapter also can be rounded to provide a pivot point for the surgical instrument shaft, thereby reducing bending forces on the relatively thin shaft of the instrument.
