Abstract
A cannula for intraocular surgery including a cup, a tube including a wall and having a tube outer diameter, the tube extending from the cup to a distal end and defining a longitudinal axis. In one implementation, the distal end includes a first portion and a second portion, the first portion having a tip and being narrower than the second portion. A gripping section is formed in the wall. The gripping section has a diameter that is less than the tube outer diameter. The gripping section allows the sclera to deform into the reduced diameter in order to increase a retention force of the cannula in the eye while minimizing damage to the tissue of the eye.
