Abstract
Embodiments disclosed herein relate to an infusion cannula for infusion/venting of fluids to/from the eye to control intraocular pressure.

The tubular outlet is aligned with a first longitudinal axis and configured to extend through a septum of a valved cannula hub. The infusion cannula includes a retention piece extending from or coupled to the tubular body. The retention piece has an annular body surrounding the tubular body at the distal end of the tubular body and configured to be coupled to the valved cannula hub. An inner surface of the annular body has a profile configured to form a snap fit with an overhang formed along an outer surface of the valved cannula hub.
