ABSTRACT:
The outer cannula of an ophthalmic irrigator-aspirator has rigid tip and butt sections and a more flexible central section. The central section can be an elastomeric sleeve that extends between the tip and butt sections. The outer cannula includes reinforcement members that prevent the elastomeric sleeve from becoming completely closed by compression caused by a tight fit in an incision in a patient's cornea. The reinforcement members may be rigid or somewhat flexible.
