Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a self sealing cannula and an aperture closure cannula relating to ophthalmic surgical equipment and more particularly to posterior segment ophthalmic surgical equipment. SOLUTION: This cannula is provided having a body, a sealing disc, and a cap. The sealing disc is located within the body and is compressed by the cap. An angled cut in the sealing disc allows microsurgical instruments to be inserted through the cannula into the eye. After removal, the cut in the sealing disc closes, preventing the loss of intraocular pressure. COPYRIGHT: (C)2009,JPO&INPIT
