Zusammenfassung:	A cannula (10) is provided having a body (12), a sealing disc (14), and a cap (16). The sealing disc (14) is located within the body and is compressed by the cap. An angled cut (40) in the sealing disc allows microsurgical instruments to be inserted through the cannula into the eye. Upon removal, the cut (40) in the sealing disc closes, preventing the loss of intraocular pressure during ophthalmic surgery.
