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.

Upon removal, the cut (40) in the sealing disc closes, preventing the loss of intraocular pressure during ophthalmic surgery.
