  • Publication number: 20040127911
    Abstract: A device for inserting a flexible intraocular lens into an eye including a tubular member and a plunger. The tubular member includes a staging area, a lumen, and an open distal end. The staging area supports the lens in an unstressed state prior to engagement by the plunger. In the unstressed state, the optic of the lens is suspended in a pocket to avoid any substantial contact with interior portions of the tubular member. The plunger includes a slot in its distal tip for receiving and gripping the lens. With this construction, the lens can be inserted into the eye in one continuous motion. Further, the plunger holds the lens when the lens is moved out of the tubular member.

  • Patent number: 6685740
    Abstract: This invention is a device for inserting a flexible intraocular lens (12) into an eye comprising a tubular member (16) and a plunger (18). The tubular member includes a staging area (45), a lumen, and an open distal end (95). The staging area supports unstressed state prior to engagement by the plunger. In the unstressed state, the optic (48) of the lens is suspended in a pocket to avoid any substantial contact with interior portions of the tubular member. The plunger includes a slot (132) in its distal tip fo receiving and gripping the lens. With this construction, the lens can be inserted into the eye in one continuous motion. Further, the plunger holds the lens when the lens is moved out of the tubular member.

  • Patent number: 6336932
    Abstract: An intraocular lens insertion device having a tubular member for receiving the lens and a plunger for pushing the lens into the eye. The lens is held in a suspended position by its haptics so that the optic portion of the lens does not contact the interior of the tubular member. The plunger tip is provided with a slot for holding the lens after it is expelled from the tubular member into the eye in order to alleviate the risks associated with uncontrolled unfolding of the lens or uncontrolled expulsion of the lens from the inserter into the eye.
