摘要： A device for injecting an intraocular lens (IOL) into an eye, the device having an injector body including a lumen and an open tip wherethrough the IOL is expressed from the device. An IOL loading bay is located in the passageway wherein the IOL is positioned and compressed. In a first aspect of the invention, the passageway diameter increases from a point adjacent the loading bay to the open tip to reduce compressive force on the IOL as it travels through the lumen. In another aspect of the invention, the plunger tip has a shape and diameter which has a close, sliding fit with the shape and diameter of the passageway to reduce the chance of the IOL becoming wedged between the plunger tip and the passageway wall as the plunger tip engages and advances the IOL through the passageway.

摘要： A preloaded intraocular lens injection device includes a retainer for releasably holding an IOL in an unstressed state. The retainer and IOL are removably attached to an injector body and are sealed in the same package for delivery to a surgeon. In an alternate embodiment, the retainer and IOL are coupled together and sealed in one package and the injector body is sealed in a separate package with the surgeon attaching the retainer to the injector body at the time of surgery. To deliver the IOL through the injector body, the retainer is removed from the injector body causing the IOL to release from the retainer and become located in an unstressed state in the injector body. A compressor is moved to the closed position to compress the IOL, the injector tip is inserted through a small incision in an eye and a plunger is advanced to push the IOL through and out the injector body tip and into an eye.
