Abstract

A preloaded intraocular lens injection device (10) includes a retainer (40) for releasably holding an IOL (30) in an unstressed state. The retainer and IOL
are removably attached to an injector body (12) 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 (18a) is inserted through a small incision in an eye and a plunger (20) is advanced to push the IOL through and out the injector body tip and into an eye.
