Abstract
A shuttle, vial and injector are provided for storing and presenting an IOL to a patient. The shuttle includes operably engaged shuttle plates having a set of confronting surfaces that flex about a flexure interface between a storage configuration, with at least an optic of an IOL in a nominal state and a loading configuration, with at least an optic of an IOL in a deformed state. The vial engages the shuttle and maintains the shuttle in the storage configuration. The injector receives the shuttle from the vial and includes surfaces for flexing the portions of the shuttle plates to the loading configuration upon engagement with the injector, wherein the shuttle plates impart a predetermined curvature to at least a portion of the IOL.
