A system for easily transferring an intraocular lens (IOL) from a lens case (670) to an inserter (800), and then into a patients eye. The lens case has a transfer mechanism (672) therein which retains the IOL until engagement with the inserter. The transfer mechanism may include jaws (700, 704) having a closed configuration for retaining the IOL and an open configuration for releasing the IOL. Engagement of the inserter with the lens case automatically opens the jaws and transfers the IOL to the inserter. The IOL is transferred into a load chamber (844) of a nosepiece (606) rotatably coupled to a handpiece (600). After transfer of the IOL, the nosepiece is rotated from a load position to a delivery position. The IOL may have an optic (710) and a haptic (712a, 712b) coupled to the optic, and the lens case may be capable of configuring the haptic as desired to facilitate its transfer into an inserter and/or into the eye. For instance, the lens case may fold one or both of the haptics over the optic. Preferably, the lens case maintains the haptic in this position during transfer of the intraocular lens into an inserter and/or inserter cartridge. A manifold (662) for easily distributing a viscoelastic medium to the load chamber (844) of the inserter is also provided.Système permettant de transférer rapidement une lentille intra-oculaire (LIO) dun boîtier à un appareil dinsertion, puis dans loeil du patient. Le boîtier de lentille est doté dun mécanisme de transfert qui retient la LIO tant quelle nest pas en contact avec lappareil dinsertion. Le mécanisme de transfert peut inclure des mâchoires passant dun mode fermé pour la rétention de la LIO à une position ouverte pour sa libération. La mise en contact de lappareil dinsertion et du boîtier de lentille fait souvrir automatiquement les mâchoires pour le transfert de la LIO dans lappareil dinsertion. La LIO est transférée dans la chambre de charge dune partie de nez couplée rotatif à une partie manuelle. Après transfert
