An intraocular lens (IOL) transfer case for transferring an IOL to an injection cartridge includes a lens holder for holding the IOL. The lens holder includes a bore. Folding members within the lens holder are configured to fold the IOL into a partially folded position when the IOL is slid through the bore across the folding members. The IOL transfer case also includes an interface configured to removably connect to an injection cartridge. The interface is positioned to deliver the IOL in the partially folded position within the injection cartridge when the interface is connected to the injection cartridge. The interface is configured to disconnect from the injection cartridge while leaving the IOL in the partially folded position to allow injection of the IOL. The IOL transfer case also includes a plunger connected to the lens holder. The plunger is configured to push the IOL in the partially folded position through the bore to deliver the IOL into the injection cartridge. The plunger is configured to stop within the injection cartridge before the IOL is completely folded.
