Disclosed are an intraocular lens (IOL) push rod, an IOL cartridge, multiple embodiments of an IOL cartridge housing, and a method for folding an IOL for insertion into an eye during ocular surgery. The distal end of the push rod is contoured to apply force to a substantial portion of the perimeter of an IOL to advance the IOL through a bore of the cartridge. Two hinges couple flanges on the IOL cartridge to a central portion that supports an IOL when protected by a cover for an extended storage time. The IOL cartridge has a locking element that engages a cartridge housing or IOL inserter. Each cartridge housing accepts the IOL cartridge with the IOL in an unfolded state. The cartridge bore is unobstructed and is tapered to fold one side of the IOL over the other as the IOL is advanced through the bore and into an eye.
