Abstract
A lens injector cartridge having an asymmetric bore. The asymmetric bore initiates the folding of the lens on one side only, thereby reducing the amount of energy imparted to the lens and the potential for damage to the lens. The gentle folding of the lens also assists in positioning the travel of the haptics down the bore, thereby reducing the potential for damage to the haptics.

- and
