Abstract
A cartridge for delivering an intraocular lens into the eye of a subject that comprises a body disposed along a longitudinal axis having a distal end and a proximal end, and a tapered lumen disposed along the longitudinal axis having an aperture at the distal end of the body. The aperture and at least a portion of the tapered lumen each consist of an upper portion and a lower portion. The upper portions of the aperture and lumen each have a first width and a cross-section that is generally arcuate. The lower portions of the aperture and lumen each have a cross-section that is generally horizontally disposed and have a second width that is greater than the first width of the aperture and lumen. The cartridge may be loaded with an intraocular lens using a packaging system. The intraocular lens may be placed into the eye of a subject using a corresponding inserter having a pushrod with a saddle disposed at the tip thereof. The intraocular lens is preferably draped over the saddle during insertion.
