Devices and methods for storing, loading, and delivering an intraocular lens
View Patent ↗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.
1. A cartridge for delivering an intraocular lens into the eye of a subject, comprising:
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 closed aperture at the distal end of the body;
the aperture and at least a portion of the tapered lumen each having a cross-section defined by two generally opposing and interfacing sides: a first side and a second side, wherein the interface of the two sides define a horizontal axis;
The first side having a first width along the horizontal axis and a cross-section that is generally arcuate;
the second side having a surface having a substantially flat portion that is generally parallel to the horizontal axis and that is wider than the first width.
2. The cartridge of claim 1 , further comprising wings longitudinally disposed to either side of the body.
3. The cartridge of claim 1 , wherein the body further comprises a bottom surface having an opening disposed along the longitudinal axis.
4. The cartridge of claim 3 , wherein the opening comprises an elongated slot that is open at the proximal end of the body.
5. The cartridge of claim 3 , wherein the opening is disposed to receive a tip of a pushrod of an inserter handpiece.
