Devices and methods for storing, loading, and delivering an intraocular lens
First Claim
1. An insertion system for delivering an intraocular lens into the eye of a subject, comprising:
- a cartridge having;
a body disposed along a longitudinal axis having a distal end and a proximal end;
a tapered lumen disposed along the longitudinal axis having an aperture at a distal end of the body; and
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; and
a handpiece comprising an upwardly facing protruding platform on which the cartridge is placed, wherein the platform is configured to fit within the opening, and a pushrod with a tip having a saddle and extending at least partly over the platform;
the opening disposed to permit passage of at least a portion of the tip when cartridge is placed onto the handpiece from above the handpiece.

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.

6. A method of inserting an intraocular lens, comprising:
-
providing a cartridge having; a body disposed along a longitudinal axis having a distal end and a proximal end; a tapered lumen disposed along the longitudinal axis having an aperture at a 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; providing a handpiece comprising a pushrod with a tip having a saddle; disposing the cartridge above the handpiece; attaching the cartridge onto the handpiece from above the handpiece; and while attaching the cartridge, disposing the tip such that the opening permits passage of at least a portion of the tip. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
