Abstract
Abstract Intraocular lens package for packing, shipping or storage of intraocular lenses including a base and a configured cavity for the containment of an IOL and a lens retainer cap fitting over and about the configured cavity to contain the IOL within a seat. The haptics rest on ramped surfaces adjacent to a centralized lens cavity which is supported by semi-tubular struts. A lens retainer cap positions on beveled support posts to form an upper surface of the lens cavity. Lens haptics fit between the support posts to prevent rotational movement of the IOL in the lens package. Tightening flanges in the lens retainer cap engage in ramped catches in the inner perimeter of the configured cavity to secure the lens retainer cap to the configured cavity. Differently configured cavity interiors accept different configurations of posterior and anterior chamber lenses.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
244 words
An intraocular lens package for containment of an intraocular lens, the package comprising: a. a base; b. a configured cavity affixed to the upper surface of said base including a centrally located lens cavity for the support of an intraocular lens wherein said lens cavity includes a plurality of support posts, said support posts including beveled radiused support seats, said support posts being positioned vertically on a central configured rim wherein said lens cavity includes said central configured rim and a segmented disc supported by two or more semi-tubular struts, wherein said semi-tubular struts and said segemented disc extends inwardly from the inner radius of a circular support member to support said central configured rim, wherein a raised annular rim including ramped catches is positioned about said circular support member to form said lens cavity; and, c. a lens retainer cap including a gripping rim, a circular support member extending inwardly from the lower portion of said gripping rim to form an inner circular edge, an annular ring extending downwardly from said inner circular edge, a plurality of flanges extending downwardly and outwardly from the lower surface of said annular ring, said flanges bearing locking teeth upon an upper surface, a conical member located centrally within said annular ring, and a hole located centrally within said conical member wherein said lens retainer cap rotationally secures over and about said configured cavity and lens cavity for securement of an intraocular lens within said lens cavity.
Claim 2
Dependent Claim
244 words
An intraocular lens package for containment of an intraocular lens, the package comprising: a. a base; b. a configured cavity affixed to the upper surface of said base including a centrally located lens cavity for the support of an intraocular lens wherein said lens cavity includes a plurality of support posts, said support posts including beveled radiused support seats, said support posts being positioned vertically on a central configured rim wherein said lens cavity includes said central configured rim and a segmented disc supported by two or more semi-tubular struts, wherein said semi-tubular struts and said segemented disc extends inwardly from the inner radius of a circular support member to support said central configured rim, wherein a raised annular rim including ramped catches is positioned about said circular support member to form said lens cavity; and, c. a lens retainer cap including a gripping rim, a circular support member extending inwardly from the lower portion of said gripping rim to form an inner circular edge, an annular ring extending downwardly from said inner circular edge, a plurality of flanges extending downwardly and outwardly from the lower surface of said annular ring, said flanges bearing locking teeth upon an upper surface, a conical member located centrally within said annular ring, and a hole located centrally within said conical member wherein said lens retainer cap rotationally secures over and about said configured cavity and lens cavity for securement of an intraocular lens within said lens cavity.
Claim 3
Dependent Claim
29 words
The intraocular lens package of claim 1 wherein said beveled and radiused support seats position below said support post tops to support an intraocular lens in said lens cavity.
Claim 4
Dependent Claim
29 words
The intraocular lens package of claim 1 wherein said support posts limit downward travel of the conical member in said cap to provide for a close tolerance fit chamber.
Claim 5
Dependent Claim
33 words
The intraocular lens package of claim 1 wherein said segmented disc is ramped and slopes inwardly towards the center and inwardly towards said lens cavity for accommodation of posterior chamber intraocular lens loops.
Claim 6
Dependent Claim
28 words
The intraocular lens package of claim 1 wherein the conical member in the cap extends downwardly and inwardly toward said center hole for accommodation of posterior lens loops.
Claim 7
Dependent Claim
33 words
The intraocular lens package of claim 1 wherein spacing is provided for placement of a loop or loops between said support posts to limit rotational movement of an IOL within said lens cavity.
Claim 8
Dependent Claim
23 words
The intraocular lens package of claim 1 wherein said raised annular rim is not ramped to accommodate an intraocular lens with non-vaulted loops.
