Abstract
Abstract An intraocular lens apparatus for insertion into a posterior chamber adjacent the iris of an eye. The apparatus includes a lens having a front face, a central portion and an outer periphery and a plurality of cantilevered clips. Each clip is mounted to the central portion, extends outwardly from the face and toward the periphery. The clips are adapted to secure the iris to the front face of the lens when the lens is positioned within the posterior chamber of the eye immediately behind the iris. A surgical tool includes a handle portion and a foot portion having a clip retaining surface which serves to maintain the lens on the tool when the lens is being positioned in the posterior of the eye. In one embodiment the clips are comprised of a resilient springy material which serves to bias the legs toward the face. In an alternate embodiment, the clips are comprised of a deformable, malleable material.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
83 words
An intraocular lens apparatus for insertion into a posterior chamber adjacent the iris of an eye, comprising: a lens having a front face, a central portion and an outer periphery; and a plurality of cantilevered clips, each mounted to said central portion and extending outwardly from said face and toward said periphery, said clips being adapted to secure the iris to the front face of said lens when said lens is positioned within the posterior chamber of the eye immediately behind the iris.
Claim 2
Dependent Claim
83 words
An intraocular lens apparatus for insertion into a posterior chamber adjacent the iris of an eye, comprising: a lens having a front face, a central portion and an outer periphery; and a plurality of cantilevered clips, each mounted to said central portion and extending outwardly from said face and toward said periphery, said clips being adapted to secure the iris to the front face of said lens when said lens is positioned within the posterior chamber of the eye immediately behind the iris.
Claim 3
Dependent Claim
30 words
An intraocular lens apparatus as recited in claim 1 wherein said face includes a plurality of recesses for respectively receiving the securing portion of each of said plurality of clips.
Claim 4
Dependent Claim
28 words
An intraocular lens apparatus as recited in claim 1 wherein said clip is comprised of a resilient material, said material serving to bias said clip toward said face.
Claim 5
Dependent Claim
30 words
An intraocular lens apparatus as recited in claim 3 wherein each clip includes a base portion mounted to said central portion, said base portion being rotatable about an axis therethrough.
Claim 6
Dependent Claim
31 words
An intraocular lens apparatus as recited in claim 4 wherein said central portion includes a plurality of apertures therethrough and wherein said base portions extend through corresponding ones of said apertures.
Claim 7
Dependent Claim
25 words
An intraocular lens apparatus as recited in claim 4 wherein each said base portion includes a flange portion for securing said clip to said lens.
Claim 8
Dependent Claim
31 words
An intraocular lens apparatus as recited in claim 1 wherein each said clip is comprised of a deformable, malleable material such that said clip may be formed into a predetermined shape.
Claim 9
Dependent Claim
27 words
An intraocular lens apparatus as recited in claim 7 wherein each said base portion includes flanges at its respective ends for securing said clip to said lens.
Claim 10
Dependent Claim
109 words
An intraocular lens apparatus as recited in claim 1 and further including in combination, a lens carrying tool for use in inserting said lens into the eye, said tool including a handle portion, and a foot portion, said foot portion having a lens engaging surface adapted to engage said front face, and means forming a clip retainer for attaching said lens to said foot portion and for retaining each said clip spaced from said face, whereby said tool may be used to selectively position said lens in the posterior chamber of the eye and may then be detached from said lens by moving said clips from said clip retainer.
Claim 11
Dependent Claim
153 words
An intraocular lens apparatus comprising in combination: a lens having a front face, a central portion and an outer periphery, and a plurality of cantilevered clips, each mounted to said central portion and extending outwardly from said face and toward said periphery, said clips being movable from an iris-receiving position to an iris engaging position; and a lens carrying tool including a handle portion and a foot portion, said foot portion having a face engaging surface for engaging said front face, and means forming a clip retainer for attaching said lens to said foot portion and for retaining said clips spaced from said face in said iris-receiving position whereby, said tool may be used to selectively position said lens in the posterior chamber of the eye and may then be detached from said lens by moving said clips from said iris-receiving position to said iris-engaging position thereby securing said lens to the iris.
Claim 12
Dependent Claim
153 words
An intraocular lens apparatus comprising in combination: a lens having a front face, a central portion and an outer periphery, and a plurality of cantilevered clips, each mounted to said central portion and extending outwardly from said face and toward said periphery, said clips being movable from an iris-receiving position to an iris engaging position; and a lens carrying tool including a handle portion and a foot portion, said foot portion having a face engaging surface for engaging said front face, and means forming a clip retainer for attaching said lens to said foot portion and for retaining said clips spaced from said face in said iris-receiving position whereby, said tool may be used to selectively position said lens in the posterior chamber of the eye and may then be detached from said lens by moving said clips from said iris-receiving position to said iris-engaging position thereby securing said lens to the iris.
Claim 13
Dependent Claim
37 words
An intraocular lens apparatus as recited in claim 10 wherein said foot portion includes a plurality of notches extending between said lens engaging surface and said clip retainer for receiving respective ones of said plurality of clips.
Claim 14
Dependent Claim
79 words
An intraocular lens apparatus as recited in claim 11 wherein said foot portion in plan view has a major axis and a minor axis, said major axis having a length greater than, and said minor axis having a length less than the length of a corresponding diameter of said central portion and wherein said plurality of clips lie in the periphery of said central portion such that the lens may be inserted into the posterior chamber of the eye.
Claim 15
Dependent Claim
28 words
An intraocular lens apparatus as recited in claim 11 wherein said notches lie on a circle having a diameter substantially equal to the diameter of said central portion.
Claim 16
Dependent Claim
33 words
An intraocular lens apparatus as recited in claim 13 wherein the distance between said notch and the outer boundary of said foot portion is less than the outwardly extending length of said clip.
Claim 17
Dependent Claim
86 words
An intraocular lens apparatus as recited in claim 10 wherein said foot portion includes first means responsive to an actuating force and operative to move said clip retainer away from said front face, and wherein said handle portion comprises means for actuating said first means, whereby actuation of said first means moves said clip retainer away from said front face, thus forcing said clips away from said clip retainer which thereby releases said lens from said tool and moves said clips into engagement with the iris.
Claim 18
Dependent Claim
51 words
An intraocular lens apparatus as recited in claim 15 wherein said handle portion comprises first and second lever arms configured as a lever, said first arm carrying said foot portion and said second arm carrying said first means, whereby movement of said lever arms toward one another actuates said first means.
