Abstract
Abstract The present invention is a lens designed for implantation into the capsule of a human eye. The element forming the optic component is provided with supporting loops, the ends of which have been inserted into the periphery of said element, through holes being provided in said periphery. The loops are securely anchored in two capsular pockets after affected portions of the natural lens and a front part of the capsule, have been removed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
75 words
An intraocular lens implantable into the posterior chamber of a human eye without fixating sutures, comprising an optical lens body and at least a pair of loop shaped members fixed to the periphery of said lens body and extending outwardly from generally opposed sides thereof, one member being of U-shaped configuration and the other member being ovaloid, said ovaloid member being relatively radially inwardly resiliently deformable and said U-shaped member being relatively radially inwardly non-deformable.
Claim 2
Dependent Claim
75 words
An intraocular lens implantable into the posterior chamber of a human eye without fixating sutures, comprising an optical lens body and at least a pair of loop shaped members fixed to the periphery of said lens body and extending outwardly from generally opposed sides thereof, one member being of U-shaped configuration and the other member being ovaloid, said ovaloid member being relatively radially inwardly resiliently deformable and said U-shaped member being relatively radially inwardly non-deformable.
Claim 3
Dependent Claim
61 words
An intraocular lens according to claim 1, wherein said lens body has hole pairs formed therein for housing the ends of legs of said loop shaped members, one of said hole pairs being parallel for housing the legs of said U-shaped loop, the holes of the other pair converging inwardly for housing the ends of the legs of said ovaloid member.
Claim 4
Dependent Claim
94 words
An intraocular lens according to claim 1, wherein the said lens body has hole pairs formed therein for housing the ends of legs of said members, the distance, at the periphery of said lens body, between two holes forming the members of one pair for housing the leg ends of said U-shaped loop being relatively close together, at the periphery of said lens body, and the distance, at the periphery of said lens body between two holes forming the other pair for housing the leg ends of the ovaloid member being relatively far apart.
Claim 5
Dependent Claim
91 words
A method for the implantation without fixating sutures of an intraocular lens as set forth in claim 1 in the natural lens capsule of a human eye comprising the steps of perforating the anterior membrane of said natural lens capsule to provide a plurality of perforations defining a predetermined pattern, removing the affected natural lens leaving two lobes with a portion of the anterior membrane surrounded by the perforations, implanting the intraocular lens in the remaining part of said lens capsule and disposing the loops of said lens behind said lobes.
Claim 6
Independent Claim
163 words
A method for implantation without fixating sutures of an intraocular lens in the lens capsule of a human eye, comprising the steps of (a) perforating the anterior membrane of the natural lens capsule to provide a plurality of perforations defining a predetermined pattern; (b) removing both the affected natural lens portions and a portion of the natural lens capsule surrounding the perforations leaving a remainent portion having two lobes; (c) providing an intraocular lens having an optical body and at least a pair of loop shaped members fixed to the periphery of said body and extending outwardly from opposed sides, one loop member being of U-shaped configuration and the other member being ovaloid with said ovaloid member being relatively inwardly resiliently deformable and said U-shaped member being relatively radially inwardly non-deformable; (d) implanting the intraocular lens in the remainent portion of the natural lens capsule; and (e) inserting the loop members behind said lobes of the remainent portion of the natural lens capsule.
Claim 7
Independent Claim
