Abstract
Abstract An improved intraocular lens mounting system for an Iris Clip type of lens. The lens has haptical portions extending laterally from the edges of the lens transversely to the optic axis of the lens. Fibrous material such as Dacron is attached to the outer edges of the haptical portions and provide bases into which the tissue of the iris can grow so as to form a firm anchor for the lens. The lens may also have two or more attached loops projecting in a plane generally parallel to the plane of the lens and to the haptical portions. The loops may be coated or encased in a sleeve of fibrous material and hold the lens in place with respect to the iris until tissue growth into the Dacron material is accomplished.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
87 words
An artificial intraocular lens system adapted to be implanted within a living eye immediately adjacent the iris of the eye and comprising: a plastic optical lens portion formed with a laterally extending haptical portion from said lens portion; and attachment means including a biologically tolerable fibrous material mounted on the outer periphery of said haptical portion and adapted to contact the iris of the eye so that tissue growth of the iris into the fibrous material can occur for permanently anchoring said lens system within the eye.
Claim 2
Dependent Claim
87 words
An artificial intraocular lens system adapted to be implanted within a living eye immediately adjacent the iris of the eye and comprising: a plastic optical lens portion formed with a laterally extending haptical portion from said lens portion; and attachment means including a biologically tolerable fibrous material mounted on the outer periphery of said haptical portion and adapted to contact the iris of the eye so that tissue growth of the iris into the fibrous material can occur for permanently anchoring said lens system within the eye.
Claim 3
Dependent Claim
33 words
The lens system of claim 1 including temporary attachment means for locating said lens system with respect to the pupillary aperture of the iris until tissue growth into the fibrous material is accomplished.
Claim 4
Dependent Claim
22 words
The lens system of claim 2 wherein said temporary attachment means is at least one hook formed of a biologically absorbable filament.
Claim 5
Dependent Claim
54 words
The lens system of claim 2 including at least one integral, laterally projecting loop for mounting through the pupillary aperture of the iris and effective to hold said optical lens portion and said haptical portion in contact with the anterior surface of the iris so that tissue growth into said fibrous material can occur.
Claim 6
Dependent Claim
15 words
The lens system of claim 1 wherein: said fibrous material is comprised of Dacron polyester.
Claim 7
Dependent Claim
46 words
The lens system of claim 2 wherein said temporary attachment means is a circular loop attached to said lens portion by at least two axially extending and parallel pins, with said loop being mounted coaxially with and parallel to the plane of said optical lens portion.
Claim 8
Dependent Claim
93 words
An artificial intraocular lens system adapted to be implanted within a living eye immediately adjacent the iris of the eye and comprising: a plastic optical lens portion formed with at least one integral, laterally projecting loop adapted to be mounted through the pupillary aperture of the iris and effective when mounted to contact one surface of the iris; and a sleeve of biologically tolerable fibrous material mounted on the outer periphery of said loop and into which tissue of the iris can grow so as to anchor the lens portion within the eye.
Claim 9
Dependent Claim
93 words
An artificial intraocular lens system adapted to be implanted within a living eye immediately adjacent the iris of the eye and comprising: a plastic optical lens portion formed with at least one integral, laterally projecting loop adapted to be mounted through the pupillary aperture of the iris and effective when mounted to contact one surface of the iris; and a sleeve of biologically tolerable fibrous material mounted on the outer periphery of said loop and into which tissue of the iris can grow so as to anchor the lens portion within the eye.
