Abstract
Abstract An intraocular lens for positioning in the posterior chamber of the eye having a plastic lens body supported by first and second resilient spring-like support loops extending from opposite sides of the peripheral edge of the lens body; in use the support loop is preferably resiliently compressed against the equatorial region of the lens capsule of the eye from which the natural lens has been removed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
156 words
An intraocular lens for positioning in the posterior chamber of the eye comprising a lens body and first and second support members, characterized in that said first and second support members extending from the lens body for engaging the outer portion of the posterior chamber of the eye, at least one of said support members comprising a resilient spring-like support loop extending outwardly from the periphery of said lens body, said support loop having first and second end portions attached to the lens body at first and second attachment locations and being dimensioned and shaped to engage the outer portion of the posterior chamber of the eye with an outward radial force when positioned therein so that the outer contact portion of said resilient loop is deflected inwardly from the normal relaxed position by the outer portion of the posterior chamber of the eye to provide the support for the lens body in the posterior chamber.
Claim 2
Dependent Claim
156 words
An intraocular lens for positioning in the posterior chamber of the eye comprising a lens body and first and second support members, characterized in that said first and second support members extending from the lens body for engaging the outer portion of the posterior chamber of the eye, at least one of said support members comprising a resilient spring-like support loop extending outwardly from the periphery of said lens body, said support loop having first and second end portions attached to the lens body at first and second attachment locations and being dimensioned and shaped to engage the outer portion of the posterior chamber of the eye with an outward radial force when positioned therein so that the outer contact portion of said resilient loop is deflected inwardly from the normal relaxed position by the outer portion of the posterior chamber of the eye to provide the support for the lens body in the posterior chamber.
Claim 3
Dependent Claim
118 words
The lens of Claim 1 further characterized that each of said first and second support members comprise a resilient spring-like support loop extending outwardly from the periphery of said lens body, each said support loop having first and second end portions attached to the lens body at first and second attachment locations and being dimensioned and shaped to engage the outer portion of the posterior chamber of the eye with an outward radial force when positioned therein so that the outer contact portion of said resilient loop is deflected inwardly from the normal relaxed position by the outer portion of the posterior chamber of the eye to provide the support for the lens body in the posterior chamber.
Claim 4
Dependent Claim
69 words
The lens of Claim 1 or 2 further characterized that said support loop includes a first support leg extending between the first end portion and the outer contact portion, said support loop includes a second support leg extending between the second end portion and the outer contact portion and the first and second end portions of said support loop extend inwardly from the peripheral edge of the lens body.
Claim 5
Dependent Claim
46 words
The lens of Claim 3 further characterized that the first support leg is curved, said outer contact portion is curved, and said second support leg is curved and said first and second support legs of said loop outwardly diverge from said first and second end portions.
Claim 6
Dependent Claim
26 words
The lens of Claim 4 further characterized that said support loop is foot-shaped with the ankle portion of the foot being attached to the lens body.
Claim 7
Dependent Claim
25 words
The lens of Claim 2 further characterized that said support loops are oppositely disposed on said lens body and oriented cylindrically in a like manner.
Claim 8
Dependent Claim
140 words
An intraocular lens for positioning in the lens capsule of the eye comprising a lens body and first and second support members, characterized in that said first and second support members extending from the lens body for engaging the lens capsule, at least one of said support members comprising a resilient spring-like support loop extending outwardly from the periphery of said lens body, said support loop having first and second end portions attached to the lens body at first and second attachment locations and being dimensioned and shaped to engage the outer equatorial area of the lens capsule with an outward radial force when positioned therein so that the outer contact portion of said resilient loop is deflected inwardly from the normal relaxed position by the lens capsule to provide the support for the lens body in the lens capsule.
Claim 9
Dependent Claim
140 words
An intraocular lens for positioning in the lens capsule of the eye comprising a lens body and first and second support members, characterized in that said first and second support members extending from the lens body for engaging the lens capsule, at least one of said support members comprising a resilient spring-like support loop extending outwardly from the periphery of said lens body, said support loop having first and second end portions attached to the lens body at first and second attachment locations and being dimensioned and shaped to engage the outer equatorial area of the lens capsule with an outward radial force when positioned therein so that the outer contact portion of said resilient loop is deflected inwardly from the normal relaxed position by the lens capsule to provide the support for the lens body in the lens capsule.
Claim 10
Dependent Claim
109 words
The lens of Claim 7 further characterized that each of said first and second support members comprise a resilient spring-like support loop extending outwardly from the periphery of said lens body, each said support loop having first and second end portions attached to the lens body at first and second attachment locations and being dimensioned and shaped to engage the outer equatorial region of the lens capsule with an outward radial force when positioned therein so that the outer contact portion of said resilient loop is deflected inwardly from the normal relaxed position by the lens capsule to provide the support for the lens body in the lens capsule.
Claim 11
Dependent Claim
24 words
The lens of Claim 8 further characterized that said support loops are oppositely disposed on said lens body and oriented cylindrically in alike manner.
