Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
59 words
An iris fixation intraocular lens comprising an optical portion having a support portion on each side adapted to attach to eye tissue, at least one said side support portion comprising a pair of flat, flexible, normally abutting pincer-like arms adapted to pinch and fixate a portion of one surface only of iris tissue without penetrating to said other surface.
Claim 2
Dependent Claim
59 words
An iris fixation intraocular lens comprising an optical portion having a support portion on each side adapted to attach to eye tissue, at least one said side support portion comprising a pair of flat, flexible, normally abutting pincer-like arms adapted to pinch and fixate a portion of one surface only of iris tissue without penetrating to said other surface.
Claim 3
Dependent Claim
67 words
An iris fixation intraocular lens comprising an optical portion adapted to be positioned in the anterior chamber of the eye, one side support portion comprising a pair of flat, flexible, normally abutting pincer-like arms adapted to pinch and fixate a portion of the anterior surface only of iris tissue without penetrating to the posterior surface and a second side support portion adapted to attach to eye tissue.
Claim 4
Dependent Claim
67 words
An iris fixation intraocular lens comprising an optical portion adapted to be positioned in the anterior chamber of the eye, one side support portion comprising a pair of flat, flexible, normally abutting pincer-like arms adapted to pinch and fixate a portion of the anterior surface only of iris tissue without penetrating to the posterior surface and a second side support portion adapted to attach to eye tissue.
Claim 5
Dependent Claim
103 words
An iris fixation intraocular lens comprising an optical portion adapted to be positioned in the anterior chamber of the eye, one side support portion comprising a pair of flat, flexible, normally abutting pincer-like arms adapted to pinch and fixate a portion of the anterior surface only of iris tissue without penetrating said tissue to the posterior surface and a second side support portion which is an extension having an orifice adapted for suturing to the relatively non-movable portion of the iris; said lens being characterised in that its entire structure is adapted to be spaced completely within the anterior chamber of the eye.
Claim 6
Dependent Claim
103 words
An iris fixation intraocular lens comprising an optical portion adapted to be positioned in the anterior chamber of the eye, one side support portion comprising a pair of flat, flexible, normally abutting pincer-like arms adapted to pinch and fixate a portion of the anterior surface only of iris tissue without penetrating said tissue to the posterior surface and a second side support portion which is an extension having an orifice adapted for suturing to the relatively non-movable portion of the iris; said lens being characterised in that its entire structure is adapted to be spaced completely within the anterior chamber of the eye.
Claim 7
Dependent Claim
81 words
An iris fixation intraocular lens comprising an optical portion adapted to be positioned within the anterior chamber of the eye, one side support portion comprising a pair of flat, flexible, normally abutting pincer-like arms adapted to pinch and fixate a portion of the anterior surface only of iris tissue without penetrating to the posterior surface and a second side support portion which has a loop adapted to extend to the pupillary aperture so as to be positionable posteriorly to the iris.
Claim 8
Dependent Claim
81 words
