Abstract

Abstract An intraocular lens which is vaulted from contact with the iris utilizing an optical portion having an optical plane. The optical lens is positioned in the eye by connecting a first relatively rigid member to the optical portion. A first member attached to the optical portion and oriented away from the optical plane second part is connected to the first part and orients toward the optical plane in relation to the first part. A second relatively flexible member connects to the second part of the first member to form an appendage unit.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 264 words
An intraocular lens for placement within an eye comprising: a. an optical portion having an optical plane; b. means for positioning said optical portion in the eye, said means comprising first and second appendage units, each of said first and second appendage units extending outwardly from and spaced from one another along one side of said optical portion, and third and fourth appendage units extending outwardly from and spaced from one another along another side of optical portion generally opposite said one side, each appendage unit including a first relatively rigid member depending from said optical portion, said first member including a first part connected to said optical portion and oriented away from said optical plane of said optical portion, said first part of said first member extending outwardly from said optical portion, said first member further including a second part connected to said first part and oriented, in relation to said first part, toward said optical plane said second part of said first member extending outwardly from said first part and from said optical portion, and, a second relatively flexible member connected to said second part of said first member and extending outwardly therefrom and outwardly in relation to said optical portion further than said first relatively rigid member, each relatively flexible member including an open loop defining a terminal end part for contacting eye tissue, said open loops of said first and second appendage units rotationally turned in opposite directions toward one another, and said open loops of said third and fourth appendage units rotationally turned in opposite directions toward one another.
Claim 2
Dependent Claim 264 words
An intraocular lens for placement within an eye comprising: a. an optical portion having an optical plane; b. means for positioning said optical portion in the eye, said means comprising first and second appendage units, each of said first and second appendage units extending outwardly from and spaced from one another along one side of said optical portion, and third and fourth appendage units extending outwardly from and spaced from one another along another side of optical portion generally opposite said one side, each appendage unit including a first relatively rigid member depending from said optical portion, said first member including a first part connected to said optical portion and oriented away from said optical plane of said optical portion, said first part of said first member extending outwardly from said optical portion, said first member further including a second part connected to said first part and oriented, in relation to said first part, toward said optical plane said second part of said first member extending outwardly from said first part and from said optical portion, and, a second relatively flexible member connected to said second part of said first member and extending outwardly therefrom and outwardly in relation to said optical portion further than said first relatively rigid member, each relatively flexible member including an open loop defining a terminal end part for contacting eye tissue, said open loops of said first and second appendage units rotationally turned in opposite directions toward one another, and said open loops of said third and fourth appendage units rotationally turned in opposite directions toward one another.
Claim 3
Dependent Claim 26 words
The intraocular lens of claim 1 in which said second part of said first members of each appendage unit lies substantially parallel to the optical plane.
