Abstract
Abstract An implantable artificial intraocular bipod lens comprising a medial light-focusing lens body having position fixation elements connected thereto. The fixation elements comprise a pair of straight elongated relatively thin and narrow legs extending tangentially in opposite directions from opposite sides of the lens body and lying along generally parallel lines. A relatively thin and narrow arcuate foot is located at the end of each of the legs. Each of the feet is longer and narrower than the width of the leg and preferably thicker than the leg. The feet extend obliquely in opposite directions. Preferably a suture/manipulation hole is provided in at least one of the legs spaced inwardly from the foot.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
168 words
An implantable artificial intraocular bipod lens comprising: a medial generally circular light-focusing lens body, position fixation elements connected to and one-piece with said lens body, said fixation elements including: (a) a pair of generally straight and elongated relatively flat semi-rigid thin and narrow legs, said legs: (1) extending along substantially tangential lines in opposite directions from opposite diametric areas of the lens body, and, (2) extending outwardly from said lens body in spaced parallel relation, (b) a relatively thin and narrow flat pad-like foot at the end of and one-piece with each of said legs, each said foot: (1) extending in an oblique direction with respect to its connected leg, (2) having a length in the said oblique direction greater than the width of the associated leg, and, (3) extending in an opposite direction from the other said foot and away therefrom and also from said lens body, thereby to space the distal ends of the feet further from each other than the spaced relation of said legs.
Claim 2
Dependent Claim
168 words
An implantable artificial intraocular bipod lens comprising: a medial generally circular light-focusing lens body, position fixation elements connected to and one-piece with said lens body, said fixation elements including: (a) a pair of generally straight and elongated relatively flat semi-rigid thin and narrow legs, said legs: (1) extending along substantially tangential lines in opposite directions from opposite diametric areas of the lens body, and, (2) extending outwardly from said lens body in spaced parallel relation, (b) a relatively thin and narrow flat pad-like foot at the end of and one-piece with each of said legs, each said foot: (1) extending in an oblique direction with respect to its connected leg, (2) having a length in the said oblique direction greater than the width of the associated leg, and, (3) extending in an opposite direction from the other said foot and away therefrom and also from said lens body, thereby to space the distal ends of the feet further from each other than the spaced relation of said legs.
