  • Patent number: 3994027
    Abstract: The invention is a prepupillary lens which may be surgically implanted into a human eye. The lens may be either a two-loop lens or a four-loop lens. The two-loop lens has a convex surface and a planar surface, into which a pair of posterior loops are embedded and fused therein. The four-loop lens is similar to the two-loop lens, but it also includes two pairs of parallel bores in the lens disposed in a plane between the convex surface and the planar surface and aligned with the posterior loops and a pair of anterior loops inserted into the bores and fused therein.
