ABSTRACT:
An intra-ocular lens for implanting into the posterior capsule after cataract extraction, has a pair of sinuous haptics having greater flexibility near their roots than at their distal ends. A long arcuate distal segment of each haptic espouses the internal radius of the posterior capsule over an arc of at least 15 degrees. Both haptics have a slight backward slant. The haptics facilitate the implantation and retention of the lens.
