First Claim
Patent Images
1. An intraocular device comprising:
- a ring of flexible biocompatible material adapted to be placed in a capsulotomy, the ring comprising a body and a groove concentrically outside the body, the groove adapted to receive material at the periphery of the capsulotomy; and
a plurality of deformable haptics rigidly attached to the ring at a proximate end of the haptics, the haptics having a selected length and a selected response to a being force so as to separate an anterior and a posterior capsule of an eye when the haptics are disposed in proximity to the anterior capsule, the fornix and a portion of the posterior capsule, thereby preventing collapse of a lens capsule, said selected length and selected response to a bending force capable of extending out of the plane of the ring and from the anterior capsule to the posterior capsule in contact along the surface of the capsule.
