Abstract

Intraocular devices for use in and attached to the natural lens capsule of an eye are provided. The lens capsule may be maintained in a configuration to avoid post-operative changes that are deleterious to vision. Single or dual optic systems are provided, which may be accommodating. Combinations of devices to obtain dual optic systems are disclosed.

Claims

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.

2. The device of claim 1 further comprising a membrane joined to the ring and extending within the ring.

3. The device of claim 1 further comprising an optic disposed within the ring.

4. The device of claim 1 further comprising a split in the ring and a latch adapted to join the ring across the split.

5. The device of claim 1 wherein the groove comprises a pair of continuous walls.

6. The device of claim 1 wherein the groove comprises a plurality of tabs extending radially outward from the body of the ring.

7. The device of claim 1 further comprising one or more eyelets, the eyelets being disposed on the ring and adapted for receiving a suture.
