Intracapsular pseudophakic device
First Claim
Patent Images
1. An intraocular device for maintaining separation of an anterior capsule and a posterior capsule of an evacuated lens capsule of an eye, the lens capsule further having a formix and an anterior capsule opening, comprising:
- an optic; and
a plurality of deformable haptics attached to the optic at a proximate end of the haptics, the haptics having a selected response to a bending force so as to separate the anterior and the posterior capsule of the eye when the optic is disposed against the posterior capsule and the haptics are disposed in proximity to the posterior capsule, the formix and a portion of the anterior capsule.

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.

16. A multi-part intraocular lens, comprising:
-
a ring of flexible biocompatible material adapted to be placed in a capsulotomy in an eye, the ring comprising a body and a groove concentrically outside the body, the groove adapted to receive material at the periphery of the capsulotomy;
a plurality of cleats, the cleats disposed around the periphery of the ring; and
a lens body, the lens body comprising an optic and a plurality of apertures, the apertures being adapted and disposed so as to be placed around the cleats. - View Dependent Claims (17, 18, 19, 20, 21, 40)

22. 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 response to a bending 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 formix and the a portion of the posterior capsule. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)

33. A device to be placed in an anterior capsule opening of an eye, the anterior capsule opening having a periphery, comprising:
-
a ring and a membrane therewithin, the ring being adapted to form a sealing area between the ring and a surface of the anterior capsule;
a collar extending from the ring so as to receive a segment of the anterior capsule around the periphery of the anterior capsule opening; and
a tissue adhesive between the collar and the anterior capsule. - View Dependent Claims (34, 35)

36. A device to be placed in an anterior capsule opening of an eye, the anterior capsule opening having a periphery, comprising:
-
a ring and a membrane therewithin, the ring being adapted to form a sealing area between the ring and a surface of the anterior capsule, the sealing area being adapted for fluid communication with a conduit extending outside the capsule; and
a pinching arrangement in the ring to retain the anterior capsule within the ring after the sealing area is formed and the anterior capsule is forced into the pinching arrangement. - View Dependent Claims (37, 38)
