Intraocular lens system and method for power adjustment
First Claim
Patent Images
1. An intraocular lens comprising:
- a central optic portion for focusing light, the optic portion defining a first chamber;
a peripheral portion outward of the optic portion, the peripheral portion defining a second chamber;
a selected fluid media disposed within the first and second chambers; and
a microporous body portion intermediate the first and second chambers, the microporous body portion selectively providing fluid communication of the selected fluid media between the first and second chambers.

Abstract
An intraocular lens (IOL) that provides for optical power adjustment following its implantation, for example, for use in treating cataract patients. The lens body has first and second surface portions that bound at least one interior chamber or space that extends from the central optic portion to the lens periphery. The interior chamber or space has a microporous body that is intermediate inner and outer portions of the space. In one embodiment, the microporous body is capable of cooperating with an external Rf or light source to expose a charge to a charge-carrying fluid within the interior chamber. By this system, fluid flows are induced to alter the optical parameters of the lens.

18. An intraocular lens body comprising:
-
a central optic portion defining a first chamber; a peripheral portion defining a second chamber; a fluid media disposed in the first and second chambers, wherein at least one of the optic portion and the peripheral portion comprises a polymer that is adapted to permanently change in a cross-sectional dimension in response to light energy application thereto to transfer the fluid media between the peripheral and optic portions. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
