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.Type: GrantFiled: February 28, 2005Date of Patent: August 17, 2010Assignee: PowerVision, Inc.Inventor: John H. Shadduck

Patent number: 7753953Abstract: An accommodating intraocular lens system for implantation in a capsular bag of an eye includes an optic component comprising first and second light-transmitting lens elements that define a fluid-filled deformation chamber located between the first and second lens elements. The first and/or second lens elements have an elastic membrane adapted to deform in response to a change in pressure. The elastic membrane includes a first portion having a first deformation response and a second portion having a different second deformation response. The system also includes a refractive fluid filling the deformation chamber and at least one haptic member coupled to the optic component. The haptic member is configured for changing a hydrostatic pressure in the deformation chamber in response to muscle movement in the eye in order to deform the elastic membrane of the first and/or second lens elements, thereby changing the shape and the refractive characteristics of the optic component.Type: GrantFiled: March 26, 2008Date of Patent: July 13, 2010Inventor: Kingman Yee
