  • Patent number: 9872762
    Abstract: An accommodating intraocular lens includes an optic portion a haptic portion and a backstop. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. The backstop provides support to the haptic so that bulk translation of the haptic is prevented in response to the forces applied by the capsular sac.

  • Patent number: 9855139
    Abstract: An apparatus for deploying an intraocular lens into an eye including a fluid delivery device that includes a fluid passageway extending to a proximal end of the fluid delivery device, the fluid passageway adapted to allow a fluid to flow therethrough from the proximal end of the fluid delivery device to within the fluid passageway, and a side vent that is not an intraocular lens delivery port, the side vent disposed proximal to an intraocular lens and adapted to vent air when fluid flows through the fluid passage, wherein the side vent is adapted to resist the flow of a viscoelastic material therethrough.

  • Patent number: 8992609
    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.

  • Patent number: 8454688
    Abstract: An accommodating intraocular lens is provided in which a deflectable lens element is anchored to a substrate along its optical axis to define a fluid filled space. Fluid-filled haptics disposed in fluid communication with the space vary the fluid volume in the space responsive to forces applied by the ciliary muscles, thereby causing the periphery of the lens element to deflect relative to the substrate and changing the optical power of the intraocular lens.
