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.

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.

Abstract: Intraocular lens loading devices, system, and methods of use. The device and systems can be used to load an intraocular lens into a cartridge, from which it can delivered into a patient's eye. The devices and systems can also be used to simply advance an intraocular lens through any type of loading or delivery device.
Abstract: An intraocular lens adapted to be implanted inside a capsular bag, comprising a peripheral portion comprising an anterior annular portion adapted to engage an anterior capsule portion, the anterior annular portion defining an anterior opening through which an optical axis passes, a posterior annular portion adapted to engage a posterior capsule portion, the anterior and posterior annular portions being adapted to keep the capsular bag open after implantation, and an optic portion disposed within the anterior opening and secured to and radially inward relative to the peripheral portion.
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.
Abstract: Delivery devices for delivering an ophthalmic device into an eye. In some embodiments the delivery devices are adapted to deliver an intraocular lens into an eye.

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.
