MULTI-PIECE ACCOMMODATING INTRAOCULAR LENS
An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with fold(s) extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes. A third lens component coupled to the first or second component provides additional optical power.
METHOD FOR PRODUCING AN ACCOMMODATIVE INTRAOCULAR LENS
A method for producing an accommodative intraocular lens includes providing first and second components and a support body with an interior space and open to the top, fastening the first component to the support body, generating pressure which is higher in the exterior space than in the interior space such that the first component deforms downward, producing an adhesive surface on the upper side of the first component and/or on the second component, applying a liquid to the first component from above into the latter's downwardly deformed region, the liquid at no time contacting the adhesive surface, fastening the second component to the first component with the adhesive surface, as a result of which the accommodative intraocular lens is formed and the liquid is encapsulated with the first component and the second component in a cavity arranged in the interior of the intraocular lens.
ACCOMMODATING INTRAOCULAR LENS DEVICE
An accommodating intraocular lens device is provided. The accommodating intraocular lens device comprises a base assembly and a power lens. The base assembly comprises a first open end, a second end coupled to a base lens, and a haptic surrounding a central cavity. The haptic may comprise an outer periphery, an inner surface and a height between a first edge and a second edge. The power lens is configured to fit within the central cavity. The power lens may comprise a first side, a second side, a peripheral edge coupling the first and second sides, and a closed cavity configured to house a fluid. The first side of the power lens may be positioned at a predetermined distance from the first edge of the haptic.

Contact lens-based methods to deliver power to intraocular devices
An eye-mountable device is provided that includes a battery or other local power source and that can wirelessly power one or more intraocular devices using power from the battery. The eye-mountable device could be provided as a contact lens. The eye-mountable device could provide power to an intraocular device by emitting radio frequency energy, time-varying electrical fields through the conductive medium of the eye, or optical energy. The intraocular device could include an electronic lens configured to provide a controllable optical power to the eye. The intraocular device could include sensors configured to detect accommodation forces exerted by muscles of the eye; such detected forces could be used to control an electronic lens of the intraocular device or an electronic lens of the eye-mountable device. The battery could be rechargeable and the eye-mountable device could be configured to receive power to recharge the battery.
Hydrophilic AIOL with bonding
An accommodating intraocular lens comprises a first lens component, a second lens component, and an adhesive between portions of the two lens components. The cured adhesive bonds the lens components to form a fluid chamber. The lens components are bonded to one another along a seam which extends circumferentially along at least a portion of the lens components. The lens components may comprise the same polymer material. The cured adhesive also comprises the polymer or a prepolymer of the polymer to provide increased strength. The polymer is hydratable such that the lens components and the cured adhesive therebetween can swell together to inhibit stresses between the lens components and the cured adhesive.
