Abstract: A surgical implant for a proximal carpal row replacement surgery employs a scanned image of each of the scaphoid, lunate and triquetrum bones for generating a unitary, homogeneous model defining a fused shape for implantation as the proximal carpal row. The implant utilizes a contralateral image of healthy bones of the patient for generating the replacement model, and employs shrink-wrap and smoothing processing to generate the unitary replacement. The resulting implant replaces the intercalary bone structures of the scaphoid, lunate and triquetrum with a single appliance, and is slideably engaged with the distal carpal row via a surgical tunnel and tethered by a resectioned tendon, ligament, or other connective member. The implant facilitates wrist function since the unitary implant replaces skeletal structures that are encapsulated by adjacent bones and frequently move as a unit, while eliminating gaps, voids and ligaments between the intercalary structure.

Abstract: A fluid lens assembly including a front rigid lens, a semi-flexible membrane that is adapted to be expanded from a minimum inflation level to a maximum inflation level, and a fluid layer therebetween.

Abstract: An intraocular implant (IOI) includes a lens structure with variable optical power, a sensor that detects an optical accommodation response, a rechargeable power storage device, a recharging interface, a wireless communication interface, and a controller. The controller can receive information from the sensor indicating an optical accommodation response, control the lens structure to vary the variable optical power based on the information received from the sensor, control the recharging interface to recharge the rechargeable power storage device, and further control the recharging interface to receive power for operation of the IOI, and transmit and receive information through the wireless communication interface.

Abstract: An accommodating contact lens comprises a variable focus optical module, which comprises an optical chamber and one or more eyelid engaging chambers coupled to the optical chamber with one or more extensions comprising channels extending between the optical chamber and the more eyelid engaging chambers. The module may comprise a self-supporting module capable of supporting itself prior to placement in a contact lens to facilitate placement prior to encapsulation in the contact lens. The module may comprise one or more optically transmissive materials, provides improved optical correction, and can be combined with soft contact lens materials such as hydrogels. In many embodiments, the module comprises a support structure extending between an upper membrane and a lower membrane in order to provide variable optical power accurately with decreased amounts distortion and improved responsiveness to eyelid induced pressure.

Abstract: A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways, and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.

The MCU may have sufficient internal memory so that little or no external volatile memory or RAM is used, for example, for image data buffering.

Abstract: A non-round fluid lens assembly includes a non-round rigid lens and a flexible membrane attached to the non-round rigid lens, such that a cavity is formed between the non-round rigid lens and the flexible membrane. A reservoir in fluid communication with the cavity allows a fluid to be transferred into and out of the cavity so as to change the optical power of the fluid lens assembly. In an embodiment, a front surface of the non-round rigid lens is aspheric. Additionally or alternatively, a thickness of the flexible membrane may be contoured so that it changes shape in a spheric manner when fluid is transferred between the cavity and the reservoir.
