  • Patent number: 10613356
    Abstract: One aspect of the present disclosure relates to a remotely controllable lens device. The lens device can include a lens material and a circuit physically coupled to the lens material. The circuit can be configured to be powered based on an energy signal from a power source to perform a function (e.g., release of drug, generation of electromagnetic radiation, detection of electromagnetic radiation, and/or control of an optical refractive property). For example, the power source can be an external power source and/or an auto-powered source. The external power source can be, for example, a power source that utilizes synchronized magnetic flux phase coupling (e.g., WiTricity). The auto-powered source can be provided on-site (e.g., on-chip) using a harvesting system (e.g., solar-cell, photo-cell, piezoelectric, etc.

  • Patent number: 10524900
    Abstract: The present invention provides an accommodative intraocular lens (AIOL) system and method for improving accommodation with an intraocular lens. The method involves insertion into the capsular bag of a flexible optic holder comprising a plurality of haptics configured to allow the capsular bag to be sectioned at regular intervals following fusion of the capsular bag. The haptics of the optic holder are designed to allow maximum fusion of the anterior and posterior leaves of the capsular bag following placement of the optic holder in the capsular bag. Following introduction of the optic holder into the capsular bag, the natural or assisted process of fibrosis/fusion of the capsular bag occurs, thereby sealing and securely capturing the haptics within the capsular bag.

  • Patent number: 8992610
    Abstract: Many modern implantable ophthalmic devices include electronic components, such as electro-active cells, that can leak harmful substances into the eye and/or surrounding tissue. In the implantable ophthalmic devices disclosed herein, electronic components are hermetically scaled within cavities formed by bonding together two or more glass wafers. Bonding the glass wafers together with laser fusion bonding, pressure bonding, or anodic bonding creates a seal that leaks at a rate of less than about 5×10?12 Pa m3 s?1 when subjected to a helium leak test. Hermetically sealed feedthroughs formed of conductive material running through channels in the wafers provide electrical connections to components inside the sealed cavities. In some cases, the conductive material has a coefficient of thermal expansion (CTE) that is roughly equal to (e.g., within 10% of) the CTE of the glass wafers to minimize leakage due to thermally induced expansion and contraction of the conductive material and the glass wafer.

    Abstract: A method for modifying the refractive index of an optical, hydrogel polymeric material. The method comprises irradiating predetermined regions of an optical, polymeric material with a laser to form refractive structures. To facilitate the formation of the refractive structures the optical, hydrogel polymeric material comprises a photosensitizer. The presence of the photosensitizer permits one to set a scan rate to a value that is at least fifty times greater than a scan rate without the photosensitizer in the material, yet provides similar refractive structures in terms of the observed change in refractive index. Alternatively, the photosensitizer in the polymeric material permits one to set an average laser power to a value that is at least two times less than an average laser power without the photosensitizer in the material, yet provide similar refractive structures.

  • Publication number: 20140148899
    Abstract: Ophthalmic devices with dynamic electro-active elements offer variable optical power and/or depth of field that restore lost accommodation in individuals suffering from presbyopia or aphakia. An illustrative device senses physiological processes indicative of the accommodative response and actuates a dynamic electro-active element to provide the desired change in optical power and/or depth of field. The illustrative device includes two application-specific integrated circuits (ASICs) for processing the accommodative response and actuating the electro-active element: a high-voltage ASIC that steps up a low voltage from a power supply to a higher voltage suitable for actuating the electro-active element, and another ASIC that operates at low voltage (and therefore consumes little power) and controls the operating state of the high-voltage ASIC. Because each ASIC operates at the lowest possible voltage, the illustrative ophthalmic device dissipates less power than other ophthalmic devices.
