Techniques and mechanisms for providing an eye-mountable device including an accommodation actuator. In an embodiment, fabrication of the eye-mountable device includes sealing layers of enclosure material to form a lens enclosure comprising a pinch-off region where the layers of enclosure material physically contact one another. The accommodation actuator includes a liquid crystal layer disposed between the layers of enclosure material in a central region around which the pinch-off region extends. In another embodiment, electrodes are disposed in the central region each between the liquid crystal layer and a respective one of the layers of enclosure material. The liquid crystal layer isolates the electrodes from one another in the central region.

Embodiments are disclosed of an eye-mountable device (EMD) including a lens enclosure including an anterior layer and a posterior layer sealed to the anterior layer. An anterior electrode is disposed within the lens enclosure on a concave side of the anterior layer, a posterior electrode is disposed within the lens enclosure on a convex side of the posterior layer, and an electrochromic element is disposed across a central region of the lens enclosure, wherein the electrochromic element separates the anterior electrode from the posterior electrode within the central region.

Device and methods for sealing and encapsulation for biocompatible energization elements are described. In some examples, the device and methods for sealing and encapsulation for biocompatible energization elements involve heat welding, laser welding, or both where a laminar structure is enclosed by a polymer film capable of sealing. In some examples, a field of use for the apparatus and methods may include any biocompatible device or product that requires energization elements.

An electronic device can comprise a first electronic module; a second electronic module; and a hermetic electric interconnect to hermetically couple them. The hermetic electric interconnect can comprise a bottom metal layer; a bottom insulating layer, deposited on the bottom metal layer to insulate the bottom metal layer; an interconnect metal layer, deposited on the bottom insulating layer, and deposited to form a bottom sealing ring; and patterned to form electrical connections between contact pads, and to form a middle sealing ring; a patterned top insulating layer, deposited on the interconnect metal layer to insulate the interconnect metal layer; and patterned to form feedthrough holes; and a top metal layer, deposited on the top insulating layer to start forming contacts by filling the feedthrough holes; and patterned to complete forming contacts through the feedthrough holes, to form a separate barrier layer, and to complete forming the top sealing ring.

An apparatus may include a mounting structure configured to removably mount a concave surface of a device. The mounting structure may have a convex mounting surface that corresponds to the concave surface of the device. The device may have a convex surface opposite the concave surface. The apparatus may also include a base structure that has a flat surface. The apparatus may also include a support structure coupled to the base structure and the mounting structure. The support structure may be configured to align the mounting structure at a given angle such that a target area on the convex surface of the device is substantially parallel to the flat surface of the base structure when the device is mounted on the mounting structure.

This invention discloses methods and apparatus for providing a variable optic insert into an ophthalmic lens. A liquid crystal layer may be used to provide a variable optic function and in some examples, an alignment layer for the liquid crystal layer may be patterned in a cycloidally dependent manner. The patterning may allow for a polarization dependent lens in some examples. An energy source is capable of powering the variable optic insert included within the ophthalmic lens. In some examples, an ophthalmic lens is cast-molded from a silicone hydrogel. The various ophthalmic lens entities may include electroactive liquid crystal layers to electrically control optical characteristics.

Systems and methods for manufacturing electro-active lenses including a peripheral edge, a discrete electro-active region, and at least two substrates. The at least two substrates include a layer of a transparent conductive material, that is laser cut to isolate regions required for establishing an electrical connection between the peripheral edge of the lens, from regions not required for establishing an electrical connection. Isolating the regions of the transparent conductive material required for establishing an electrical connection may include cutting patterns around an electrode of each of the substrates. The regions not required for establishing an electrical connection may be further cut into sections, which may be substantially band-shaped.

Methods and apparatuses for providing a variable optic insert into an ophthalmic lens as set forth. An energy source is capable of powering the variable optic insert included within the ophthalmic lens. In some embodiments, an ophthalmic lens is cast-molded from a silicone hydrogel.
