1. An implantable intraocular lens (IOL) comprising:

  • a first substrate having a hermetically sealed feedthrough that provides a conductive path for electrical communication from a first side of the first substrate to a second side of the first substrate;

    a second substrate bonded to the first side of the first substrate to at least partially define a hermetically sealed cavity;

    a third substrate bonded to the second side of the first substrate to define the hermetically sealed cavity;

    an electronic component within the hermetically sealed cavity and in electrical communication with the conductive path provided by the hermetically sealed feedthrough;

    an inductive antenna coil;

    at least one battery; and

    an electro-active element in electrical communication with the electronic component via the hermetically sealed feedthrough;

    wherein each of the first, second, and third substrates comprises a glass wafer,wherein the electronic component includes a processor,wherein the electro-active element includes a liquid crystal material, andwherein the hermetically sealed feedthrough comprises a channel that connects the first and second sides of the first substrate and a conductive material within the channel to provide the conductive path.
