Abstract:
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, and wherein 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.
