METHOD OF FORMING A MULTI-PIECE INSERT DEVICE WITH SEAL FOR OPHTHALMIC DEVICES

摘要

This invention discloses methods and apparatus for sealing and encapsulating components on and within a multi-piece insert. In some embodiments, an ophthalmic lens is cast molded from a silicone hydrogel and the component includes a sealed and encapsulated multi-piece insert portion.

主权项

1. A method of forming a multi-piece insert for an ophthalmic lens, the method comprising:
forming at least a first insert back curve piece; forming at least a first insert front curve piece; depositing a conductive material onto one or both of the first insert front curve piece and the first insert back curve piece; attaching an electronic component to one or both of the first insert front curve piece and the first insert back curve pieces, wherein the attachment is made to the conductive material; placing a first material to form a first seal upon a surface of either or both of the first insert front curve piece and the first insert back curve piece; and combining the first insert back curve piece with the first insert front curve piece to form a first ophthalmic insert piece, wherein the combining causes the first material to seal a first cavity interior to the combination of the first back curve piece and the first front curve piece.
