    摘要： 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.

    摘要： Ophthalmic lenses are described including a deformable layer and a deformable membrane disposed opposite the deformable layer. The lens is configured with at least two regions of adjustable optical power, such as by using a patterned electrode which is used to drive the membrane move axially along an optical path of the lens. A surface of the deformable layer is configured to expand and/or contract based on movement of the membrane along the optical path of the lens, such as by bonding one side of the deformable layer to the membrane and bonding the other side to a fixed optical element layer.
