    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： A sensor system includes at least two sensors for distinguishing accommodative stimuli from changes in ambient lights levels and task-induced changes in the pupil diameter. When implanted, the first sensor is disposed completely within the pupil; even when fully constricted, the pupil does not occlude the first sensor, allowing the sensor to make precise measurements of ambient luminous flux levels. The pupil occludes part of the second sensor's active area(s) as the pupil dilates and constricts. As a result, the second sensor measures both ambient luminous flux and pupil diameter. A processor estimates the pupil diameter and determines whether it's changing in response to accommodative stimuli or other factors by comparing to predetermined values. The sensor system sends a signal to an optical component, which in turn can respond by changing optical power to focus for near vision upon detection of accommodative stimuli.

    摘要： Astigmatism is an optical aberration that displaces the eye's vertical focal plane with respect to its horizontal focal plane. This displacement in focal planes, which may be caused by an irregularly shaped cornea and/or crystalline lens, causes images to appear blurry. Astigmatism can be corrected by implanting an optic, such as section of a spherical lens, whose projection onto a plane perpendicular to the optical axis is noncircular (e.g., rectangular or elliptical). Because the optic is noncircular, it provides more optical power along one axis than along another axis. As a result, it introduces an astigmatism that can be used to offset or compensate the eye's corneal and/or lenticular astigmatism when aligned properly with respect to the principal meridians of the cornea and/or crystalline lens.

    摘要： Implantable ophthalmic devices with aspheric lenses and dynamic electro-active elements offer excellent depth of field and image quality while providing high optical throughput. An exemplary implantable ophthalmic device includes an aspheric lens with a negative spherical aberration that varies with radius. The aspheric lens can have peak optical powers at its geometric centers surrounded by a region of varying optical power (with varying slope) that extends radially from its center. When implanted, these aspheric lenses provide an incremental optical power that varies as a function of pupil diameter, which changes with object distance, for viewing far, intermediate, and near objects. The aspheric lens may also bonded or integrally formed with a spherical lens that provides fixed optical power for viewing far objects and/or a dynamic electro-active element that with two or more states (e.g., on and off) for increasing the effective optical power when viewing near objects.

    摘要： Aspects of the present invention provide progressive addition lenses (PALs) and techniques for designing PALs that result in improved visual performance for the wearer. PALs of the present invention can have vision zones with widths that are more in line with the actual or functional sizes used by wearers. PALs of the present invention can also introduce controlled amounts of unwanted astigmatism into one or more vision zones. By allowing vision zones to include manageable levels of astigmatism, the resulting PAL can avoid the harsh build-up of astigmatism typically found in conventional PALs at the periphery of the channel and viewing zones. Further, PALs of the present invention can be designed using a merit function to achieve an optimized iterative design that accounts for astigmatism vector orientation and not simply astigmatism magnitude as is the case with conventional PAL design.

    摘要： Aspects of the present invention provide a lens comprising a non-rotationally symmetric aspheric optical element, surface or feature and a rotationally symmetric aspheric optical element, surface or feature. The non-rotationally symmetric aspheric optical feature can be a progressive power region. The non-rotationally symmetric aspheric optical feature and rotationally symmetric aspheric optical feature can be in optical communication when located on different surfaces of a lens or can be collapsed to occupy a single surface of a lens. The non-rotationally symmetric aspheric optical feature and rotationally symmetric aspheric optical feature can each contribute to the add power of a lens. Distortion (e.g., astigmatism) of a lens of the present invention can be reduced (e.g., globally and/or locally) by optically combing the non-rotationally symmetric aspheric optical feature with the rotationally symmetric aspheric optical feature. Accordingly, the effective or useable vision zones of a lens of the present invention can be increased.
