Adjustable ophthalmic devices, systems, and methods of adjustment
Adjustable ophthalmic devices, systems including adjustable ophthalmic devices, and methods of adjusting an optical power of an ophthalmic device are described. In an embodiment, the ophthalmic devices include a body including an inner surface defining an aperture through the body, wherein the inner surface includes a feature selected from a sharp surface feature, a layer on at least a portion of the inner surface having a surface energy different than a surface energy of the inner surface, and a combination thereof. In an embodiment, the ophthalmic device includes two immiscible liquids disposed in the aperture defining a meniscus, wherein a curvature of the meniscus is defined at least in part by a position of an interface between the layer and the inner surface, a position of the sharp surface feature, or combination thereof.
1. An ophthalmic device comprising:
a body including an inner surface defining an aperture through the body, wherein the inner surface includes a layer on at least a portion of the inner surface having a surface energy different than a surface energy of the inner surface; and
two immiscible liquids disposed in the aperture defining a meniscus, wherein a curvature of the meniscus is defined at least in part by a position of an interface between the layer and the inner surface,
wherein the ophthalmic device has a base optical power,
wherein the layer is reconfigurable to adjust the base optical power,
wherein the layer is wet by a first liquid of the two immiscible liquids and is not wet by a second liquid of the two immiscible liquids, and
wherein the inner surface is wet by the second liquid and is not wet by the first liquid.
2. The ophthalmic device of claim 1 , wherein the layer is configured to ablate upon illumination with laser light.
3. The ophthalmic device of claim 1 , wherein the layer includes a phase-change material shaped to expose a portion of the inner surface upon transitioning from a first phase to a second phase.
4. The ophthalmic device of claim 1 , further comprising:
a plurality of circuits embedded in the layer; and
a controller operably coupled to the plurality of circuits including logic that when executed by the controller causes the ophthalmic device to perform operations including:
applying a voltage to one or more of the plurality of circuits sufficient to ablate a portion of the layer adjacent to the one or more of the plurality of circuits.
5. The ophthalmic device of claim 1 , wherein the layer is configured to decrease in volume upon illumination with laser light.
6. The ophthalmic device of claim 1 , further comprising a base lens having a static optical power coupled to the body.
7. The ophthalmic device of claim 1 , wherein the curvature of the meniscus is further defined by a feature selected from the group consisting of a shape of the body, a shape of interface between the layer and the inner surface, relative volumes of the two immiscible liquids, and combinations thereof.
8. A system comprising:
an ophthalmic device including:
a body including an inner surface defining an aperture through the body, wherein the inner surface includes a layer on at least a portion of the inner surface having a surface energy different than a surface energy of the inner surface; and
two immiscible liquids disposed in the aperture defining a meniscus, wherein a curvature of the meniscus is defined at least in part by a position of an interface between the layer and the inner surface, wherein the layer is wet by a first liquid of the two immiscible liquids and is not wet by a second liquid of the two immiscible liquids, and wherein the inner surface is wet by the second liquid and is not wet by the first liquid;
a laser; and
a controller operably coupled to the laser including logic that when executed by the ophthalmic device causes the system to perform operations including:
illuminating a portion of the layer with laser light from the laser, wherein illuminating the portion of the layer includes illuminating the portion of the layer with laser light sufficient to ablate the portion of the layer, thereby adjusting the curvature of the meniscus defined by the two immiscible liquids.
