Abstract
Embodiments of an intraocular lens are described. The intraocular lens includes a lens having a center and having positive or negative optical power and a pinhole mask formed on the lens. The pinhole mask includes one or more annular sections whose centers substantially coincide with the center of the lens, each of the one or more concentric annular sections having variable opacity, and a central section that is permanently transparent, the radius of the central section being adapted to allow the central section to act as a pinhole when the one or more concentric annular sections are made opaque.
Claims28
An intraocular lens comprising:
- a lens having a center and having positive or negative optical power;
- and
- a pinhole mask formed on the lens, the pinhole mask comprising:
- one or more annular sections concentrically aligned, each of the one or more annular sections having variable opacity, each of the one or more annular sections including a liquid crystal layer having an annular shape that encircles a central hole through the liquid crystal layer;
- and
- a central section that is permanently transparent, a radius of the central section being adapted to allow the central section to act as a pinhole when the one or more annular sections are made opaque, wherein the central hole in the liquid crystal layer of each of the one or more annular sections encircles the central section.

- one or more annular sections concentrically aligned, each of the one or more annular sections having variable opacity, each of the one or more annular sections including a liquid crystal layer having an annular shape that encircles a central hole through the liquid crystal layer;
- and
- a central section that is permanently transparent, a radius of the central section being adapted to allow the central section to act as a pinhole when the one or more annular sections are made opaque, wherein the central hole in the liquid crystal layer of each of the one or more annular sections encircles the central section;
- one or more sensors positioned on the lens;
- and
- a controller disposed on a peripheral part of the lens and electrically coupled to the one or more sensors and to the pinhole mask.
