Abstract
An optical device comprising a lens configured to be disposed in an eye. The lens is configured to contact a sclera of the eye and have a clearance above a cornea of the eye when disposed in the eye. The lens comprises a back surface that comprises at least one non-symmetrical feature that is configured to engage a corresponding feature on the eye. The lens is configured to be rotationally stable in use based on the at least one non-symmetrical feature on the back surface of the lens.
Claims20
An apparatus comprising:
- a lens configured to be disposed on an eye, wherein the lens comprises:
- a front lens surface;
- a back lens surface configured to engage a feature of a sclera of the eye to provide rotational stability of the lens on the eye;
- and
- an optical axis, and
- wherein the optical axis is not aligned with a corneal apical axis of the eye.
A method of manufacturing a lens for disposition on an eye, comprising:
- identifying a corneal apical axis of the eye
- calculating characteristics of a back surface of the lens having an optical axis not aligned with the corneal apical axis of the eye and a portion configured to engage a feature of a sclera of the eye to provide rotational stability of the lens on the eye;
- calculating characteristics of a front surface of the lens having an optical axis not aligned with the corneal apical axis of the eye;
- and
- generating a lens design file for controlling a manufacturing device to manufacture the lens at least according to the calculated characteristics of the back surface of the lens.
An apparatus comprising:
- a front lens surface;
- a back lens surface configured to engage a feature of a sclera of an eye to provide rotational stability of the lens on the eye;
- a visual axis;
- and
- an optical axis,
- wherein the optical axis is not aligned with a corneal apical axis of the eye, and
- wherein the visual axis is aligned with the optical axis.
