Abstract
An ophthalmic lens may comprise a posterior optic surface, an anterior optic surface, and an optic edge between the posterior optic surface and the anterior optic surface, wherein the optic edge forms a substantially circular perimeter having a thickness that varies periodically. The thickness of the optic edge may vary periodically for at least two cycles. Additionally, or alternatively, the ophthalmic lens may comprise an optic skirt coupled to the optic edge. The optic skirt can be configured to inhibit transmission of light around the optic edge.
Claims35
An ophthalmic lens for implanting into an eye, the ophthalmic lens comprising:
- a single optic having a posterior optic surface and an anterior optic surface;
- and
- an optic edge that couples the posterior optic surface and the anterior optic surface, the optic edge forming a substantially circular perimeter around the single optic and having a thickness that varies periodically for at least two cycles;
- wherein the thickness is oriented substantially parallel to an optical axis of the ophthalmic lens.
The ophthalmic lens of any preceding claim, wherein:
- the anterior optic surface comprises a central optic and a peripheral optic.
A lens for implanting into an eye, the lens comprising:
- a single optic having a posterior optic surface and an anterior optic surface;
- and
- an optic edge that couples the posterior optic surface and the anterior optic surface, the optic edge having a thickness that varies between at least two peaks and at least two troughs;
- wherein the thickness is oriented substantially parallel to an optical axis of the lens.
An ophthalmic lens for implanting into an eye, the ophthalmic lens comprising:
- a single central optic;
- and
- a peripheral optic disposed concentrically around the central optic, the peripheral optic comprising a posterior optic surface, an anterior optic surface, and an optic edge that couples the posterior optic surface and the anterior optic surface;
- wherein the anterior optic surface undulates so that the optic edge has a thickness that varies and;
- wherein the thickness is oriented substantially parallel to an optical axis of the ophthalmic lens.
