Abstract
Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for reducing dysphotopsia effects, such as haloes and glare. Exemplary ophthalmic lenses can include an optic having a central region disposed about an optical axis and a peripheral region extending outward from the central region, with a diffractive achromat positioned on the peripheral region, and the central region lacking an achromat, and a base power for distance of the central region being the same as a base power for distance of the peripheral region.
Claims20
An ophthalmic lens comprising:
- an optic having a central region disposed about an optical axis and a peripheral region extending outward from the central region, wherein a diffractive achromat is positioned on the peripheral region, and the central region lacks an achromat, and wherein a base power for distance of the central region is the same as a base power for distance of the peripheral region.
A method comprising:
- fabricating an optic for an ophthalmic lens, the optic having a central region disposed about an optical axis and a peripheral region extending outward from the central region, wherein a diffractive achromat is positioned on the peripheral region, and the central region lacks an achromat, and wherein a base power for distance of the central region is the same as a base power for distance of the peripheral region.
A system for fabricating an ophthalmic lens, the system comprising:
- a processor configured to determine at least a portion of a profile of an optic having a central region disposed about an optical axis and a peripheral region extending outward from the central region, wherein a diffractive achromat is positioned on the peripheral region, and the central region lacks an achromat, and wherein a base power for distance of the central region is the same as a base power for distance of the peripheral region;
- and
- a manufacturing assembly that fabricates the optic based on the profile.
