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.
