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 including a diffractive achromat configured to direct light to a common focus, with individual zones of the diffractive achromat directing light to the common focus in at least two different diffractive orders utilizing at least two different diffractive powers.

1-17. (canceled)
A method comprising:
- fabricating an optic for an ophthalmic lens, the optic including a diffractive achromat configured to direct light to a common focus, with individual zones of the diffractive achromat directing light to the common focus in at least two different diffractive orders utilizing at least two different diffractive powers.
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 diffractive achromat configured to direct light to a common focus, with individual zones of the diffractive achromat directing light to the common focus in at least two different diffractive orders utilizing at least two different diffractive powers;
- and
- a manufacturing assembly that fabricates the optic based on the profile.
