Lenses having diffractive profiles with irregular width for vision treatment

Abstract

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for providing improved extended depth of focus lenses. Exemplary ophthalmic lenses can include an optic including a diffractive profile including a plurality of echelettes, each echelette of the diffractive profile having a different width in r-squared space than any other echelette of the diffractive profile and each echelette of the diffractive profile being configured to distribute light to a distance focus.

Dependencies are inferred from the claim text.
