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 at least one set of echelettes, each echelette of the set having a different width in r-squared space than any other echelette of the set and the at least one set of echelettes repeating at least once upon the optic.

Abstract: Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for vertex matching distance regions of such lenses. Exemplary ophthalmic lenses can include an optic disposed about an optical axis and having a refractive profile including a region having an add power and a first distance region and a second distance region extending outward from the first distance region and being vertex matched with the first distance region.

Abstract: Apparatuses, systems, and methods for providing improved intraocular lenses (IOLs) and other refractive treatment modalities involve fabricating the IOL or developing the treatment based on a refractive profile. Exemplary techniques include obtaining a base wavefront power profile corresponding to a theoretical lens, adding a second wavefront profile defined by the combination of one or more zones described by a cosine function to obtain a final wavefront power profile, determining a refractive profile based on the final wavefront power profile, and fabricating the intraocular lens or determining the treatment based on the refractive profile.
