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.
Claims10
An intraocular lens (IOL) comprising:
- an optic disposed about an optical axis and having a refractive profile including a region having an add power and a first distance vision region and a second distance vision region extending outward from the first distance vision region and being vertex matched with the first distance vision region,
- wherein the first distance vision region is a central region of the optic that the optical axis extends through,
- wherein the region having the add power is a near vision region positioned between the first distance vision region and the second distance vision region,
- wherein the near vision region is adjacent both the first distance vision region and the second distance vision region,
- wherein the second distance vision region extends outward from the near vision region, and has its vertex shifted by the presence of the near vision region,
- wherein the second distance vision has a lesser power than the first distance vision region,
- wherein the first distance vision region, the near vision region, and the second distance vision region form annular regions around the optical axis of the optic.
