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.
Claims35
An ophthalmic lens comprising:
- 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.
A method comprising:
- fabricating an optic for an ophthalmic lens, the optic being 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.
A system for fabricating an ophthalmic lens, the system comprising:
- a processor configured to determine a refractive profile of an optic, the 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;
- and
- a manufacturing assembly that fabricates the optic based on the refractive profile.
