1. A method comprising:
fabricating an optic for an intraocular lens (IOL), the optic being 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, the region having the add power, and the second distance vision region form annular regions around the optical axis of the optic,
the first distance vision region is a central region of the optic that the optical axis extends through, and
the region having the add power is a near vision region positioned between, and adjacent to, 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
determining a vertex shift of the second distance vision region caused by the near vision region, and vertex matching the first distance vision region and the second distance vision region based on the determined vertex shift, wherein the second distance vision has a lesser power than the first distance vision region.
