Abstract
The present invention describes a refractive multifocal intraocular lens with aspheric geometry on both surfaces in such a way that the map of local optical strength of the lens, combined with the cornea, has a central region of intermediate optical strength surrounded by a ring of maximum optical strength, with a smooth transition between the two, after which it alternates smoothly between rings of varying strengths.
