Multifocal intraocular lens

An ophthalmic lens, comprising:

• an optic comprising a first surface having a first shape and an opposing second surface having a second shape, the shapes together providing a base optic power;
• an inner zone disposed about an optical axis, an intermediate zone disposed about the inner zone, and an outer zone disposed about the intermediate zone;
• a first diffractive profile imposed on one of the shapes and radially disposed within the inner zone;
• a second diffractive profile imposed on one of the shapes and radially disposed within the outer zone;
• a multifocal refractive profile imposed on one of the shapes and including a refractive portion radially disposed within the intermediate zone between the first diffractive profile and the second diffractive profile, the multifocal refractive profile including a refractive add portion having refractive add power;
• wherein at least one of the diffractive profiles is a multifocal diffractive profile having, for visible light, a primary diffraction order, a secondary diffraction order, and a diffractive add power corresponding to a difference in optical power between the secondary diffraction order and the primary diffraction order;
• and
• wherein the multifocal refractive profile is imposed on the first shape of the first surface of the optic and the multifocal diffractive profile is imposed on the second shape of the opposing second surface of the optic.
