An ophthalmic lens for providing a plurality of foci has an optic comprising ananterior surface, a posterior surface, and an optical axis. The optic has a firstregion and a second region. The first region has a refractive optical power andcomprises a multifocal phase plate for forming a first focus and a second focus.The second region has a refractive optical power and comprises a monofocal phaseplate for forming a third focus. The multifocal phase plate and the monofocalphase plate may be disposed on first and second base curvatures, respectively,that may have different radii of curvature. The ophthalmic lens may also havean intermediate phase plate located between the multifocal phase plate and themonofocal phase plate, the intermediate phase plate comprising a third pluralityof echelettes disposed on a third base curvature having a third radius of curvature.
