摘要：
An intraocular lens for providing a subject with vision at various distances includes an optic having a first surface with a first shape, an opposing second surface with a second shape, a multifocal refractive profile, and one or more diffractive portions. The optic may include at least one multifocal diffractive profile. In some embodiments, multifocal diffractive and the multifocal refractive profiles are disposed on different, distinct, or non-overlapping portions or apertures of the optic. Alternatively, portions of the multifocal diffractive profiles and the multifocal refractive profiles may overlap within a common aperture or zone of the optic.
