Abstract
A multifocal intraocular lens (MF-IOL) includes a circularly birefringent material with a right-handed index of refraction nfor a light with a right-handed polarization, and a left-handed index of refraction nfor a light with a left-handed polarization; and haptics, to position the multifocal intraocular lens inside a capsule of an eye; wherein the multifocal intraocular lens has a right-handed optical power Dfor the light with the right-handed polarization, and a left-handed optical power Dfor the light with the left-handed polarization, wherein D/D=(n−1)/(n−1). Some variations of the MF-IOL include stimulus-orientable optically anisotropic constituents. Some classes of the MF-IOL include a self-assembling optically anisotropic compound. A corresponding method of making a MF-IOL is comprising providing stimulus-orientable optically anisotropic constituents as part of an intraocular lens; orienting the optically anisotropic constituents by applying a non-stretching stimulus; and locking-in the oriented optically anisotropic constituents to form the multifocal intraocular lens.
