  • Patent number: 8215770
    Abstract: Embodiments of the present invention relate to an electro-active element having a dynamic aperture. The electro-active element provides increased depth of field and may be used in a non-focusing ophthalmic device that that is spaced apart from but in optical communication with an intraocular lens, a corneal inlay, a corneal onlay, a contact lens, or a spectacle lens that provide an optical power. The electro-active element provides increased depth of field and may also be used in a focusing or non-focusing device such as an intraocular optic, an intraocular lens, a corneal inlay, a corneal onlay, or a contact lens which may or may not have an optical power. By changing the diameter of dynamic aperture either increased depth of field or increased light reaching the retina may be achieved.
