20130226293 | ACCOMMODATIVE IOL - REFRACTIVE INDEX CHANGE THROUGH CHANGE IN POLARIZABILITY OF A MEDIUM - In one aspect, an accommodative intraocular lens (IOL) is disclosed that includes an optic having at least a portion formed of a polarizable and/or and electro-active material. Once implanted in a subject's eye, a change in the index of refraction of the polarizable and/or electro-active portion in response to forces applied to the optic via the eye's ciliary muscle can cause a change in the optical power of the optic, thereby allowing accommodation. | 2013-08-29 |
