Abstract
An accommodating intraocular lens is provided, in which optical parameters are altered in-situ using forces applied by the ciliary muscles, and in which a lens body carries an actuator separating two fluid-filled chambers having either the same index of diffraction or different indices of refraction. The actuator causes the relative volumes of fluid within an optic element of the lens to change, thereby altering the optical power of the lens.
