ABSTRACT:
The present invention is generally directed to accommodative intraocular lenses (IOLs) that exhibit a dynamic spherical aberration as a function of accommodative power. By way of example, in one aspect, the present invention provides an intraocular lens (IOL) having an anterior optical element, a posterior optical element, and a mechanism for coupling the anterior and posterior elements so as to allow axial movement of those elements relative to one another for providing accommodation when the lens is implanted in a patient's eye. Each of the anterior and the posterior elements includes at least one aspherical surface, where the asphericities of the surfaces are adapted to provide a combined spherical aberration that varies with accommodation.
