摘要： Aspheric optical lenses (e.g., intraocular lenses and contact lenses) are provided. The intraocular lens includes a body portion defining an anterior optical surface and an opposing posterior optical surface. The anterior optical surface includes a central region surrounded by a first outer region and a second outer region. The central region has a first asphericity profile. The first outer region has a second asphericity profile that is different than the first asphericity profile of the central region. The second outer region has a third asphericity profile that is different than the second asphericity profile of the first outer region. The overall asphericity profile of the optical lens provides different depths of focus for different pupil sizes. The result is an optical lens that provides increased depth of focus or pseudo-accommodation while maintaining desired optical power and performance.

摘要： 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.
