Abstract
An intraocular lens arrangement having positive or negative lens with a frame that extends from the lens to provide diametrically opposed upper and lower frame sections. A first lens linkage has its first end attached to the upper frame section with at least two points of contact with the upper frame section. A second lens linkage has its first end attached to the lower frame section with at least two points of contact with the lower frame section. A second end of said first lens linkage and a second end of the second lens linkage are attached to a sulcus or zonule member to provide relatively large movement of the lens with a small movement of the ciliary muscle during accomodation response of the eye, and wherein the movements during the accommodation response are along the optical axis of the eye and are controlled in order to improve the image on the retina of objects viewed by the eye over a wide range of distances. The lens is preferably a positive lens with the appropriate frame. The haptics that connect the frame to the sulcus member is at least two pairs of haptics or alternatively a pair of single curved haptics that each have a sulcus connecting member. The intraocular l…
