摘要： An intra ocular lens arrangement having positive and negative lens elements which move during the eye's accommodation response in order to improve the image on the retina of objects viewed by the eye over a wide range of distances. The positive and negative lens elements either can be linked mechanically to constrain their relative movements or not linked. The lenses are positioned by an operating surgeon following cataract extraction in either the eye's ciliary sulcus or lens capsule. Alternatively, one of the lenses may be inserted into an eye that already has a lens implanted therein to further improve a person's vision. An improved intra ocular lens has is an optic lens having at least two pairs of haptics that controls the movement of the optic lens along the optical axis of the eye in response to the movement of the ciliary muscle of the eye acting on the haptics during the accommodation response, one pair of haptics having one end hinged to the lower half of the optic lens and the second end connected to an upper portion of the ciliary muscle, and a second pair of haptics hinged to an upper half of the optic lens and to a lower potion of the ciliary muscle.
