An intraocular lens arrangement having positive 4 and negative 5 lens elements which move during the eye's accommodation response in order to improve the image on the retina 3 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 be 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.
