An intraocular lens ( 30 ) having focusing capabilities permitting focusing movement of the lens ( 30 ) in response to normal ciliary body ( 24 ) movement incident to changes in the distance between the eye and an object under observation is provided. The lens ( 30 ) is designed for surgical implantation within the capsule ( 20 ) of an eye ( 10 ) and includes an optic ( 32 ) and an optic positioning element ( 33 ) which cooperate to form the lens ( 30 ). Accommodation is achieved by relying upon the thickening and thinning of the optic ( 32 ) as a result of the normal retracting and contracting of the ciliary body ( 24 ) in response to the distance of an object from the viewer.
