A system and intraocular lens system for implantation in an eye having a lens capsule and lens substance contained in the lens capsule. In one embodiment of the present invention, the intraocular lens system has a frame having a center, a first optical element with a focal power and a second optical element with a focal power. The first optical element has a center, a surface and an edge, wherein the first optical element is coupled to the frame at its edge such that the center of the first optical element is at a distance from the center of the frame. The second optical element has a center, a surface and an edge, wherein the second optical element is coupled to the frame at its edge such that the center of the second optical element is at a distance from the center of the frame. The first optical element and the second optical element at a predetermined state are positioned such that the distance between the first optical element and the center of the frame and the distance between the second optical element and the center of the frame are substantially same, and the surfaces of the first optical element and the second optical element partially overlap to form a combined lens with an effective focal power that is different from either of the focal power of the first optical element and the focal power of the second optical element.
