The AIOL assemblages include an AIOL capsule and an integrally formed base member. The AIOL assemblages also include an annular haptics support surround posterior to an anterior structure on implantation in a human eye of a supine human. AIOL assemblies are assembled in situ by mounting a haptics system onto a previously implanted AIOL assemblage. The haptics system bears against the annular haptics support surround.

Accommodating intraocular lens
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.

Accommodating intra-ocular lens system
An implantable, compressible, accommodating intra-ocular lens (IOL) coupled to at least one sensor which detects a signal created by the ciliary muscle. A ciliary sulcus ring can house the at least one sensor, and the sensor can include miniaturized electrodes (ciliary muscle probes) for implanting into the ciliary muscle of the subject. A potentiometer / microcomputer can modulate the ciliary muscle signal detected by the sensor(s) into an electrical signal, and a transmitter sends this electrical signal to a micromotor, which causes compression of the IOL via an annular support ring system, causing a change in the IOL shape. The IOL can be part of an IOL complex including a compressible, accommodating IOL, an external lens membrane, and an annular support ring system. The annular support ring system provides a foundation for the micromotor to compress the IOL.
