An intraocular lens (IOL) has a small, central lens suspended within a pliable housing and, when the housing is filled with liquid, is coaxially aligned with a second small lens embedded in the wall of the housing. The suspension is on a dome- or other-shaped webbing attached to an inner circumference of the wall. When filled with liquid, forces squeezing or pulling the equator of the housing, as with ciliary muscles in the eye, adjust a distance between the lenses in order to adjust focus. Optional haptics may project from points on or above and below the equator. A recess in the posterior hemisphere of the housing can keep cell growth away from an optical axis of the lens system. A third small lens can be embedded in an opposite wall of the housing and coaxially aligned with the other lenses to form a three-lens, ultra-zoom system.
