Abstract: An intra-ocular lens having an air-filled collapsible cavity situated between two optical elements wherein air is transferred from optical regions of the collapsible cavity to its peripheral haptic regions after being compressed by external force.

Abstract: The invention provides for an inflatable intra ocular lens/lens retainer or a system of inflatable intra ocular lens/lens retainers, which are fitted into an aphakic eye, to substantially occupy the space previously held by the crystalline lens to retain and secure the position of delicate intra ocular structures of the eye. The inflatable lens/lens retainer may also be used suspend optical interfaces along the visual axis of the eye. The inflatable intra ocular lens/lens retainer may be pressed against residual elements of the lens capsule to re-establish accommodation. In the absence of a lens capsule, the inflatable intra ocular lens/lens retainer may be compressed directly by the ciliary muscle to alter the refractive state of the eye.
