Abstract
An accommodating lens assembly having an optical axis and being adapted to be implanted in a posterior chamber of an eye having a capsular unit located therein. The assembly includes a rigid haptics element adapted to secure the assembly within the posterior chamber outside said capsular unit. The element is transparent at least in a region around the axis. The assembly further includes a resilient body adapted to operate as a lens having a curved surface when pressed up against the region of the haptics element by an axial force applied thereto by the capsular unit. A change in this force causes a change in a radius of curvature for the curved surface.

An accommodating lens assembly having an optical axis and being adapted to be implanted in a posterior chamber of an eye having a capsular unit located therein, the assembly comprising:
- a rigid haptics element adapted to secure said assembly within said posterior chamber outside said capsular unit, the element being transparent at least in a region around said axis;
- a resilient body adapted to operate as a lens having a curved surface when pressed up against said region of the haptics element by an axial force applied thereto by said capsular unit, whereby a change in said force causes a change in a radius of curvature for said curved surface.
An accommodating lens assembly having an optical axis and being adapted to be implanted in a posterior chamber of an eye with an optical axis having a posterior capsule, the assembly comprising:
- a rigid haptics element adapted to secure said assembly within said posterior chamber outside the capsule, the element being transparent at least in a haptics element region around said axis;
- a rigid piston member transparent at least in a piston member region around said axis and mounted in the assembly so as to be movable along said axis with respect to the haptics element, at least one of said haptics element and said piston member having a hollow space in its transparent region;
- a resilient body sandwiched between said element and said member, the body being adapted to protrude into said hollow space in the form of a bulge so as to operate as a lens with a curved surface upon the axial movement of said piston member.
