A lens implant serves to replace the lens body of an eye and possesses substantially the same size and shape. It is elastic such that the eye gets back its capability for accommodation. The lens implant has two parts with differing refractive indices and/or differing shapes, which allows to adapt the focal length and shape to specific requirements in simple manner. A distal part is prefabricated as pre-made lens part, while a proximal part can preferably be brought into the lens capsule in a flowable state.
