An intraocular lens system includes an active lens element (301E) to provide dynamic optical power for active accommodation. The active lens element has mechanical indentations (307) disposed along a perimeter of the active lens element and the mechanical indentations form structurally weakened locations in the active lens element. A first pair of the mechanical indentations defines terminal ends of a first folding line (309) extending between the first pair of the mechanical indentations, and the first pair of the mechanical indentations promotes folding of the active lens element along the first folding line. The IOL system also includes control circuitry coupled to the active lens element to control the active lens element during the active accommodation. The system can comprise a second pair of the mechanical indentations, a third pair of the mechanical indentations, and a fourth pair of the mechanical indentations, wherein the second pair of the mechanical indentations define terminal ends of a second folding line extending between the second pair of the mechanical indentations, wherein the second pair of the mechanical indentations promote folding of the active lens element along the second folding line, and wherein the first folding line and the second folding line promote folding of the active lens element into three sections, wherein the third pair of the mechanical indentations and the fourth pair of the mechanical indentations are disposed to provide symmetry of mechanical indentations.Cette invention concerne un système de lentille intraoculaire comprenant un élément de lentille actif (301E) capable de fournir une puissance optique dynamique pour une accommodation active.
