Abstract
An artificial intraocular lens device with light-induced zoom-in and zoom-out properties includes a lens, an inert lens frame surrounding the lens; and two inert supporting arms formed at the side edge of the lens frame. The lens is made from azobenzene gel, the deformation of the azobenzene gel by expansion or contraction respectively reverses on exposure to visible light and to ultraviolet light. The azobenzene gel is formed by heating an azobenzene gel precursor for polymerization, the azobenzene gel precursor being composed of monomer, initiator, crosslinker, and azobenzene.
