摘要： An intraocular lens (1) capable of obtaining favorab7.e accommodative power, which is to be arranged inside a lens capsule as a replacement for a crystalline lens, includes a front-side and rear-side optical parts (2), (3) having predetermined refractive power and an elastic part (4) having predetermined elasticity by containing water to swell, wherein the elastic part is bonded to the optical parts so that optical axes of the optical parts coincide and so that the elastic part does not cover their optical zones, an elastic part thickness before containing water is determined so that an intraocular lens thickness after containing water completely to swell corresponds to a crystalline lens thickness at near vision, and a distance between the rear surface of the front-side optical part and the front surface of the rear-side-optical part of the intraocular lens arranged inside the lens capsule is changed according to relaxation and tension of a ciliary muscle.
