PROBLEM TO BE SOLVED: To reduce the contact area of an intraocular lens with the crystalline lens when it is intraocularly implanted. SOLUTION: An intermediate portion 2 is provided in the periphery of an optical lens 1, and four fin-shaped supporting portions 3 are annexed to the periphery of the intermediate portion, and made foldable by a transparent synthetic resin material. The optical lens 1 is formed so as to have refractive power, and four through holes 2a as conduits for improving the flow of the aqueous humor, and a plurality of circular recesses 2b for reducing the contact area of the lens with the crystalline lens in the eye are formed on the side facing the crystalline lens as if to surround the optical lens 1 in the intermediate portion 2 when it is intraocularly implanted.
