PROBLEM TO BE SOLVED: To solve the problem in which, unless a support part is formed in a diagonally warp manner with respect to an optical part, contraction of a crystalline capsule may cause an intraocular lens to come into contact with an iris.SOLUTION: An intraocular lens includes an optical part having two optical surfaces, and a support part for supporting the optical part, and is used so as to be stored in a crystalline capsule of an eyeball. The support part has a flexible part 25 which is arranged so that, when it is disposed in the crystalline capsule, it faces an equatorial part of the crystalline capsule, and is elastically deformed by receiving inward force due to contraction of the crystalline capsule. In a rear side Rs of an outside surface 26 of the flexible part 25 in contact with the equatorial part within the crystalline capsule, formed is an inclined surface 31 inclined along a shape on a rear capsule side of the crystalline capsule.【課題】光学部に対して支持部を斜めに反らせて形成しないと、水晶体嚢の収縮によって眼内レンズが虹彩に接触するおそれがあった。【解決手段】二つの光学面を有する光学部と、これを支持する支持部とを備え、眼球の水晶体嚢内に収めて使用される眼内レンズである。支持部は、水晶体嚢内に挿入されたときにその赤道部に対向するように配置され、水晶体嚢の収縮による内向きの力を受けて弾性変形する可撓部25を有し、水晶体嚢内で赤道部に接する可撓部25の外側面26の後ろ側Rsに、水晶体嚢の後嚢側の形状に沿うように傾斜した傾斜面31が形成されている。【選択図】図3
