PROBLEM TO BE SOLVED: To provide an intraocular lens member and an intraocular lens that allow the eye to exhibit the accommodation ability based on a change in shape of the lens capsule due to tension and relaxation of the ciliary muscle and a change in tensile force acting on the lens capsule, and that allow achievement of normal vision and aberration correction.SOLUTION: An intraocular lens member is accommodated in the lens capsule and freely deformed according to deformation of the lens capsule. The intraocular lens member has a hallow part. When an outermost surface in the intraocular lens member is taken as an outer plane and a plane to form the hollow part in the intraocular lens member is taken as an inner plane, a curvature radius of the outer plane is different from that of the inner plane in at least one of an anterior capsule portion and a posterior capsule portion at the center of the intraocular lens member in a plane view.COPYRIGHT: (C)2014,JPO&INPIT【課題】毛様体筋の緊張および弛緩による水晶体嚢の形状の変化ないし水晶体嚢に作用する張力の変化に基づく眼の調節力を発揮させることを可能としつつ、正視化及び収差補正を達成し得る眼内レンズ用部材及び眼内レンズを提供する。【解決手段】水晶体嚢内に収められ、水晶体嚢の変形に伴って変形自在となり得る眼内レンズ用部材であって、前記眼内レンズ用部材は中空部を有し、前記眼内レンズ用部材における最表面を外面、前記眼内レンズ用部材において前記中空部を形成する面を内面とすると、前記眼内レンズ用部材を平面視した際の中央部において、前嚢側の部分及び後嚢側の部分の少なくとも一方では、前記外面の曲率半径と前記内面の曲率半径とが互いに異なる。【選択図】図1
