[Abstract] The present invention aims to provide an accommodative intraocular lens capable of sufficiently exerting focusing ability. The present accommodative intraocular lens 1 is provided with an optical section 10 of a lens, and a lens supporting section 20 provided at the peripheral portion of the optical section 10. The lens supporting section 20 includes one end portion 201 connected to the peripheral portion of the optical section 10 via the connecting portion 50 in a movable manner, and the other end portion 202 to be engaged with the equator Se of the lens capsule S. The one end portion 201 and the other end portion 202 are positioned on opposite sides across the center O of the optical section 10, and are formed in a manner as to extend on radially outward side in a loop shape surrounding the periphery of the optical section 10 from one end portion 201 to the other end portion 202. In accordance with the movements of the lens capsule S near the equator Se caused by the focusing of an eye, the other end portions 202 of the lens supporting sections 20 move in the approaching/departing direction, which moves the optical section 10 in the optical axis direction.【課題】本発明は、焦点調節力を十分に発揮することができる調節眼内レンズを提供することを目的とする。【解決手段】本調節眼内レンズ１は、レンズからなる光学部１０と、光学部１０の周縁部に設けられたレンズ支持部２０とを備える。レンズ支持部２０は光学部１０の周縁部に連結部５０を介して可動可能な状態で連結される一方端部２０１と、水晶体嚢Ｓ赤道部Ｓｅに係止される他方端部２０２とを有し、一方端部２０１と他方端部２０２が光学部１０の中心Ｏを介して互いに反対側に位置しかつ一方端部２０１から他方端部２０２にかけて光学部１０の周囲を取り囲むループ状に径方向外側で延びる態様で形成される。眼の焦点調節により発生する赤道部Ｓｅ付近における水晶体嚢Ｓの動きに応じてレンズ支持部２０の他方端部２０２同士が近接離間方向に移動することにより光学部１０が光軸方向に移動する。【選択図】図１
