The present disclosure concerns a curvature-changing, accommodative intraocular lens (IOL) that may be implanted in the capsular bag of a patients eye and is configured to harness the energy of the movement of the capsular bag upon contraction and relaxation of the ciliary muscles. In certain embodiments, the IOL includes a fluid optic body defining a cavity for containing an optical fluid, the cavity at least partially defined by a first optical membrane configured to extend across an optical axis of the patients eye. The IOL further includes a plurality of lever arms extending from the optic body and configured to be in contact with the capsular bag such that axial compression of the capsular bag causes each of the plurality of lever arms to rotate about a corresponding pivot so as to modify a curvature of the first optical membrane. 本披露涉及种改变曲率型可调节眼内晶状体(IOL)，该眼内晶状体可以植入患者眼睛的囊袋中并且被配置成在睫状肌收缩和放松时利用该囊袋的移动能量。在某些实施例中，该IOL包括流体光学本体，该流体光学本体限定了用于容纳光学流体的空腔，该空腔至少部分地由被配置成延伸跨过患者眼睛的光轴的第光学膜限定。该IOL进步包括多个杠杆臂，这些杠杆臂从该光学本体延伸并且被配
