    • 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.
    • 本公开涉及可以植入患者眼睛的囊袋中的曲率改变的调节性眼内透镜(IOL),并且被构造成在睫状肌收缩和松弛时利用囊袋的移动能量。 在某些实施例中,IOL包括限定用于容纳光学流体的空腔的流体光学主体,所述空腔至少部分地由配置成延伸穿过患者眼睛的光轴的第一光学膜限定。 IOL还包括多个杠杆臂,其从光学主体延伸并被构造成与囊袋接触,使得囊袋的轴向压缩使得多个杠杆臂中的每一个绕相应的枢轴旋转,以便修改 第一光学膜的曲率。
