The present disclosure concerns a curvature-changing, accommodative intraocular lens (IOL) for implantation in the capsular bag of a patient’s eye. The IOL includes a fluid optic body having a cavity for containing an optical fluid, the cavity at least partially defined by a sidewall extending around the cavity and defining a diameter of the cavity and a deformable optical membrane intersecting the sidewall around a circumference of the sidewall and spanning the diameter of the cavity. The IOL further includes a second optic body spaced a distance apart from the fluid optic body and a plurality of struts extending from the sidewall and coupling the fluid optic body to the second optic body. The struts are configured such that axial compression of the capsular bag causes the struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane.本揭示案係關於用於植入患者眼睛之囊袋中的曲率變化、調節式眼內透鏡(IOL)。該IOL包括具有用於含有光學流體之空腔的流體鏡片主體,該空腔至少部分地由以下者界定:側壁,該側壁圍繞該空腔延伸且界定該空腔之直徑;以及可變形光學膜,該可變形光學膜圍繞該側壁之圓周相交於該側壁且跨越該空腔之該直徑。該IOL進一步包括:第二鏡片主體,該第二鏡片主體與該流體鏡片主體間隔一距離;以及複數個支柱,該等支柱自側壁延伸且將該流體鏡片主體耦接至該第二鏡片主體。該等支柱經組配以使得該囊袋之軸向壓縮致使該等支柱以增加該空腔之該直徑的方式使該側壁變形,以變更該可變形光學膜之曲率。
