Abstract: 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.
