A curvature changing accommodative intraocular lens for implantation into the eye of a patient includes a lens body having a base lens which has a base lens power, and a haptic structure including haptic elements projecting from the base lens. An actuator is placed into engagement with the lens body, and includes actuator haptic elements. At least one fluidic optical element is received between the actuator and base lens of the lens body and contains a fluid material therein. During accommodation of the patient's eye, the haptic elements of the lens body and actuator are engaged and apply a force to the fluidic optical element, causing the fluidic optical element to be deformed to generate an additional lens power to adjust the patient's vision.
