Abstract
An accommodating intraocular lens apparatus preferably includes a lens member having a relatively flexible portion and a relatively rigid portion, with a fluid-filled chamber therebetween. The preferred intraocular lens also includes a hydraulic or other fluid accommodation provision for changing the shape or position of the flexible lens by changing the fluid pressure in the fluid-filled chamber in response to muscle movement of the eye.
