Abstract
An intraocular lens (IOL) device comprising a first lens, a second lens and a circumferential haptic. The first lens comprises a pair of opposing and deformable surfaces and a cavity defined therebetween. The first lens has a first lens diameter. The second lens has a second lens diameter. The circumferential haptic has an outer peripheral edge and couples the first lens and the second lens. A main IOL cavity is defined by the circumferential haptic, the first lens and the second lens. The IOL device is resiliently biased to an unaccommodated state, characterized by the IOL device having a first diameter d1 in the absence of radial compressive forces exerted on the outer peripheral edge. The IOL device actuates to an accommodated state being characterized by a second diameter d2 in response to radial compressive forces exerted on the outer peripheral edge, wherein d1>d2.
