  • Publication number: 20090005866
    Abstract: An accommodating lens where the optic is moveable relative to the ends of the extended haptic portions. The lens comprises an optic made from a flexible material combined with haptics capable of multiple flexions without breaking. The haptics having in longitudinal cross section wide and deep hinges adjacent the optic to better allow the elastic hinges to “stretch” when the optic is subjected to posterior pressure thus allowing the optic to move forward relative to both the outer and inner ends of the haptics. When this movement is combined with the movement of the optic relative to the outer ends of the haptics and the anterior movement of the whole lens, the refractive power of the eye is further enhanced.
