  • CURVATURE CHANGING ACCOMMODATIVE INTRAOCULAR LENS
    Publication number: 20140180405
    Abstract: A curvature changing accommodative intraocular lens is provided in which the anterior surface of the intraocular lens undergoes dynamic change in curvature to focus light from distant objects to those nearby. The lens utilizes fluid movement from bladders defined as junctions between haptic elements and lens element or bladders positioned between the haptic elements and lens element periphery to change the curvature.
