  • Patent number: 9468523
    Abstract: An accommodating intraocular lens (AIOL) comprising an optic, and at least one haptic plate coupled to the optic by at least one connector, the connector being less rigid than the haptic plate, the at least one haptic plate surrounding the optic, and the optic and haptic plate having a combined surface area between 70 mm2 and 100 mm2. The at least one haptic plate may form a continuous 360-degree boundary around the optic. The at least one haptic plate has a width in a radial dimension of 1.0-3.5 mm across its entire angular extent.
