  • Dual optic, curvature changing accommodative IOL having a fixed disaccommodated refractive state
    Patent number: 9931202
    Abstract: An IOL includes a fluid optic body having a cavity defined by a sidewall, a deformable optical membrane intersecting the sidewall around an anterior circumference of the sidewall, and a posterior optic intersecting the sidewall around a posterior circumference of the sidewall. The posterior optic includes a central protrusion extending anteriorly into the cavity and the deformable optical membrane includes a ring-shaped protrusion extending posteriorly into a space between the sidewall and the central protrusion. A second optic body is spaced apart from the fluid optic body and coupled thereto via a plurality of struts. Axial compression causes the plurality of struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane is modified. Contact between the ring-shaped protrusion and the central protrusion defines a maximum modification to the curvature of the deformable optical membrane.
