    Abstract: An implantable ophthalmic device with flexible, fluid-filled membranes provide dynamically variable optical power to restore lost accommodation in individuals suffering from presbyopia or aphakia without moving parts or reducing the amount of transmitted light. Actuating the device causes the fluid-filled membrane to change curvature, which produces a corresponding change in optical power. For instance, squeezing the edge of the membrane causes the center of the membrane to bulge by an amount proportional to the squeezing force. Alternatively, heating or applying a voltage to the membrane may cause the liquid in the membrane to undergo a phase transition accompanied by a corresponding change in volume that causes the membrane to inflate so as to change the optical power of the device.

    Abstract: An implantable ophthalmic device with one or more optical elements coupled to one or more shape-memory members provides dynamically variable optical power to restore lost accommodation in individuals suffering from presbyopia or aphakia. Running current from a power supply through the shape-memory members causes the shape-memory members to heat up. Once the current heats the shape-memory members past a forward phase-transition temperature, the shape-memory members change shape, which, in turn, causes the optical element(s) to move, yielding a corresponding change in effective optical power. Cooling the shape-memory members (e.g., by reducing or stopping the flow of current) below a reverse phase-transition temperature causes the shape-memory members to return to their original shape, which, in turn, restoring the optical element(s) to their original positions and returning the effective optical power to its original level.

    Abstract translation: 具有柔性流体填充膜的可植入眼科装置提供动态可变的光学功率，以恢复患有老花眼或无晶状体的个体的失去的适应性，而无需移动部件或减少透射光量。 驱动该装置导致流体填充的膜改变曲率，这产生相应的光功率变化。 例如，挤压膜的边缘导致膜的中心膨胀与挤压力成比例的量。 或者，加热或向膜施加电压可能导致膜中的液体经历伴随相应的体积变化的相变，导致膜膨胀以改变装置的光功率。
