    • A mechanism allows for changing the optical strength of a liquid-filled lens having a cavity filled with fluid. A reservoir contains additional fluid and is in fluid communication with the cavity, and the mechanism draws fluid from the reservoir into the cavity or pulls fluid from the cavity back into the reservoir, whereby a change in the amount of fluid within the lens cavity changes the lens's optical strength. A membrane seals the reservoir, and a plunger impinges upon the membrane. A movement device, such as a barrel screw or lever, moves the plunger in a controlled manner toward the membrane to increase pressure within the reservoir and thereby force fluid out of the reservoir into the lens cavity, and away from the membrane to decrease pressure within the reservoir and thereby withdraw fluid from the lens cavity and into the reservoir.

    • Implantable ophthalmic devices with aspheric lenses and dynamic electro-active elements offer excellent depth of field and image quality while providing high optical throughput. An exemplary implantable ophthalmic device includes an aspheric lens with a negative spherical aberration that varies with radius. The aspheric lens can have peak optical powers at its geometric centers surrounded by a region of varying optical power (with varying slope) that extends radially from its center. When implanted, these aspheric lenses provide an incremental optical power that varies as a function of pupil diameter, which changes with object distance, for viewing far, intermediate, and near objects. The aspheric lens may also bonded or integrally formed with a spherical lens that provides fixed optical power for viewing far objects and/or a dynamic electro-active element that with two or more states (e.g., on and off) for increasing the effective optical power when viewing near objects.
    • 具有非球面透镜和动态电活性元件的可植入眼科装置提供优异的景深和图像质量,同时提供高的光学吞吐量。 示例性的可植入眼科装置包括具有随半径变化的负球面像差的非球面透镜。 非球面透镜在其几何中心处可以具有由其从其中心径向延伸的具有变化的光焦度(具有变化的斜率)的区域包围的峰值光焦度。 当植入时,这些非球面透镜提供增加的光学功率,其随瞳孔直径的变化而变化,瞳孔直径随物体距离而改变,用于观察远,中,近物体。 非球面透镜也可以与提供用于观察远物体的固定光焦度的球形透镜结合或整体形成,和/或具有两个或更多个状态(例如,接通和关断)以增加有效光功率的动态电活性元件 查看近物体时。
