    • An intraocular lens for providing accommodative visions to a subject includes an adjustable optic and a haptic that is operably coupled to the optic. The adjustable optic comprises an optical axis, a central zone disposed about the optical axis, and an annular zone surrounding the central zone. The optic may also comprise additional annular zones disposed about the central zone and the first annular zone. The haptic comprises a transparent portion protruding into the adjustable optic. The intraocular lens has a disaccommodative configuration in which the central zone has a base optical power and an accommodative configuration in which the central zone has an add optical power that is at least about 1 Diopter greater than the base optical power, preferably at least about 2 Diopters greater than the base optical power. In some embodiments, the add optical power is at least 3 Diopters, or even 4 Diopters, greater than the base optical power. The central zone and the annular zone have different optical powers when the adjustable intraocular lens is in the accommodative configuration and/or when the adjustable intraocular lens is in the disaccommodative configuration.
    • 用于向受试者提供调节视力的眼内透镜包括可操作地连接到光学元件的可调光学元件和触觉件。 可调节光学元件包括光轴,围绕光轴设置的中心区域和围绕中心区域的环形区域。 光学元件还可以包括围绕中心区域和第一环形区域设置的附加环形区域。 触觉包括突出到可调节光学元件中的透明部分。 眼内透镜具有不利的配置,其中中心区域具有基本光焦度和调节结构,其中中心区域具有比基本光功率大至少约1屈光度的添加光焦度,优选至少约2 屈光度大于基础光功率。 在一些实施例中,添加光功率大于基本光功率的至少3屈光度,或甚至4屈光度。 当可调节眼内透镜处于调节构型时和/或当可调节眼内透镜处于不利配置时,中心区域和环形区域具有不同的光焦度。
