MULTIFOCAL ACCOMMODATING INTRAOCULAR LENS |
摘要 |
An intraocular lens for providing accommodative vision includes an adjustable optic and a haptic that is operably coupled to the optic. The adjustable optic comprises a central zone and an annular zone surrounding the central zone. The optic may also comprise additional annular zones. 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. 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.
