摘要:
An improved multifocal design for IOL is provided. A particular embodiment includes an intraocular lens (IOL) with a foldable optic. The IOL also includes multi-hinged haptics coupled to the foldable optic operable to position the IOL within an eye. Each of the multi-hinged haptics includes a first hinge and a second hinge farther from the foldable optic. The first hinge has a first thickness between an anterior side and a posterior side of the multi-hinged haptic, the second hinge has a second thickness between the anterior side and the posterior side of the multi-hinged haptic, and the first thickness is greater than the second thickness. Another embodiment of the present invention provides a method to correct the visual impairment of an aphakic patient by implanting such an IOL.
