Abstract:
A multifocal intraocular lens for providing vision correction power, the multifocal intraocular lens having a central optical axis, an outer periphery and a baseline diopter power for far vision correction, the multifocal intraocular lens being sized and structured to be implanted in an eye, and comprising:a central zone having a vision correction power at the central optical axis no less than the baseline diopter power and a vision correction power approximately equal to or greater than the baseline diopter power, the central zone having a progressive power region in which the vision correction power varies progressively; a first zone having a near vision correction power, the first zone being located radially outwardly of the central zone; and a second zone located radially outwardly of the first zone and extending to the outer periphery of the multifocal intraocular lens and having a vision correction power less than the baseline diopter power substantially throughout the second zone.
