An adjustable multifocal intraocular lens system for an individuals eye, includes a base multifocal intraocular lens having an optic with an optical axis, a peripheral edge, a multifocal optical power anterior surface and a posterior surface along with an attachment for maintaining the base multifocal lens in the individuals eye with the optical axis centered along an eye optical axis. An enhanced multifocal intraocular lens is provided with an optic with a peripheral edge, an anterior surface and a reverse multifocal optical power posterior surface, and a coupling enables assembly of the base lens and enhance lens with the enhance lens posterior surface overlaying the base lens anterior surface in order that the enhance intraocular lens reverse multifocal surface adjust multifocal powers of the base IOL by substantially masking near power of the base multifocal intraocular lens.
