An exchangeable intraocular lens device having a flexible, high-memory expansile lens fixation platform adapted to receive the haptics of an intraocular lens, and their method of use, are provided. The device is specifically designed to expand completely into the equatorial fornix of the capsular bag and become permanently implanted therein. The design of the present invention addresses the desire of patients to exchange their existing intraocular lens to meet their changing visual needs or to take advantage of improved lens technology, without incurring the significant risks typically associated with exchange of current intraocular lens technology. The exchangeable intraocular lens device provides accurate centration, positioning, and stability of the intraocular lens in the capsular bag. The exchangeable intraocular lens device reduces lens epithelial cell migration and resultant posterior capsule opacification.
