Abstract
An intraocular lens system including one or more intraocular lenses (IOL) and a peripheral holder. The peripheral holder is configured to receive and retain the distal end of a fixation member of the IOL and provide a dynamic interface between the natural capsular bag and fixation member. The holder is preferably annular and flexible and transmits movement of the capsular bag from the surrounding ciliary muscles to the IOL. In this manner, a circumferential surface contact with the capsular bag is provided and accommodation of the IOL is improved. If two IOLs are received in the holder, a spacer may be provided to insure consistent spacing between the IOLs. Alternatively, an IOL system may include two IOLs and a spacer, without the holder. The holder desirably includes a sharp exterior corner to inhibit cell growth and posterior capsular opacification.
