A two or three component intraocular lens system. The first component (12) is a ring-like supporting component that is implanted in the capsular bag following cataract surgery. The first component (12) is a non-optical component that does not correct for any refractive errors, and it may contain features to help reduce or eliminate posterior capsule opacification (PCO). The second component (14) is an optical component that may contain all of the corrective optical power of the lens system. It has a pair of haptics (24) for locking the second component (14) within the first component (12). The third component (16) is similar to the second component (14) and may be used to correct for any residual optical error not corrected by the second component (14). The second and third components may also be implanted so as to move relative to one another, thereby providing some accommodation.
