<p>A two- or three-component lens intraocular system (10) is provided. The first component is a ring-like supporting component (12, 12', 12") that is implanted in the capsular bag of the eye following cataract surgery. The first component is a non-optical component that does not correct for any refractive errors, and may contain features that help to reduce or eliminate PCO. The second component (14) is an optical component (15) that may contain all of the corrective optical power of the lens system. The second component has a pair of tabs (24) for locking the second component within the first component. The first component has a feature (150,201-203) that allows the surgeon to change the position of the second component along the optical axis (28) of the system. The third component (16) is optional and is similar to the second component and contains some optical power to correct any residual optical error not corrected by the second component. The second and third components may also be implanted so as to move relative to one another, thereby providing some accommodation.</p> |
