US Patent 8066768 Intraocular lens system

A multi-component intraocular lens implanted in an optical system of a human eye includes one or more removable components, each component being foldable. One component acts as a base lens, including a flange with an aperture. Another component acts as a mid lens, including a tab which engages the aperture. A third component acts as a top lens, which engages the mid lens. Because the lens components are foldable, they may be inserted into the eye using an incision smaller than the diameter of the unfolded lens. The removable components may be used to correct various medical conditions of the eye, as well as to improve and enhance vision, and for cosmetic purposes.
