Abstract
A supplemental intraocular lens is provided for either preoperative or postoperative attachment to a conventional implanted intraocular lens to provide an adjustable or removable multi-focal optic or to provide a necessary optic of spherical, cylindrical or combination shape for refractive error correction in aphakic patients. An intraocular lens system is also provided including a primary intraocular lens modified to provide for securing a supplemental corrective intraocular lens to the primary lens. Either the primary or supplemental lens could be formed of a suitable multi-focal lens, or both lenses could be mono-focal.
