Abstract
A surface treated intraocular lens implant for use in the replacement of a cataractous natural lens to prevent posteriror capsular opacification. The surface treated intraocular lens includes one or more proteins, polypeptides, polyamino acids or polyamines bound to the surface of the intraocular lens implant covalently, non-covalently or a combination thereof. The one or more proteins, polypeptides, polyamino acids or polyamines present on the surface of the intraocular lens implant serves to reduce or eliminate residual lens epithelial cell migration within the lens capsule. By preventing residual lens epithelial cell migration, posterior capsular opacification of the intraocular lens implant is thus reduced or eliminated.
