Abstract
A surface treated intraocular lens implant for use in the replacement of a cataracts natural lens to prevent posterior cellular opacification. The surface treated intraocular lens includes one or more carbohydrates covalently bound to the surface of the intraocular lens implant and a carbohydrate binding agent conjugated to a cytotoxic agent for binding said carbohydrates. The cytotoxic agent present on the intraocular lens implant serves to destroy residual lens epithelial cells within the lens capsule thereby preventing posterior cellular opacification of the intraocular lens implant.
