<p>A surface treated intraocular lens implant for use in the replacement of a cataract natural lens to prevent posterior cellular opacification. The surface treated intraocular lens includes one or more polysaccharides chemically bound by a difunctional cross linker and a binding agent conjugated cytotoxic agent thereon. The preferred embodiment includes heparin of chondroitin chemically coupled to the surface of the intraocular lens and polylysine conjugated Saporin, a ribosomal inhibitory protein. The cytotoxic agent present on the surface serves to destroy residual epithelial cells within the lens capsule thereby preventing secondary capsule opacification of the intraocular lens implant.</p> |
