The lens of the eye sometimes becomes opaque (cataract formation), apparently due to cross-linking of its proteinaceous material, and must be removed to restore vision. Intraocular lens implants are normally made from poly(methyl methacrylate), although other materials. Including hydrogels, have been tried. In over 73% of the cases, vision of 20/40 or better can be achieved by these implants (67). The cornea is also subject to cataract formation and...
