ABSTRACT:
Epithelial-cell and protein-strand development, following eye surgery such as an intracapsulary lens extraction and intraocular-lens implantation, is retarded or impeded by providing small amounts of metal and/or basic salt in the environment or in the construction of an intraocular lens. It is believed that the use of one or more metals or a basic salt will provide an electrolytic action within the capsule and that cell growth and motility are thereby materially reduced. The electrolytic action is accompanied by an associated change in the oxygen availability that would otherwise have aided cell regrowth. Stated in other words, the changed Ph, temperature and chemical balance that result from a metal or basic-salt presence within the capsule reduces or eliminates the ability of epithelial cells to multiply.
