[quote]Ocular prostheses - Products such as contact lenses and
intraocular lenses have been successfully modified by plasma treatment
to impart protein- and cell-repelling characteristics, decrease
bacterial adhesion, improve wettability and enhance patient comfort.
Also, an ammonia plasma treatment has been applied to artificial
corneas to enhance corneal epithelial cell attachment and growth.[/

I wear a plasma treated 'scleral' lens (made from the same material as
a Boston RGP lens).   I don't have much to compare it to, but it seems
to work quite well.
