Artificial corneas could restore sight to millions

From a report at the link below:

An experimental synthetic cornea implanted in 10 patients may be a potential alternative to cadaver corneas for curing vision loss caused by corneal inflammation and scarring.

Eye surgeons primarily use cadaver corneas for transplants, but that requires the use of anti-rejection drugs and presents a risk of infection.

There is also a shortage of donated corneas in much of the world.

Plastic corneas can be used, but they present other problems and are generally tried only when tissue transplants have failed.
