Researchers are adapting other materials, notably a hydrophilic plastic: invented by two Czech scientists, the new rubbery lens is so flexible it never irritates the eye, and is porous enough to be worn while asleep...
Screw-In Cornea. Ironically, the earliest attempt to use a primitive plastic involved one of the most intricate organs in the body. It was an 1853 attempt to replace the cornea of the eye, and it failed. Then the technique of human corneal transplants was developed, and the urgency of finding a plastic seemed to diminish. But human transplants do not stay clear in all cases. An imaginative ophthalmic surgeon, Dr. William Stone Jr., working first in Boston, then in Los Angeles, has devised a corrective corneal implant of plastic...

They agreed to donate their corneas to the Eye Bank of Pittsburgh...
