...herpesvirus-can also attack the surface of the eye; if unchecked, it can do damage that will scar the cornea, resulting in partial or complete blindness. The best treatment has hitherto proved successful in only 60% of cases, and the disease ranks as the commonest infection causing corneal scarring. Faced with cases that seemed beyond help, Dr. Bellows decided to try a cryoprobe chilled to a temperature...
...basement when pumps failed, finally reached a level of H in. Police, firemen and volunteers rushed dry ice to hospitals to keep stored blood from spoiling, sent generators to those that needed them, rigged electrical heart-pacer machines to auxiliary power, and hand-pumped iron lungs. A delicate corneal transplant, a five-hour craniotomy, and a caesarean section were performed under light from makeshift sources; five dozen babies were delivered...
Less than Graceful. Credit for the change goes mostly to such improvements as the corneal lens, made of Plexiglas, which is lighter and simpler to fit than the old soleral variety, covers only the iris and the pupil rather than the whole eye. 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...
...bulletin, which is being posted throughout the University and distributed by the Health Services, warns that wearing lenses is "not without some risk of injury." People wearing lenses more than eight to ten hours per day "eventually get into trouble with corneal abrasions," according to the bulletin. Wetting lenses with saliva may lead to infection and "should never be practiced...
