Attempts to change the way the cornea focuses light by surgically altering its surface began as early as the 1950s. By the 1970s Soviet doctors routinely used scalpels to reshape the corneas of nearsighted patients in an operation called radial keratotomy. But the surgery, involving a spokelike ring of incisions, never really caught on in the U.S., because the results were so difficult to predict and the healing process was often slow and painful...
...cornea's outermost protective layer, or epithelium. Then they vaporized some of the underlying tissue with the laser, forcing the cornea to flatten or steepen, depending on the correction. Although the epithelium always grew back, the cornea retained its new shape. It was a big improvement over radial keratotomy, although the healing of the epithelium remained painful...
...does not reflect quality improvements adequately. If radial tires last three to five times longer than the bias-ply tires they replaced, their price could go up in dollars but drop per mile driven. But the CPI reflects this only partly...
...University of Southern Mississippi in Hattiesburg, where he openly advertised his admiration for Martin Luther King and led civil rights teach-ins. He questioned how much some of the students were learning, though, when one counterdemonstrator scrawled a note on his door, GO BACK TO MOSCOW, YOU BIG RADIAL! [sic]. Uncertain about whether he wanted to continue teaching, Bennett in 1969 enrolled in Harvard Law School, meanwhile working as a dorm proctor and tutor. John Carnutte, now an immunologist in California, recalls arriving at Harvard from Dixon, Illinois, accompanied by his mother. "There were marijuana clouds over Harvard Square...
...People who turn to surgery to correct their nearsightedness may not escape having to wear glasses after all. A 10-year study shows that a third of patients who undergo radial keratotomy, in which the corneas are resculpted for better vision, gradually develop farsightedness and may need reading glasses sooner than they would have without the procedure...
