...boom in operations to change corneal curvature...
...change the curvature of the cornea so the images fall directly on the retina. The pioneer of surgery that accomplishes that optical feat is Ophthalmologist José Barraquer of Bogotá, Colombia, who for the past two decades has been performing a variety of delicate and complex corneal operations that he calls refractive keratoplasty (an operation on the cornea for optical reasons). In one procedure known as keratomileusis (cornea carving), the front of the cornea is sliced off with a high-speed vibrating blade, quickly frozen, and then reshaped on its underside by a lathe set by computer calculations. After...
...deceive his colleagues into believing that he had grafted black skin onto white animals. He also insists that his reports of successfully transplanting cultured human corneas into rabbits were not deliberately misleading. Instead, Summerlin says, they were based on the erroneous assumption that animals that had actually received a corneal implant in only one eye had been given new corneas in both. Says he: "No one wishes more than I that the actual facts regarding the rabbits had been communicated...
Summerlin may not have known that the ophthalmologists who worked with him on the corneal transplants had revised the protocols for the study. But his explanation of the mouse painting, which he says he tried to discuss with Good that same day, makes little sense. Other aspects of Summerlin's defense seem frail indeed. It is difficult to support Summerlin's suspicion that Good, who had been his mentor at the University of Minnesota, turned on him and attempted to force him out of S.K.I.; as director of the institute, Good could have got rid of Summerlin without...
...unrelated one, implanted human corneas in rabbits, and transplanted adrenal and parathyroid glands from animal to animal. But after appearing before the committee for a total of eight hours, Summerlin-in addition to admitting that he had used a pen to touch up the mice-conceded that no successful corneal grafts had occurred. The committee found that the results of his gland transplants were at best equivocal...
