...original but still new enough to be of interest to most San Franciscans, the wholesale poultry store of Corriea Bros, was flamboyantly advertising ELECTROCUTED POULTRY. In their execution chamber a short endless belt conveyor moves alongside a longer conveyor which carries the fowl, fastened by the feet. In the Cornea store an attendant fastens the bird's head into a clamp from the short, inside belt. About a foot farther on, a lever is pressed down, completing an electrical circuit. Some 1,000 to 1,500 volts, depending on the size of the fowl, stepped up by transformers from...
...excises the cornea with a circular saw called a trephine, whose diameter is a shade more than one-sixth of an inch. He has already applied the trephine to the cold-storage eye which an assistant holds by means of sterile gauze. Transferring the donor cornea to the host eye is the work of only a few minutes. Dr. Filatov straps the graft in position with the prepared strip of conjunctiva, withdraws the ivory guard from its slots, bandages both eyes to immobilize the engrafted one as much as possible. After a lapse of weeks the patient can see, adequately...
...goes without saying that the living donor of a cornea should not suffer from syphilis and other infectious diseases or from some infection of the eye. Unfortunately, however, material of this sort is rather scarce and no matter how much one may economize with eyes removed from patients in eye clinics and in hospitals the available number of such eyes will not be sufficient to supply all cases where a transplantation is necessary...
...Naturally enough the idea suggested itself of using cornea from dead bodies. . . . Eyes removed from corpses immediately after death were found to be fit for transplantation. . . . The condition after the operation was pretty much the same as that in the case of cornea taken from live eyes...
...donor's age is apparently irrelevant. An old person's cornea may be successfully transplanted to a young one. The patient's age however might at times make some difference. Thus it is difficult to perform the transplantation in children up to the age of eight or nine years, for it is difficult to take care of them. Blood groups apparently are not of essential significance for the success of the operation...
