Attempts have been made to transplant a button of clear cornea of
a dog, rabbit, or cat to the cornea of a human being, opaque as
the result of ophthalmia, and von Hippel has devised a special
method of doing this. Recently Fuchs has reported his experience
in cornea-grafting in sections, as a substitute for von Hippel's
method, in parenchymatous keratitis and corneal staphyloma, and
though not eminently successful himself, he considers the
operation worthy of trial in cases that are without help, and
doomed to blindness.
John Hunter was the first to perform the implantation of teeth;
and Younger the first to transplant the teeth of man in the jaws
of man; the initial operation should be called replantation, as
it was merely the replacement of a tooth in a socket from which
it had accidentally or intentionally been removed. Hunter drilled
a hole in a cock's comb and inserted a tooth, and held it by a
ligature. Younger drilled a hole in a man's jaw and implanted a
tooth, and proved that it was not necessary to use a fresh tooth.
Ottolengni mentions the case of a man who was struck by a ruffian
and had his two central incisors knocked out. He searched for
them, washed them in warm water, carefully washed the
teeth-sockets, and gently placed the teeth back in their
position, where they remained firmly attached.
