The purpose of this paper is to present the evolutionary stages through which my work on corneal transplantation in cooperation with Dr. Sanford R. Gifford has passed. Certain technics have been modified and others discarded.
At first an apron conjunctival flap was used, according to the Filatov1 technic. A review of the Russian and French literature reveals that Filatov has modified and changed his trephine operation2 several times and completely discarded his prophylactic spatula.
The conjunctival flap was discarded because :
Occasionally the edges of the transplant had a tendency to protrude.
