[The conditions of motor trephining and their influence on time and velocity in cutting the isolated cornea (author's transl)].
A special experiment was constructed to measure the influence of factors such as trephine diameter, revolutions per second, sharpness, and cutting pressure on the incision velocity and incision time for a number of trephine specimens. These measurements show the characteristics of trephines. Different degrees of sharpness were determined by comparison of the characteristics. The dependency of rotation moment transferred to tissue, of revolutions per second, and of incision power is discussed. The results are discussed, and proposals are made to increase safety by application of motor trephines and to develop them further.
