The cut surface of corneal stroma from rabbits was studied with a scanning-electron microscope and compared after using a manual trephine, a motor-driven rotor trephine and a rotor trephine with mechanical guidance. It became evident that the cut surface obtained with the motor-driven trephine is clearly smoother than that obtained with manual trephine. A further improvement in the quality of the cut is evident with a mechanically guided trephine.
