The seizing of the iris presents difficulties in many cases of iridectomy. Although the incisions may have been properly made, and the forceps introduced in the usual manner, either they do not seize the iris at all, or only tear out a small piece of it. . . .
For such cases I have now had the situation of the teeth of the forceps altered, in such a manner that the surface in which they grasp is turned to a right angle.
