To the Editor:  —I have read Dr. Frank C. Parker's paper on a cataract operation to reduce the incidence of prolapse of the iris and his instruction on the movements of the iris during the incision with great interest (Arch. Ophth. 20: 597 [Oct.] 1938). Like him, I have had an occasional prolapse after simple extraction of a cataract, but I adopted the small peripheral iridectomy to allow the fluid behind the iris to escape through the wound without prolapse of the iris. Since adopting this simple procedure many years ago, I have scarcely ever had a prolapse.The only difficulty was that when iridectomy was done first the lens attempted to come through the coloboma instead of through the pupil. For some time I have done the peripheral iridectomy after the extraction, and this has been entirely satisfactory.One drop of physostigmine salicylate after the operation insures firm contraction
