If, on the contrary, the patient gives evidence of a certain amount of self-control, if the lens escapes readily, if its margin is unbroken, if cortical debris come freely away, if the iris is not unduly stretched during the passage of the lens, if it afterwards falls readily into its place and does not display a tendency to prolapse, we may then reasonably hope to preserve a central and moveable pupil. If, however, the lens is delivered with difficulty, if the iris has manifestly been roughly treated, if it is torn, if portions of uvea have been brushed off, if there is a suspicion that particles of lens matter are lurking behind its uncut surface— above all, if it shows a marked tendency to prolapse, we must excise a portion, but always with regret and only to prevent subsequent disaster. You may ask. What advantage do we get by excising a portion of iris ? Well, the iridectomy prevents prolapse—that bugbear of the old flap operation; prevents bruising of the iris if done before the operation or before the exit of the lens, and the consequences of bruising if done after; permits more easy exit of the lens through a smaller wound, and also complete evacuation of cortical debris, 80 apt to be left behind, and cause subsequent inflammatory mischief when concealed behind the uncut membrane. On the other hand, when the iris is excised there is more cut surface, more wound exposed to the danger of infection and suppuration. The dissection of iridectomised eyes shows almost invariably adhesions at the angles of the wound, whatever precautions may have been taken to prevent them; the eye is visibly mutilated; and although the sight of a patient with an up-
