T HE technic of corneal transplantation is a well established procedure. Iridectomy as a preliminary operation is here offered and recommended, for the following reasons :
(1) It enables the surgeon to estimate the amount of postoperative reaction that may follow in the eye concerned ; (2) it allows for more rapid formation of the anterior chamber; (3) there is less likely to be a prolapse of the iris into the wound after the transplantation.
A preliminary iridectomy will enable the surgeon to study the eye involved under operative conditions. This does not apply so rigidly in cases in which an avascular nebulous cornea is present, such as may follow extensive phlyctenular keratitis or a central leukoma resulting from ulcer. But in cases of old interstitial keratitis resulting from syphilis or tuberculosis, in which infiltration is deep and the vascularity potentially marked, it is of value to determine the reaction that may
