Text-book of ophthalmology . Fig. 403 Fig. 404 Fig. 405 Fig. 403.—Normal Position of the Iris. Magnified 2X1. The flap incision for the ex-traction, S Si, lies in the sclera. The angles of the sphincter, a and oi, are both low down. Fig. 404.—Incarceration of the Iris in the Wound (after a Corneal Flap Extraction).Magnified 2X1. The flap incision for the extraction, s si, lies in the cornea. The iris is visible as adark nodule, i, in the wound, and the angle, ai, of the sphincter on the same side appears drawn up incomparison with that of the other side, which is in its proper position.

Thepupil is drawn toward the cicatrix, N. ceration takes place because either the out-gushing aqueous or the lens thatis pushed out by the pressure forces the iris into the wound. If an iridec-tomy is made, the iris, which is grasped by the forceps in front of the wound(Fig. 406, aa)} is cut off flush with the latter. When this is done, of course
