After-treatment.—The after-treatment of an operation in whichthe eyeball has been opened must be mainly directed to the prevention ofanything that might interfere with the rapid and permanent closure of thewound. For this purpose the eve operated upon is bandaged, in order toput a stop to the movements of the lids; and in operations of any mag-nitude the eye not operated upon should also be kept shut for the first EYE OPERATIONS IN GENERAL 927 day. Furthermore, the patient ought to avoid all physical exertion, asby this the ocular tension is increased, and the recently agglutinatedwound might be forced open again. Hence, after major operations(iridectomy or cataract extraction), the patient is made to stay flat on hisback in bed for the first day, and on the following days is permitted to beup in an arm-chair. For the first few days he is allowed only soft diet, soas to obviate the exertion of chewing. [For other precautions to be observed. Fio. 411.—Inclusion of the Iris with Cystoid Cicatrization after the Extraction ofa Senile Cataract. Magnified 13 X 1. The iris, I, extends from its origin in the ciliary body, C, tothe inner orifice of the wound, so that here the anterior chamber is contracted into a narrow slit. Theiris within the tract of the wound is folded upon itself, the point of flexion corresponding to the exteriorsurface of the sclera. The pupillary portion, P, of the iris extends from the site of the constriction intothe anterior chamber, where it lies free. On its anterior surface may be seen the entrance of a crypt,near its posterior surface the cross section of the sphincter pupillae. Besides the iris, the capsule, k, ofthe lens, is also drawn up to the cicatrix, and has become adherent to it. The section by which theextraction was made cuts in two the line of junction between the sclera, S, and the cornea, H, so thatby its anterior half it lies in the sclera, by its poster
