    disturbing the iris, employing eserine to preyent the; prolapse which otherwise might occur. The instru- ments required are, a knife double the width of thati of Grmfe, a cystotome, and a small vulcanite spatula, k The steps of the operation are briefly as follows : if: the right eye be the one to be operated on, the operator,' standing or sitting behind the patient, raises the eyelid: with the forefinger of his left hand, and an assistant: fixes the eye with a foreeps. If it be the left eye, the operator coming in front of the patient, the assistant: raises the eyelid and the operator fixes the eye with a forceps held in the left hand. He next detaches thes upper third of the cornea from its insertion into thei sclerotic. Fixation is abandoned when the incision is: made and the flap is being completed. So as to avoid] the bleeding which would interfere with the extraction! of the crystalline and the introduction of the cystotome,, the section is completed without forming the conjunc- tival flap, the cutting edge of the knife being directed: slightly forwards. The second step in the operation con- sists in opening the capsule with the cystotome. The; operator now raises the upper eyelid and directs the pa- tient to look a little downwards j he then exercises a: gentle pressure on the corresponding lip of the wound,. at the same time that, with the help of the lower eyelid; applied against the lower part of the cornea, he pushes: the crystalline upwards. The pupil is cleansed com-- pletely after the evacuation of the lens, and then, if it; so requires, the iris is reduced by the spatula, which is: gently inserted into the anterior chamber between the. lips of the wound, pushing the iris softly before it. Before the patient lies down eserine is instilled into the eye, and, again, when the operation is comph-ted and the .
