A.)Arlts iris punch. Von Arlt first devised and recommended a punchfor cutting out a piece of occluding pupillary membrane and theiris attached to it. After an incision through the cornea and iriswith a keratome he entered the anterior chamber with the punch(with closed beak) and allowed it to open far enough to get the irisdiaphragm between the two blades. Then, on closing the blades with. Arlts Iris Puncli. firm pressure, a piece of the diaphragm is punched out and with-drawn.— (A. A.)Arlt-Jaesche operation for trichiasis. An intermarginal incision ismade along the whole length of the lid, following the gray line onthe free border. This incision should be 3 or 4 mm. in depth, andshould be so placed that all the lashes will be in the anterior layerw^hich is separated from the tarsus. A fold of skin is next removedfrom the anterior surface of the lid in the following manner. Anincision is made in the skin parallel to the free border and about4 mm. from it; above this and joining it at each end, there is madea curved incision through the skin, w^hich marks out a crescenticarea of skin that at its widest part at the middle of the lid is about8 mm. This crescentic piece of skin is then dissected off with blunt-pointed scissors or scalpel, care bei
