In doing operations on the lids requiring incisions of the external parts in animals the hair should be shaved from the part incised, so that it will not be caught in the wound when the sutures are applied. The same antiseptic and aseptic precautions should be used as in doing operations on other portions of the Fig. 9.—Knapp's lid clamp.

The lid clamp or horn spatula (Fig. 9) should be placed beneath the lid to afford more resistance and firmness when making incisions and to protect the eyeball. This should be supported and gently raised by an assistant during the operation. The illustrations of these operations are shown on the human eye, and are taken from Dr. de Schweinitz's work on "Diseases of the Eye," published by W. B. Saunders Co.

The skin is undermined, and the central portion elevated, when the whole is brought together as shown in Fig. n. This allows a more lax condition of the skin of the lid, and is a good operation in ectropion following small cicatrices. Success has been attained in numerous cases by the writer by doing the Kuhnt-Szymanowski operation, whichis described as follows ...
