In the same class of cases in which discission is employed, or in which itis not desired to repeat the needling, linear extraction may be used. Thisoperation is applicable especially in soft congenital cataracts and in completejuvenile cataracts in patients under thirty years of age. It is also used intraumatic cataract, and in cases in which needling has been followed byswelling with glaucomatous symptoms. For high progressive myopia, somesurgeons practise discission, followed by extraction or removal by pupil should be widely dilated. A keratome is inserted at a point i the periphery of the cornea. The instrument is passed onwarduntil a wound 5 mm. in width is made. Through this the cystotome is.

Pressure is made with aspoon or spatula against the cornea below while pressure is also made abovethe wound. The pressure should be gentle lest the hyaloid be ruptured andvitreous escape. Some surgeons insert a fine canula connected with rubbertubing by means of which the soft lens is removed by suction. Extraction of the lens without incision of the capsule is in favor with somesurgeons. The first stages of the operation are similar to the ordinary opera-tion. It may be done with or without iridectomy. The lens may be liftedout by means of a curet or loup. Henry Smith perfected this surgeons in India deliver the lens through the
