    so as to end the traction, stops the process, and this is best done with scissors. I have seen six such cases where iridectomy proved of no avail and relief was only obtained by severing these capsule fibers. Iritis may occur; likewise, irido-cyclitis may result from too rapid swelling of the lens substance. These sequelae are best treated by leeches to the temple, the free use of atropin and hot (from 120° to 130° F.) compresses, continuously applied to the closed eye-lids of the affected eye. These conditions when severe are difficult to diagnosticate from the signs and symptoms due to infection, especially when the process results in panophthalmitis. It is, indeed, a question as to what role infection plays in post-oi^erative uveitis; it is possible that germs may be introduced at the time of the operation. Needling through the dear cornea. Some operators prefer to make the puncture, especially where a small central incision of the anterior capsule is desired, close to the limbus, but within the transparent cor- nea. The technique differs somewhat from the previous operation in that the length of the cut is less and the point of the needle penetrates the lenticular substance somewhat deeper, as shown in the accompany- ing diagram.—(P. A. C.) Cataract, Displacement of. See Cataract, Couching of. Cataract, Dotted. Punctate cataract.

Adherent cataract. Cataracte albumineuse. (F.) (Obsolete). Soft or albuminous cataract. Cataracte argentee. (F.) Cataract having a shining-white or silvery appearance. Cataracte aride-siliqueuse. (F.) Siliquose or wrinkled cataract. Cataracte a trois branches. (F.) A cataract with three radiating strise of opacity. Cataracte azure. (F.) Blue cataract; cataracte eaerulea. One form of cortical cataract in which there is a large number of very small dots or streaks. Cataracte barree. (F.) Barred cataract. Cataracte blanche. (F.)
