 Method consists in friction of the cornea against the

 Method consists in " direct trituration ' ' of the lens

 Both methods are preceded by an iridectomy. C, 

 Black, the lens is pigmented, and of a dark-brown 

 color. C, Capsular, consists in non-transparent de- 

 posits on the inner surface of the capsule. C, Cor- 

 tical, opacification of the outer layers of the lens. C,

 sion of, an operation preliminary to absorption , or ex- 

 traction by suction, consisting in rupturing the capsule, 

 so that the aqueous humor gains access to the lens.

 surgical operation. See Extraction of C. C, Fluid, 

 C. , Lacteal, the breaking up of an opaque lens into a

 name given to the old method of artificial luxation of 

 the lens in cases of cataract. A needle was passed into 

 the sclera on the outer margin of the cornea and into the 

 lens. which was then depressed into the vitreous. Those 



who performed this operation were called cataract- 

 prickers. C, Pyramidal, the opacity is at the an- 

 terior pole and is conoid, the apex extending forward.
