The type of senile cataract suited for this method of intracapsular extraction after subluxation is that in which the capsule is dense enough to hold the grasp of the forceps ; hence, cataracts in patients under 50 years of age are usually excluded. The capsule in the case of a glistening cortex (mother of pearl) ruptures; the sclerosed lens, with posterior cortical opacity, dislocates readily, as do those with a thickened capsule ; the morgagnian cataract is difficult to grasp, as the capsule is elusive, and when finally grasped, it ruptures easily. The section must be large enough, especially in undersized eyes, in which the incision should be scleral throughout.
The operation is contraindicated when the eyes are prominent, when there is a complication due to vitreous disturbance (myopic eyes, soft eyes, cyclitic eyes) and when the patient shows nervousness or restlessness. In any of these cases, the toothed forceps
