The knife-needle should always be entered through the vascular tissue of the limbus. It should be absolutely sharp, and used so as to cut, not tear. The operation should be done under strong illumination. Two incisions must be made, completely joining each other at a sufficient angle. Attention to these points will render the operation with the single knife-needle efficient for almost all cases of secondary capsular cataract, and make it one of the safest operations of surgery.
