This capsule forceps is peculiar in the construction of the grasping jaws; that part of the blades which grasps the capsule is concave and shaped to meet a convex curve with a radius of 10 mm., thus approximating the average convexity of the anterior surface of the lens. On their under surface the blades meet each other exactly throughout their length. Their distal ends are slightly rounded, so that there are no sharp edges or points. The cross section of the blade is triangular, with the base downward, allowing any excess of capsule to well up between the blades without obstruction. Pressure is controlled by a stop, so that the capsule is not crushed. The instrument is made in both a straight action and a cross action model, the latter permitting the surgeon to relax his wrist and fingers while manipulating the lens. There is a tendency, however, to press
