The object of the operation is to make a slit in the iris, with the hope that its edges will retract, leav- ing a permanent opening to serve as a new pupil. Sometimes the slit is made simply by a knife passed through the cornea and iris. Special instruments have been devised for the operation, such as the scissors of M. de Wecker [Paris, 19th cent.].

An opening is made near corneal margin, a little to one side of adhesion which it is proposed to loosen. Blunt, flattened hook then passed in and made to tear through attachment. (Streat- field's method.) Or, an incision having been made near the edge of the cornea, the iris is grasped, by a pair of curved forceps, near the adhesion, which is then loosened by traction made toward the periphery.
