These scissors have been found satisfactory for cutting dense secondary membranes, where de Wecker's scissors or Noyes' scissors would ordinarily be used, and for performing iridocapsulotomy.
As the blades of the scissors are very thin and narrow, they may be introduced into the anterior chamber through a 2.5 mm. subconjunctival opening made at the limbus, a narrow Agnew keratome being used.
This method is probably the one of choice, although the instrument was primarily designed to penetrate the limbus subconjunctivally without making a keratome incision.
DESCRIPTION OF SCISSORS
The blades are 14 mm. long, pointed and slightly curved, and are held closed by a strong spring. One blade is the direct extension of the octagonal handle, which is 14 cm. in length. The other blade, which is movable, is activated by an arm (A), 48 mm. in length. This arm is joined to an arm (B)
