The disadvantage of most retinal detachment pins is that they have a tendency to become displaced prematurely. To overcome this difficulty, at least in part, new flatter rounded pins and special forceps * have been devised which minimize premature displacement of the pins. It has been pointed out by Pischel1 that the perforating pin is theoretically the ideal electrode. In 1934 Šafář2 called attention to the greater safety of operations when pins were used.

Description of the Pins and Forceps  The round-headed stainless steel pins (Figure, A) which are available in 0.5 mm., 1.5 mm., and 2.5 mm. lengths, have slightly curved upper and lower surfaces which permit the pins to be placed snugly against the sclera. The curve of the posterior surface of the pin lessens the area of surface diathermy, which minimizes necrosis of the sclera and the healing process. As it is usually desirable to combine
