In 1892, I published five cases of keratoconus1 which I had treated with galvanocautery.
—Operation was performed on both eyes. On the left eye the apex was cauterized with a fine loop in an area of 2×3 mm. and then pierced, so that the aqueous spurted out. Healing was free from dangerous reaction, but slow. The chamber closed and opened seven times. Before the operation patient read J. 1 at 1" and with —7D. 20/200; eighteen months after the operation he read J. 1 fluently at 10", and with —4D. 20/40. The right eye, on account of the slow healing of its fellow, was cauterized cautiously and repeatedly until I saw the aqueous just begin to ooze out. There was a good deal of reaction, and the lens having become cataractous—by overheating the aqueous—had to be needled. Recovery favorable. Vision with +12D. +4cyl. 20/70. The recovery has
