History of Iridotomy / Knife-Needle vs. Scissors—Description of Author's V-Shaped Method

by S. Lewis Ziegler

The test for glasses, March 10, 1908, gave the following result:

O. D. S + 12 D ⁐ C + 1.25 D ax. 135° = 20/50.
O. S. S + 12 D ⁐ C + 1.25 D ax. 135° = 20/70.

Add

O. D. S + 5 D = J. 6.
O. S. S + 5 D = J. 12.

These were ordered in biconvex torics, which she now wears with great comfort. It is worth noting that O. S. still retained good visual acuity, although blinded by an injury nearly fifty years before.
