By the use of Lens-Antigen alone: 1. Almost every case of cataract in its earliest incipiency can be arrested, even though spiculae or riders may not be absorbed. 2. Immature cataracts, up to 50% of loss of function, can be arrested in over 90% of the cases; and in over 65% of the cases, the vision improved. 3. In mature, or ripe cataract, the greater mass of the cataract(cortical layers) can be absorbed, but it requires a prolonged course of treatment, and besides, the nucleus is not absorbed.
