Evaluation of indications for cataract surgery.

The large number of cataract operations performed in the United States annually has raised questions as to the indications and methods of documentation. The criteria designed for the Physicians and Surgeons Review Organization (PSRO), the thrust of second opinions, and an evaluation of the types of cataracts producing visual impairment are discussed. The contralight test of Junker is demonstrated as a means of determining the effect of cataracts on visual acuity and could be used as an indicator of the need for surgery.
