Update report on intraocular lenses.

Intraocular lenses have been regulated by the Bureau of Devices of the Food and Drug Administration since February 9, 1978. One year ago, data were reported through August 9, 1979, at which time more than 177,000 lenses of four different classes had been implanted. In the meantime, appeals and legal action by the Public Citizens Health Research Group of Washington, DC, have resulted in a re-examination of the intraocular lens issue and the FDA study of the lenses, which has resulted in a delay in any premarket approval, and prohibits the public release of the results of the study to date. This sequence of interesting interactions between physicians, manufacturers, the Food and Drug Administration, and a "consumer" group is outlined.

Interim FDA report on intraocular lenses.

Intraocular lenses have been regulated by the Food and Drug Administration since February 9, 1978. Data reported through August 9, 1979 reveal 177,503 lenses of four different classes have been implanted. The anterior chamber intraocular lens appears to have a higher incidence of certain postoperative complications compared with both control operations and implantation of lenses in the other three classes. The anterior chamber intraocular lens appears to be associated with a lower level of visual acuity compared with both control cases and the other three lens classes during the first six months following implantation. Some complications occurred less frequently following implantation of intraocular lenses than in control cases.

The Commission on Ophthalmic standards--the American Optometric Association's standards development program.

The American Optometric Association has been concerned with ophthalmic standards for over fifty years. This paper describes this involvement and how it has led to the creation of the Commission on Ophthalmic Standards. The commission's scope and function and the responsibilities of the Director of Standards Development are given. The progress of the commission's program has been temporarily delayed due to a proposed FTC rule on voluntary standards setting organizations.
