Lippman Richard K. O.D. F.A.A.O.Cornea: 1990 Original Article: PDF Only Buy Abstract The Food and Drug Administration (FDA) exercises a multifaceted role in fulfilling its mission of enforcing the Federal Food. Drug and Cosmetic Act (Act), functioning not only as industry regulator and consumer protector, hut also as scientific advisor and consumer educator regarding medical devices, drugs, foods, cosmetics, and veterinary medicine. Medical devices are regulated within the Center for Devices and Radiological Health. Contact lenses are regulated under the authority of the medical device amendments. The Center is responsible for promulgating regulations, publishing guidelines, and developing written guidance in enforcing the Act. and also for guiding manufacturers of medical devices in sale and effective product development. Other components deal with the compliance of manufacturers with the marketing of medical devices within the meaning of the Act. and through labeling requirements of the Act and consumer education and informational activities. As for contact lenses, the process of updating product development regulations and guidelines is an ongoing activity. The most recent version of the Contact Lens Guideline Document, issued in April 1988, contains two major revisions involving preclinical and clinical testing. The first redefines plastics into one materials category, thus reducing testing requirements with respect to animal toxicology studies and other preclinical areas. The second revision restricts clinical testing requirements to allow confirmatory trials in applications for new daily wear lenses. The intention was to maintain the ability of studies to detect major material or design Haws in lenses, thus boosting confidence in their performance while eliminating unnecessary trials. Recent public health issues taken up by the FDA have included a review of human immunodeficiency virus (HIV) transmittance potential through tears, a review of Acanthamoeba keratitis among salt tablet users, and a review of ulcerative keratitis in patients using extended wear soft lenses. New guidance and product labeling changes have been issued in these areas. © Lippincott-Raven Publishers.
