Vision care benefits and optometric services in HMOs.

General eye care, although not a required basic health service of federally qualified health maintenance organizations (HMOs), is being offered in virtually all HMOs. Reasons for including vision care benefits and optometric services are presented. Data from the Group Health Association of America and the Department of Health and Human Services demonstrates that HMOs are in fact providing vision care benefits and optometric services. The growth of the independent practice association (IPA) model is significant for optometry as it threatens to limit the scope of optometric practice. New professional problems arise as participating optometrists are constrained from performing the full range of optometric services. In recent years optometry has expanded its scope of licensure and practice to incorporate both diagnostic and therapeutic drugs in its management of visual problems. Managed care and alternate delivery systems, however, may restrict the advances that optometry has made in the legislative arena.
