Extended wear soft contact lenses: to market or not to market.
1. Today, cosmetic extended wear lenses have numerous aliases; continuous wear, provisional extended wear, and flexible wear, all referring to the same products, but on a relative scale of wearing time. Cosmetic extended wear lenses are elective and differ from the medical necessity of extended wear that few patients require. Refractive surgery has made significant advances in the cosmetic extended wear lens market. 2. Despite growing conservatism, positive marketing kept growing the EW philosophy for almost a decade until the FDA laid down some new rules, including a 1-week maximum for overnight wear. Coincidentally, this mandate came with the advent of the disposable lens in 1989. Since then, 1-week EW with disposable contacts has proved to be a safer modality for cosmetic EW; however, the concern of corneal complications continues to decline the market. 3. Patients risk a microbial ulcerative keratitis secondary to cosmetic EW. If daily wear contact lens options or occasional part-time EW is not amenable to the patient, refer the patient to an experienced refractive surgeon. Today, patients have more healthful vision choices than ever before.
