Abstract Two retrospective studies with a total patient population of 4,387 myopic, cosmetic contact lens wearers were conducted between February 1987 through December 1989 in both the U.S. and Denmark. The objective of the studies was to compare the disposable contact lens to other known conventional contact lens modalities, and compare the rate of occurrence of complications and symptoms between them. The domestic study included over 2,000 contact lens wearers selected from eye care practitioners across the country. Statistical analysis showed the prevalence of complications with conventional extended wear to be 40% higher than the disposable lens and 50% higher than with conventional daily wear. Fewer patients, in the disposable lens group, reported symptoms at scheduled visits when compared to both conventional daily wear and conventional extended wear patients. Disposable lens wearers also had a lower rate of unscheduled visits for complications and symptoms and the overall result proved the disposable lens to be significantly superior to extended wear lenses (p=0.05). The Danish study showed prevalence of complications that were significantly lower for disposable daily wear lens users than for conventional daily wear lens users. In particular, the daily wear disposable lens was found to have significantly lower prevalence rates for corneal abrasion, corneal edema and sterile punctate keratitis. Statistical analysis indicated the prevalence of complications 24% higher with conventional daily wear when compared to disposable daily wear, with fewer symptoms reported and less unscheduled visits for complications and symptoms (p=0.0003).
