Comparison of the clinical performance of the Acuvue disposable contact lens and CSI lens in patients with giant papillary conjunctivitis.
Anecdotal reports have suggested that the use of disposable contact lenses is an effective treatment for giant papillary conjunctivitis. In a prospective randomized double-masked study, we compared the clinical performance of the Acuvue (Vistakon, Jacksonville, Florida) disposable contact lens to the traditional daily-wear lens of choice, CSI (Pilkington Barnes Hind, Sunnyvale, California), in 37 patients with previously diagnosed giant papillary conjunctivitis who were examined at one-month intervals for six months. A survey questionnaire for grading symptoms disclosed significant improvement in itching, discharge, and blurred vision in both groups early in the study. Evaluation of patient preference showed that the CSI lens was strongly preferred with regard to lens handling (76% vs 8%). In contrast, the Acuvue lens was strongly preferred with regard to lens comfort (62% vs 11%). For the variable of overall lens preference, there was no significant difference between the two lenses (CSI, 43% and Acuvue, 41%). Multiple regression analysis disclosed that both lens comfort (P < .002) and lens handling (P = .05) contributed significantly to the choices made regarding the dependent variable of overall lens preference. Lens comfort (beta = .71) was observed to be approximately 50% more powerful than lens handling (beta = .48). There was no significant difference in the rate or cost of torn lenses between groups, suggesting that the Acuvue lens can withstand the physical manipulation associated with daily-wear use for up to one month. The results of this study suggest that the use of disposable contact lenses for the treatment of giant papillary conjunctivitis is at least as effective as the traditional daily-wear lens of choice.
