PURPOSE. To determine if SAC symptoms can be releived among contact lens wearers who change to daily disposable contact lenses. METHOD. 112 habituated contact lens wearers who had SAC were randomized to receive either a new supply of their habitual lenses or the Focus DAILIES lens in a 1 month study during a period of high pollen counts in the U.S. Clinical exams were at baseline and 1 month and wearers completed a daily dairy. Patients continued with their habitual strategies for managing SAC, including medications.
RESULTS. Statistically significant benefits were found for the SAC-related symptoms of burning and redness for all patients in the study. Among a subset of patients who reported a pre-study history of always experiencing one or more SAC symptoms, a statistically significant benefit was found for burning, redness, and also watering. No increase in daily average wearing time was found.
CONCLUSIONS. SAC sufferers who wear contact lenses may experience releif from some SAC-related symptoms by wearing this daily disposable lens.
