Study Details

Study Description

Brief Summary

The purpose of this study was to evaluate the reduction of contact lens-related dryness symptoms when symptomatic weekly/monthly contact lens wearers were switched to DAILIES® AquaComfort Plus® lenses for a two-week period using composite scores on the Contact Lens Dry Eye Questionnaire (CLDEQ).

  • Outcome Measures

    Primary Outcome Measures

    1. Mean Change From Baseline in Contact Lens-Related Dryness Symptoms at Week 1 and Week 2 [Baseline, Week 1, Week 2]

      Contact lens symptoms were evaluated using the Contact Lens Dry Eye Questionnaire (CLDEQ). Subjects rated 8 common contact lens-related ocular surface dryness symptoms at Baseline, Week 1, and Week 2 using a 5-point scale (1=never or not at all intense, 5=constantly or very intense). A scoring algorithm was used to calculate a composite score for each visit for all symptoms (-6.5 to 10). A higher composite score would indicate more contact lens related dry eye and a lower score, less contact lens related dry eye.
