Clinical Evaluation of a Daily Disposable Contact Lens in Symptomatic Weekly/Monthly Lens Wearers
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
- 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.
