Trial Outcomes & Findings for Clinical Evaluation Of Two Daily Disposable Contact Lenses And A Monthly Replacement Lens (NCT NCT01151371)

NCT ID: NCT01151371

Last Updated: 2018-06-19

Results Overview

Contact Lens User Experience (CLUE)TM questionnaire: A validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.
