Trial Outcomes & Findings for Evaluation of Prototype Lenses With Experimental UV/HEV Blocker (NCT NCT04885296)

NCT ID: NCT04885296

Last Updated: 2022-09-01

Results Overview

Overall quality of vision scores were assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response with a range of 0-120. The average CLUE vision score for each lens type was reported.

PRIMARY outcome

Timeframe: 2-Week Follow-up

Population: All subjects that completed all study visits without a major protocol deviation.

Overall quality of vision scores were assessed using the Contact Lens User Experience™ (CLUE) questionnaire. CLUE is a validated patient-reported outcomes (PRO) questionnaire to assess patient-experience attributes of soft contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65. Derived CLUE scores using Item Response Theory (IRT) follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response with a range of 0-120. The average CLUE vision score for each lens type was reported.
