Trial Outcomes & Findings for Evaluation of a Daily Disposable Novel Multifocal Contact Lens in a Myopic Population; Part 2 (NCT NCT04615507)

NCT ID: NCT04615507

Last Updated: 2022-04-01

Results Overview

Binocular visual performance on logMAR (Logarithm of Minimal Angle of Resolution) scale was evaluated at distance (4 meters), intermediate (64 centimeters) and near (40 centimeters) under high luminance high contrast lighting condition using ETDRS (Early Treatment Diabetic Retinopathy Study) charts. The room illuminance was required to be between 7.3 and 7.9 EV (394-597 lux). For Distance (4 meters), the acceptable range for the chart luminance was 10.5-10.7 EV (181 208 cd/m2). For Intermediate (64cm) and Near (40cm), the acceptable range for the chart luminance 10.8-11.1 EV (223-274 cd/m2). Letter-by letter results calculated the visual performance score for each chart read. logMAR scores closer to zero, or below zero, indicate a better visual acuity. A logMAR visual performance score of 0.0 is equivalent to Snellen visual acuity of 20/20.

PRIMARY outcome

Timeframe: 1-Week Follow-up within each wearing period

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

Binocular visual performance on logMAR (Logarithm of Minimal Angle of Resolution) scale was evaluated at distance (4 meters), intermediate (64 centimeters) and near (40 centimeters) under high luminance high contrast lighting condition using ETDRS (Early Treatment Diabetic Retinopathy Study) charts. The room illuminance was required to be between 7.3 and 7.9 EV (394-597 lux). For Distance (4 meters), the acceptable range for the chart luminance was 10.5-10.7 EV (181 208 cd/m2). For Intermediate (64cm) and Near (40cm), the acceptable range for the chart luminance 10.8-11.1 EV (223-274 cd/m2). Letter-by letter results calculated the visual performance score for each chart read. logMAR scores closer to zero, or below zero, indicate a better visual acuity. A logMAR visual performance score of 0.0 is equivalent to Snellen visual acuity of 20/20.

SECONDARY outcome

Timeframe: 1-Week Follow-up within each wearing period

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

Overall 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 leans type was reported.
