Trial Outcomes & Findings for Clinical Evaluation of Senofilcon A Contact Lenses Using a Novel Manufacturing Technology to Evaluate Overall Visual Acuity. (NCT NCT05361304)

NCT ID: NCT05361304

Last Updated: 2023-07-13

Results Overview

Monocular visual acuity was measured on a logMAR (Logarithm of Minimal Angle of Resolution) scale under high luminance low contrast (HLLC), and low luminance high contrast (LLHC) at distance (4 meters) using an ETDRS (Early Treatment Diabetic Retinopathy Study) charts. 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: 2-Week Follow-up

Population: All subjects who successfully completed all study visits without a major protocol deviation at 2-Week Follow-up evaluation.

Monocular visual acuity was measured on a logMAR (Logarithm of Minimal Angle of Resolution) scale under high luminance low contrast (HLLC), and low luminance high contrast (LLHC) at distance (4 meters) using an ETDRS (Early Treatment Diabetic Retinopathy Study) charts. 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: 2-Week Follow-up

Population: All subjects who successfully completed all study visits without a major protocol deviation at 2-Week Follow-up evaluation.

Average daily wear time was assessed by calculating the number of hours between subjects reported time of insertion and time of removal of the study lenses, on an average day.

SECONDARY outcome

Timeframe: 2-Week Follow-up

Population: All subjects who successfully completed all study visits without a major protocol deviation at 2-Week Follow-up evaluation.

Subjective vision was 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 comfort score for each lens type was reported.
