Trial Outcomes & Findings for Evaluating Visual Acuity and Initial Fit Performance of Two Soft Contact Lenses (NCT NCT04954833)
NCT ID: NCT04954833
Last Updated: 2025-04-27
Results Overview
Visual acuity on logMAR (Logarithm of Minimal Angle of Resolution) scale was evaluated at distance (4 meters) under high luminance high contrast lighting condition using 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 0.00 is equivalent to Snellen visual acuity of 20/20.

PRIMARY outcome
Timeframe: 10 minutes post lens insertionPopulation: Subjects that completed all study visits without a major protocol deviation.
Visual acuity on logMAR (Logarithm of Minimal Angle of Resolution) scale was evaluated at distance (4 meters) under high luminance high contrast lighting condition using 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 0.00 is equivalent to Snellen visual acuity of 20/20.

SECONDARY outcome
Timeframe: 10 minutes post lens insertionPopulation: All subjects that were fitted at least one study lens
Lens fit acceptance was assessed post lens fitting for each subject eye using a biomicroscope. Acceptable fit was a binary response where Y=1 if lens fit was deemed acceptable by the investigator and Y=0 otherwise. An unacceptable fit was observed if any of the following criteria were met: 1.) limbal exposure at primary gaze or with extreme eye movement, 2.) edge lift, 3.) excessive movement in primary and up gaze or 4.) insufficient movement in the three conditions- primary gaze, up gaze and Josephson push up. Time Frame 10 minutes post lens insertion
