Trial Outcomes & Findings for Clinical Evaluation of Manufacturing Processes for a Reusable Multifocal Optical Design in a Presbyopic Population (NCT NCT03787472)
NCT ID: NCT03787472
Last Updated: 2020-06-23
Results Overview
Overall 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.

Participant Flow
A total of 45 subjects were enrolled in this study and all 45 subjects were randomly assigned to one of the two lens sequences and completed the study. 3 subjects were excluded from analysis and 42 were included in Per-Protocol Population.

SECONDARY outcome
Timeframe: 2-Week Follow-upPopulation: All subjects who had successfully completed all visits and did not substantially deviate from the protocol as determined by the trial cohort review committee prior to database hard lock.
Binocular visual performance on logMAR (Logarithm of Minimal Angle of Resolution) scale was evaluated under high luminance and high contrast conditions at three distances: Distance (3 meters) was measured using ETDRS (Early Treatment Diabetic Retinopathy Study) charts; Intermediate (64 centimeters) and Near (40 centimeters) were measured using Reduced Guillon-Poling 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.
