Trial Outcomes & Findings for Clinical Comparison of 2 Daily Disposable Contact Lenses - Pilot Study 2 (NCT NCT04528017)

Last Updated: 2021-11-11

Results Overview

Distance VA was assessed with study lenses in place. VA was collected for each eye separately using logarithmic of the Minimum Angle of Resolution (logMAR) charts. A logMAR acuity of 0.0 corresponds to 20/20 Snellen acuity (normal visual acuity), with a negative value denoting better than 20/20 visual acuity. No formal hypothesis was predefined for the primary endpoint. No inferential testing was performed.
