Trial Outcomes & Findings for Clinical Comparison of Two Daily Disposable Contact Lenses - Pilot Study 3 (NCT NCT04942925)

NCT ID: NCT04942925

Last Updated: 2022-09-07

Results Overview

Distance visual acuity (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 inferential testing was pre-specified for this endpoint.

Population: Safety Analysis Set: All subjects/eyes exposed to any study lenses evaluated in this study with non-missing response

Distance visual acuity (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.
