Trial Outcomes & Findings for Clinical Comparison of Two Daily Disposable Contact Lenses (NCT NCT04865354)

Last Updated: 2022-07-06

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.

Participant Flow

This study was conducted at 8 investigative sites in the United States.

Of the 170 enrolled, 3 subjects were exited prior to randomization as screen failures. This reporting group includes all randomized subjects (167).
