Trial Outcomes & Findings for Clinical Performance of Two Commercial, Daily Disposable Contact Lenses (NCT NCT05010512)

NCT ID: NCT05010512

Last Updated: 2022-11-08

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 112 enrolled, one subject was exited prior to randomization as a screen failure. This reporting group includes all randomized subjects (111).

PRIMARY outcome

Timeframe: Day 8 (-0/+3), each study lens type

Population: FAS with non-missing response (eye)

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.
