Trial Outcomes & Findings for Clinical Comparison of DDT2 Contact Lens and a Daily Disposable Contact Lens - Study 2 (NCT NCT03888482)

NCT ID: NCT03888482

Last Updated: 2020-07-13

Results Overview

Visual acuity was assessed and 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 performed at 8 study centers in the United States (US).

Of the 154 enrolled, 2 were exited from the study as screen failures and 1 subject was randomized but not exposed. This reporting group includes all exposed subjects (151).

PRIMARY outcome

Timeframe: Day 8, each product

Population: Full analysis set (FAS): All randomized subjects/eyes with non-missing responses, who were exposed to any study lenses evaluated in this study, with the exception of the lenses used at Visit 1 for optimization and fitting.

Visual acuity was assessed and 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.
