Trial Outcomes & Findings for The Clinical Performance of Two Reusable Silicone Hydrogel Contact Lenses (NCT NCT05766787)

NCT ID: NCT05766787

Last Updated: 2024-06-13

Results Overview

Visual acuity (VA) was assessed for each eye individually with study lenses in place using logarithmic of the Minimum Angle of Resolution (logMAR) reading charts. LogMAR values typically range from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). A logMAR acuity of 0.0 corresponds to 20/20 Snellen acuity (normal distance visual acuity), with a negative value denoting better than 20/20 visual acuity.

Participant Flow

Participants were recruited from 15 investigative sites located in the United States.

Of the 190 enrolled, 3 participants were exited prior to randomization as screen failures. Of the 187 randomized, 1 participant was discontinued prior to exposure to the study lenses due to ocular pre-treatment adverse events. This reporting group includes all participants exposed to any study lenses (186).

PRIMARY outcome

Timeframe: Week 1 of each lens product worn during the corresponding crossover period

Population: Full Analysis Set: All randomized subjects who were exposed to any study lenses evaluated in this study with data at Week 1 visit.

Visual acuity (VA) was assessed for each eye individually with study lenses in place using logarithmic of the Minimum Angle of Resolution (logMAR) reading charts. LogMAR values typically range from -0.3 (20/10 vision on the Snellen chart) to 1 (20/200 vision). A logMAR acuity of 0.0 corresponds to 20/20 Snellen acuity (normal distance visual acuity), with a negative value denoting better than 20/20 visual acuity.
