Trial Outcomes & Findings for Clinical Assessment of Two Reusable Silicone Hydrogel Contact Lenses (NCT NCT05050578)

NCT ID: NCT05050578

Last Updated: 2023-03-16

Results Overview

Visual acuity (VA) was collected for each eye individually with study lenses in place at a distance of 4 meters using a letter chart. VA was measured in logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with a lower logMAR value indicating better visual acuity.

Participant Flow

Subjects were recruited from 10 investigative sites located in the United States.

Of the 166 enrolled, 3 subjects were exited from the study prior to randomization as screen failures, and 1 randomized subject was discontinued prior to exposure to the study lenses. This reporting group includes all subjects exposed to the study lenses, as treated (162).

PRIMARY outcome

Timeframe: Day 30, each study lens type

Population: Full Analysis Set: All randomized subjects who were exposed to any study lenses evaluated in this clinical study with data at Day 30.

Visual acuity (VA) was collected for each eye individually with study lenses in place at a distance of 4 meters using a letter chart. VA was measured in logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen visual acuity (normal distance eyesight), with a lower logMAR value indicating better visual acuity.
