Trial Outcomes & Findings for Comparison of Clinical Performance of Two Monthly Replacement Toric Soft Contact Lenses (NCT NCT06165627)
NCT ID: NCT06165627
Last Updated: 2025-05-29
Results Overview
Visual Acuity (VA) was assessed for each eye individually with study lenses in place while reading letter charts. VA was recorded in logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen VA (normal distance eyesight), with lower logMAR values representing better eyesight.

Participant Flow
Of the 67 enrolled, 1 participant was discontinued following randomization but prior to exposure to the study lenses. This reporting group includes all participants exposed to any study lenses evaluated in this study (66).

Lehfilcon A toric contact lenses worn in Period 1, followed by comfilcon A toric contact lenses worn in Period 2, as randomized. The study lenses were worn bilaterally (in both eyes) during waking hours for at least 12 hours per day during each wear period (30 days \[-1/+3\] according to randomization assignment). Study lenses were removed daily for cleaning and disinfection with CLEAR CARE Cleaning \& Disinfecting Solution.

PRIMARY outcome
Timeframe: Day 30 of each wear period. A wear period was 30 days [-1/+3 days] according to randomization assignment.Population: Safety Analysis Set: All subjects/eyes exposed to any study lenses evaluated in this study with non-missing response. Note, One subject in the Biofinity Toric arm lost a lens on the way to the visit. Hence, the assessment was taken on 1 eye only.
Visual Acuity (VA) was assessed for each eye individually with study lenses in place while reading letter charts. VA was recorded in logarithm minimum angle of resolution (logMAR). A logMAR value of 0 equates to 20/20 Snellen VA (normal distance eyesight), with lower logMAR values representing better eyesight.
