Clinical Evaluation of a Daily Wear Monthly Replacement Silicone Hydrogel Lens

Not Applicable

Completed

• Conditions: Refractive Errors
• Interventions: Device: Lehfilcon A contact lenses; Device: Comfilcon A contact lenses; Device: CLEAR CARE

• Registration Number: NCT04178720

Group	Intervention	Description
LID018869	Lehfilcon A contact lenses	Lehfilcon A contact lenses worn in both eyes at least approximately 8 hours per day and approximately 5 days per week during waking hours only. The lenses will be removed nightly for cleaning and disinfection and replaced monthly over the 3-month wear period.

Primary Outcome Measures

Name	Time	Method
Distance VA (logMAR) With Study Lenses - Completed Eyes	Dispense, Week 1 follow-up, Week 2 follow-up, Month 1 follow-up, Month 2 follow-up, Month 3 follow-up (at least 4 hours after lens insertion at each follow-up assessment visit)	Visual acuity (VA) was assessed for each eye individually with study lenses in place at a distance of 6 meters using a letter chart. VA was collected in Snellen and converted to 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. No formal hypothesis testing was planned.
Distance VA (logMAR) With Study Lenses - Discontinued Eyes	Dispense, Week 1 follow-up, Week 2 follow-up, Month 1 follow-up	Visual acuity (VA) was assessed for each eye individually with study lenses in place at a distance of 6 meters using a letter chart. VA was collected in Snellen and converted to 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. No formal hypothesis testing was planned.
