The purpose of this study is to determine the comfort and vision of DAILIES TOTAL1 Multifocal contact lenses in a population of satisfied INFUSE One-Day Multifocal contact lens wearers
There is a paucity of data on the wear experience of DAILIES TOTAL1 Multifocal contact lenses in a population that has previously worn INFUSE One-Day Multifocal. While existing multifocal lenses provide adequate refractive correction, they often fail to maintain the complex biochemical homeostasis of the aging tear film, leading to significant "end-of-day" discomfort and fluctuating vision as the lens surface dehydrates. There remains a critical clinical need for a lens material that doesn't simply offer physical lubrication, but actively mimics the eye's natural environment-either through a h…
Inclusion Criteria: Age ≥40 years at enrollment Current satisfied wearer of Bausch + Lomb INFUSE One-Day Multifocal (kalifilcon A) in both eyes; Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) score \<12 at baseline Minimum contact lens wear of ≥8 hours/day, ≥5 days/week, for ≥30 days prior to Visit 1 Best-corrected distance visual acuity ≥20/25 (0.18 LogMAR) or better in each eye Manifest refraction within study lens parameters (Sphere: +6.00 D to -10.00 D; Add: Low, Medium, High) Willing to wear DAILIES TOTAL1 Multifocal lenses for ≥8 hours/day, ≥5 days/week and complete all study questionna…
Daily disposable multifocal contact lens refit to match the participant's habitual INFUSE One-Day Multifocal power and add level. Worn a minimum of 8 hours/day, at least 5 days/week for approximately 3 weeks. A mandatory \~15-minute equilibration period is required before over-refraction at the fitting visit. Power is finalized at Visit 2 if adjustment is needed; the primary endpoint is assessed after 2 weeks on the finalized prescription.
