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 high-oxygen water gradient surface to minimize mechanical friction or the infusion of osmoprotectants and electrolytes to prevent hyperosmotic stress. This study addresses the gap in providing a sustainable, all-day wearing experience that preserves both physiological health and the precise optical clarity required for multifocal success.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants currently wearing INFUSE One-Day Multifocal (kalifilcon A) are refit into DAILIES TOTAL1 Multifocal (delefilcon A) daily disposable contact lenses and followed for approximately 3 weeks.
Device: DAILIES TOTAL1 Multifocal (delefilcon A)
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.
Proportion of participants with Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) score <12
The Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) is an 8-item validated questionnaire assessing the frequency and intensity of contact lens-related dryness and discomfort. Total scores range from 0 to 37, with higher scores indicating greater dryness and discomfort (worse symptoms). A score of less than 12 indicates asymptomatic status. The primary endpoint is the proportion of participants achieving a CLDEQ-8 score \<12 after 2 weeks on their finalized DAILIES TOTAL1 Multifocal prescription. Results will be reported with exact (Clopper-Pearson) 95% confidence intervals.
Time frame: 2 weeks after wearing finalized DAILIES TOTAL1 Multifocal prescription (Visit 3, ~Day 21)
Plan to share: Undecided
Started May 2026 (actual). Primary completion is estimated for Jan 2027, 8 months after the start.
Of 42 non-industry interventional studies with no phase under Presbyopia, half reached primary completion within 15 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 23. This study's planned 8 months is below that.
Counting every sponsor, half of 129 studies reached it within 10 months; a quarter within 3 and three quarters within 23.
