Performance Evaluation of Different Daily Disposable Multifocal Contact Lenses

This was a prospective, randomized, participant-masked, crossover, bilateral dispensing study. Each lens type was worn for approximately 3-4 weeks: the lens prescription of each lens type was optimized after a 3-8 days wearing experience, then participants began a 2 week (14-21 day) wear period.

• Had read and signed an information consent letter;
• Self-reported having had a full eye examination in the previous two years;
• Anticipated being able to wear the study lenses for at least 8 hours a day, 5 days a week
• Were willing and able to follow instructions and maintain the appointment schedule;
• Habitually wore multifocal soft contact lenses, for the past 3 months minimum

• Maximum of 7 participants per site were habitual wearers of daily disposable lenses
• Maximum of 3 habitual wearers per site of 1-Day Acuvue Moist Multifocal
• Maximum of 1 habitual wearer per site of ACUVUE OASYS MAX 1-Day MULTIFOCAL
• Maximum of 3 habitual wearers per site of MyDay Multifocal
• Maximum of 7 participants per site were habitual wearers of frequent replacement lenses
• Maximum of 1 habitual wearer per site of ACUVUE OASYS for PRESBYOPIA
• Had refractive astigmatism no higher than -0.75DC in each eye;
• Were presbyopic and required a reading addition of at least +0.75D and no more than +2.50D;
• Could be fit and achieved binocular distance vision of at least 20/30 Snellen (or +0.20 logMAR) which participants also deemed to be 'acceptable', with the available study lens parameters (powers +4.00 to -6.00DS, near addition as per study design)
