Research summary
Presbyopia is s a condition associated with aging in which the eye exhibits a progressively diminished ability to focus on near objects. When correcting presbyopia with contact lenses, multifocal designs are used to correct vision at far,
intermediate and near distances.CooperVision presbyopia program has led to the improvement of clariti® Multifocal 1day with a new contact lens design called Invigor Multifocal.
This dispensing study is a verification study of the overall visual satisfaction and visual performance of the Invigor contact lenses worn under normal wearing conditions (daily disposable for a week) in comparison to another multifocal contact lenses (control: 1-Day Acuvue® Moist Multifocal) that is well accepted and extensively used by the presbyopic population.
Up to 150 existing multifocal contact lens wearers will be screened. There will be three study visits over a two-week period. Participants will wear both contact lens types (test: Invigor Multifocal, control:1-Day Acuvue Moist)in a randomised sequence. Both contact lenses are CE marked and each lens type will be worn for a week on a daily wear, daily disposable basis. Both participant and investigator will be masked.
