Filter by:The purpose of this study is to compare the visual acuity of an investigational silicone hydrogel to a commercially available silicone hydrogel in contact lens wearers.
The purpose of this study is to evaluate the impact of back surface molded marks (MM) applied to delefilcon A contact lenses as measured by the incidence of ocular discomfort device-related adverse events with DAILIES TOTAL1® Multifocal contact lenses with molded marks (DT1 MF MM) and current DAILIES TOTAL1® Multifocal contact lenses (DT1 MF).
Subjects will wear 2 of 2 study contact lenses for a wearing time of approximately three to four hours at each of the visits in order to take measurements on binocular functional visual performance.
The purpose of this study is to evaluate DAILIES TOTAL1® Multifocal (DTl MF) contact lenses in current multifocal contact lens wearers with symptoms of end of day discomfort compared to their habitual multifocal contact lens correction.
The purpose of this study is to evaluate the safety and efficacy of FID 120947A in soft contact lens wearers of Japanese ethnicity.
The purpose of this study is to compare the lens fit characteristics, specifically lens centration, of ACUVUE® OASYS® 1-DAY (AO1D) contact lenses and DAILIES TOTAL1® (DT1) contact lenses.
The purpose of this study is to compare DAILIES TOTAL1® (DT1) to 1-DAY ACUVUE® TruEye® (TE) for Investigator-rated successful lens centration in Japanese population.
