Filter by:The objective of this study is to compare the ease of removing two daily disposable soft contact lenses off the eye.
The purpose of this study is to compare the amount of coma as measured by aberrometry induced by two silicone hydrogel toric lenses in astigmatic participants.
The purpose of this study was to compare three CE-marked daily disposable contact lenses for tear film stability as measured by pre-lens non-invasive keratograph break up time (PL NIK-BUT). Secondarily, contact lens surface wettability was assessed.
The purpose of this study is to evaluate the accuracy and repeatability of an individually validated prototype autorefractor designed to be mounted on a surgical microscope.
The purpose of this study was to compare lens comfort on Day 30 for Air Optix® lenses cared for with OPTI-FREE® PureMoist® (OFPM) Multi Purpose Disinfecting Solution (MPDS) compared to Acuvue® Oasys® lenses cared for with habitual MPDS.
The purpose of this study was to demonstrate substantial equivalence of the new DAILIES® AquaComfort Plus® Multifocal (DACP MF) contact lens to the commercially available Focus® DAILIES® Progressives (FDP) contact lens.
The purpose of this study was to evaluate overall satisfaction with AIR OPTIX® COLORS as compared to FRESHLOOK® COLORBLENDS contact lenses.
The purpose of this study is to evaluate the lipid uptake, wetting characteristics, and visual performance of AIR OPTIX® AQUA and ACUVUE® OASYS® with HYDRACLEAR® contact lenses when used in conjunction with two contact lens care systems.
The purpose of the study is to investigate the corneal epithelial cell response associated with lens wear that results in solution-induced corneal staining (Phase1) and to determine the cell appearance in symptomatic and asymptomatic contact lens wearers (Phase 2).
The purpose of this study is to obtain objective and subjective clinical data to compare the performance of two soft contact lenses.
