Active clinical trials for "Refractive Errors"

The purpose of this study is to demonstrate non-inferiority of a new daily disposable multifocal contact lens in plus powers against the commercially available AIR OPTIX® AQUA MULTIFOCAL (AOAMF) lens in high contrast/high illumination (HC/HI) near visual acuity (VA).

The aim of this study is to assess visual performance of prototype soft contact lens designs compared to commercially available contact lenses over one-week of lens wear.

This study seeks to evaluate the clinical and subjective performance of two established soft contact lenses.

The purpose of this study is to compare the wettability of contact lenses disinfected with three marketed contact lens care solutions.

The results of this trial will demonstrate that AVSS software performs as intended and is acceptable in a clinical setting.

The purpose of this study is to compare visual acuity between two daily disposable contact lenses.

The primary objective is to evaluate corneal staining observed after 2 hours of wear with contact lenses with investigational coating against PureVision™ lenses, all pre-cycled with OPTI-FREE® RepleniSH® multi-purpose disinfection solution.

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 compare AIR OPTIX® plus HydraGlyde (AOHG) contact lenses to ACUVUE® VITA® (VITA) contact lenses for total lipid uptake (total of surface and bulk uptake) after 30 days of wear by high lipid depositors.

The purpose of this study is to explore overall vision with BIOFINITY® ENERGYS™ contact lenses as compared to BIOFINITY® contact lenses after one week of wear.
