Filter by:The purpose of this study was to evaluate the subjective and objective performance and the physiological response to AIR OPTIX® COLORS soft contact lenses compared with AIR OPTIX® AQUA contact lenses in participants with normal eyes and prescription needs.
Proof of concept study to compare the best corrected visual acuity obtained via First-Sight lenses with the autorefraction in children.
Proof of concept study is to compare the best corrected visual acuity obtained via First-Sight lenses with the clinical "gold standard" of manifest refraction and autorefraction.
By using a new software two consecutive laser treatments have been combined to correct the distance vision and to provide a near vision component in addition to the first treatment. This study will help us to answer 2 questions: 1. How accurately this combined technique corrects distance and near vision 2. Whether the correction is adequate to remove the complete need for supplementary near spectacles
The purpose of this study is to utilize in-vivo confocal microscopy to describe differences in corneal epithelial immune status across three lens care regimens in new contact lens wearers.
The purpose of this three-month study is to compare the quality of life and ease of fit among children wearing investigational single-vision contact lenses, commercially marketed single-vision contact lenses, and commercially marketed multifocal contact lenses.
The results of this trial will demonstrate that the iDesign System performs as intended and is acceptable in a clinical setting.
The purpose of this study was to assess the comfort of OPTI-FREE RepleniSH in soft contact lens wearers.
The purpose of this trial was to evaluate the factors affecting comfortable contact lens wear and how those factors affect contact lens replacement frequency.
This study seeks to evaluate the clinical performance of two daily disposable contact lenses.
