Active clinical trials for "Refractive Errors"

The purpose of this study is to evaluate lens centration and subjective impressions of DAILIES® AquaComfort Plus® (DACP) lenses compared to 1-DAY ACUVUE® MOIST® (1DAM) lenses in ball sports players.

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.

This study will serve to evaluate and compare the performance of two new lenses to a marketed lens.

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.

This study seeks to evaluate the impact of wearing a new daily disposable soft contact lens on the neophyte population.

Evaluate the short-term corneal response of oxygen deprivation when using toric contact lenses. The response will be noted by endothelial bleb formation in both open eye and closed eye state.

The purpose of this study is to evaluate and compare the clinical performance of two toric contact lenses amongst 110 subjects, 2-week, single masked (subject), daily wear, randomized, bilateral, crossover study; 4 weeks duration. Hypotheses include equal or better performance of the test lens over the control lenses for comfort, vision, and toric fit characteristics as well as corneal integrity

The purpose of this study is to assess the clinical performance of two reusable silicone hydrogel contact lenses when worn on a daily wear basis.

The purpose of this study is to compare the clinical performance of PRECISION1 contact lenses with Biotrue contact lenses.

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.
