Active clinical trials for "Refractive Errors"

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 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 visual acuity between two daily disposable contact lenses.

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.

The primary purpose of this study is to demonstrate noninferiority in the visual acuity at distance when wearing PRECISION1™ for Astigmatism (P1fA) soft contact lenses compared to another commercially available, soft toric contact lens, MyDay® toric (MDT).

Approximately 30 soft toric contact lens adapted subjects will be enrolled in this feasibility, bilateral, randomized, double masked (subject and investigator masked), repeated measures insertion study. All subjects will be seen for a Screening/Dispensing Visit at which informed consent will be obtained and eligibility will be assessed. If subjects satisfy all eligibility criteria and none of the exclusion criteria, subjects will have study lenses inserted in random, successive order according to unique randomization schedules that will be provided to each Investigator.

The purpose of this study is to compare the clinical performance of LID018869 soft contact with ACUVUE® OASYS with HYDRACLEAR® PLUS (AOHP) soft contact lenses over 30 days of daily wear.

The purpose of this study is to evaluate the functional vision of 2 daily disposable silicone hydrogel contact lenses using Time Controlled Visual Acuity (TCVA) measurements at high luminance and high contrast after 10+/-3 days of wear post 3 hour exposure to a reduced humidity environment.

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.

Dispensing Study for the Phenacite Project. The investigational test lens was not the final optical design and the study was not used for design validation.
