Active clinical trials for "Refractive Errors"

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 clinical study is to assess the clinical performance of an investigational toric soft contact lens compared to a commercially available toric contact lens in a crossover dispense trial when worn in a daily wear modality for 30 days, each study lens type.

The purpose of this study is to evaluate the pre lens tear film characteristics of DAILIES® Aqua Comfort Plus® Multifocal (DACP MF) and Toric (DACP Toric) compared to DAILIES® Aqua Comfort Plus® Sphere (DACP) daily disposable contact lenses over 12 hours of lens wear.

Comparison of different contact lens materials.

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.

The purpose of this study is to obtain on-eye performance data to inform contact lens product development and to further evaluate product performance in the intended population.

The study will compare the short-term clinical performance and wearer and practitioner acceptability in a pilot study of a new-to-market spherical silicone hydrogel daily disposable soft contact lens (SiHyDD) to three (3) benchmark soft daily disposable lenses (DD) and, subsequently, of a new-to-market hydrogel spherical daily disposable (HydDD) soft contact lens to three (3) other hydrogel daily disposable lenses. . The primary outcome variables for this study are subjective comfort and lens preference.

The purpose of this clinical study is to evaluate the on-eye performance of an investigational soft contact lens compared to a commercially available soft contact lens following 1 night of extended wear.

The purpose of this study is to assess the clinical performance of an investigational, coated silicone hydrogel contact lens over approximately 30 days of daily wear.

Three-month, open-label, bilateral, parallel group, randomized, daily wear contact lens dispensing study.
