Active clinical trials for "Refractive Errors"

The primary objective of thes study is to confirm that the ocular response to the Test lenses are similar to those of the Control lenses when used in a 1 week planned replacement, daily wear modality over a 1-month period.

Randomized, double-masked, controlled, 2-arm parallel group, multi-site, 3-month dispensing study of Johnson & Johnson Vision Care, Inc. (JJVCI) Investigational contact lens, compared with a marketed, monthly replacement contact lens. Subjects will wear the JJVCI investigational contact lenses on a daily wear basis.

The purpose of this clinical trial is to determine if interventions within the nursing home to restore vision, or cope with visual loss, in residents with visual impairment result in improvement or less decline in mobility scores, and socialization scores, compared to residents with visual impairment in nursing homes with no such intervention. The investigators hypothesized that nursing home residents with visual loss who receive cataract surgery, or refractive correction, or low vision aids would have have better socialization scores and mobility scores at 6 months and 12 months compared to nursing home residents with visual impairment who are advised to seek services, but have no specific program.

The purpose of this retrospective, Post-Market Clinical Follow-Up (PMCF) study is to assess the long term performance and safety of Air Optix® Night and Day® Aqua (AONDA) contact lenses in a real-world setting when worn as 30 days of continuous wear for vision correction.

This study will test whether the combined treatment of 0.01% atropine and soft bifocal contact lens wear produces slower myopia progression and axial elongation compared to soft bifocal contact lenses alone in children ages 7 to 11 years old.

To evaluate the safety and effectiveness of Aceclidine/Brimonidine (LNZ101) compared with Aceclidine (LNZ100) and vehicle in the treatment of Presbyopia.

The purpose of this study is to evaluate the impact of back surface molded marks (MM) applied to delefilcon A contact lenses as measured by the incidence of ocular discomfort device-related adverse events with DAILIES TOTAL1® Multifocal contact lenses with molded marks (DT1 MF MM) and current DAILIES TOTAL1® Multifocal contact lenses (DT1 MF).

The purpose of this project is to determine the effectiveness of an eyewash osmoprotective lubricant comparing to castor oil containing and non-osmoprotective lubricants in different types of DTS and post refractive surgery patients.

The aim of this study was to compare the effectiveness of two interventions, namely providing free spectacles or only a prescription to students with insufficiently corrected or uncorrected significant refractive errors.
