This study is intended to show that the investigational contact lens is clinically equivalent to a currently approved contact lens, when worn as single-use on a daily basis.
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Treatment

This study aims to compare the clinical performance and subjective acceptance of the narafilcon A lens with the stenfilcon A lens when used on a daily wear, daily disposable basis.
This study is a multi-site, group sequential, adaptive, randomized, double-masked, 2×2 crossover design, 1-week dispensing study. Subjects will wear bilaterally both Test and Control lens...
The purpose of this study is to evaluate the performance of the nelfilcon A lens compared to a competitive daily disposable lens, narafilcon A, in a population of neophytes (new wearers).
The trial intends to compare the extent to which symptoms improve in symptomatic daily wear contact lens wearers who replace their lenses at intervals of 2 weeks or monthly when fit with D...
Clinical evaluation of stenfilcon A compared with narafilcon A and delefilcon A This is a total 120 subject, randomized, open label, bilateral wear, two week crossover study (each lens fo...
During the past 30 years, the prevalence rate of myopia has been increased dramatically. Myopia has become one of the leading causes of vision loss in some countries, whereas the mechanism of the main...
The burden associated with the rising prevalence of myopia and high myopia, and the associated vision impairment and sight-threatening complications, has triggered the need to evaluate strategies to c...
The purpose of this study was to determine the prevalence of myopia in a population of children in Sweden. Retrospective analysis of children in a region in Sweden referred to eye care from the nation...
In the nineteenth century, the prevalence of myopia began to rise, and Cohn stressed the role of education. Later, based on twin studies, Sorsby argued that refraction was almost totally genetically d...
Experimental myopia in animal models suggests that bright light can influence refractive error and prevent myopia. Additionally, animal research indicates activation of rod pathways and circadian rhyt...
Excessive axial myopia associated with complications (especially posterior staphyloma and CHOROIDAL NEOVASCULARIZATION) that can lead to BLINDNESS.
Plastic surgery of the SCLERA. This procedure is used frequently to prevent blindness and poor vision in patients, especially children, with MYOPIA.
A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.
Detachment of the corpus vitreum (VITREOUS BODY) from its normal attachments, especially the retina, due to shrinkage from degenerative or inflammatory conditions, trauma, myopia, or senility.
A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.
