The primary objective of this trial is to validate the improvements made to the OK inversion indicator. Visibility on eye and on finger will be assessed by the subjects
One month dispensing study comparing the clinical performance of the comfilcon A sphere lenses compared to comfilcon A asphere lenses.
The aim of this study is to determine the clinical performance of comfilcon A in comparison to senofilcon C.
The aim of this study is to compare the subjective performance of the comfilcon A contact lens against lotrafilcon B contact lens after 4 weeks of reusable lens wear.
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).
To test the hypothesis that genes known to cause clinical syndromes featuring myopia also harbor polymorphisms contributing to nonsyndromic refractive errors.
To assess prevalence and associated factors of myopia and high myopia in schoolchildren in Greater Beijing.
To evaluate the incidence and progression of myopia and factors associated with progression of myopia in school going children in Delhi.
The increased prevalence of myopia in the United States and other regions of the world, and the sight-threatening problems associated with higher levels of myopia have led to great interest in researc...
Posterior scleral remodeling accompanies myopia. In guinea pigs developing myopia, the region around the optic nerve (peripapillary zone, PPZ) rapidly expands followed by inhibition in eye size in the...
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.
