The aim of this non-dispensing fitting study is to evaluate the subjective comfort, lens handling, lens fitting characteristics and visual acuity of different hydrogel lens designs versus silicone hydrogel lenses
This is a 60-subject, double masked, randomized, contra lateral, non-dispensing fitting trial comparing different lens materials (hydrogel vs silicone hydrogel). It is anticipated that this study will involve 2 visits, for each lens pair, as follows: Visits: V1 (lens dispensing), V2 (1 hour post lens settling). Each subject will be randomized to wear the test and control lenses in a series of three short fitting comparisons.
Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator)

The purpose of this study is to evaluate the clinical performance and subject's preference out of three LRE (Limbal Ring Enhancing) lens types: enfilcon A (Johnson&Johnson), methafilcon A ...
The objective of the study is to determine if habitual or adapted contact lens wearers of Omafilcon A can be confidently refit into Somofilcon A lenses and be successful after one week of ...
This study aims to compare the clinical performance of the somfilcon A, nelfilcon A II 2 and omafilcon A II 2 daily disposable contact lenses.
Open label, 1-week daily disposable, dispensing study

Parental myopia is an important risk factor for preschool myopia in Asian children. Further investigation of the association between parental myopia and early-onset myopia risk in other racial/ethnic ...
Myopia is one of the leading ocular disorders causing visual impairment worldwide, with the prevalence increasing rapidly. It's a significant global public health concern in 21st century. Myopia, part...
Myopia is a global problem that is increasing at an epidemic rate in the world. Although the refractive error can be corrected easily, myopes, particularly those with high myopia, are susceptible to p...

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.
