This purpose of this study is to compare the clinical performance and subjective acceptance of two different daily disposable limbal ring lenses.
This is a subject-masked, dispensing study designed to evaluate the clinical performance and subjective acceptance when comparing two different daily disposable limbal ring lenses. Limbal ring lenses, which as well as correcting vision, have a colored ring which enhance the wearer's iris and are particularly popular in East Asian countries.
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Crossover Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment

To evaluate and compare the performance of a new contact lens to a marketed contact lens.
The purpose of this study is to evaluate the effect of a multi-focal contact lens on symptomatic patients.
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.
Single-visit, unmasked, non-dispensing study where subjects will wear three different lenses bilaterally in one visit, each lens being worn for approximately 30-60 minutes. Subjects will c...
Randomized, controlled, multisite, subject-and observer-masked, 3-arm parallel group clinical trial of 36-month duration to evaluate the safety and efficacy of a novel spectacle lens desig...
To discuss the impact of intraocular lens-(IOL)-power, IOL-thickness, IOL-shape, corneal power and effective lens position (ELP) on the distance between the anterior IOL vertex (ALP) of a thick IOL an...
Epidemiological evidence regarding the radiosensitivity of the lens of the eye and radiation cataract development has led to changes in the EU Basic Safety Standards for protection of the lens against...
The formulas are derived for calculation of the third-order aberration (Seidel) coefficients for a thick spherical lens in air with a given value of its focal length and for an object at infinity in t...
The aim of this study was to analyze the bacterial and fungal microbiota found in contact lens cases among two groups of patients to correlate the data on the habits of contact lens users and to evalu...
Glucocorticoid (GC) has been widely used in clinic. However, the effect of GC on normal and myopic development of eyes is still unknown. In this study, 3-week-old guinea pigs were randomly divided int...
Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place.
The portion of the crystalline lens surrounding the nucleus and bound anteriorly by the epithelium and posteriorly by the capsule. It contains lens fibers and amorphous, intercellular substance.
Incomplete rupture of the zonule with the displaced lens remaining behind the pupil. In dislocation, or complete rupture, the lens is displaced forward into the anterior chamber or backward into the vitreous body. When congenital, this condition is known as ECTOPIA LENTIS.
A type of crystallin that has been found in the lens (LENS, CRYSTALLINE) of certain species of VERTEBRATES. They are inactivated form of PHOSPHOPYRUVATE HYDRATASE.
A type of crystallin that has been found in the lens (LENS, CRYSTALLINE) of certain species of MOLLUSCA such as SQUID and OCTOPUS. It is an inactivated form of aldehyde dehydrogenase.
