A thorough ophthalmic examination of a child must include a refraction and this is often done with cycloplegia. In our study, we aim to determine at which age group a non-cycloplegic refr...
The study is used to verify the accuracy and repeatability of Smart Vision Labs Refractor in a pediatric population (between 5 and 16 years of age).
The assessment of the refractive state of the eye is a fundamental and important part of ophthalmic and optometric clinical practice. The development of an unsupervised online subjective r...
The purpose of the study is to compare the final glasses prescription based on refraction obtained with SVOne device to the final prescription obtained via subjective manifest refraction.
The purpose of prospective cohort study is to describe the developmental profile of refraction change in a large cohort of Chinese CC patients. The decisive factors to the range of myopic ...
Hyperopic shifts in refraction have been consistently reported in adults over 40, followed by myopic shifts after age 70. Although potential factors underlying these changes in refraction in older adu...
To determine ocular refraction, corneal thickness, corneal radius, corneal power, corneal astigmatism and intraocular pressure in patients before and immediately after repeated hyperbaric oxygen (HBO2...
To evaluate long-term ocular surface clinical signs and symptoms response to therapy in patients with chronic ocular GVHD.
Refractive errors, myopia and hyperopia are a common visual disorders greatly affecting older individuals. Refraction is determined by genetic factors but only a small percentages of its variation has...
To evaluate the impact of differences in nearwork and time spent outdoors on difference in refraction in monozygotic (MZ) twins.
Refraction of LIGHT effected by the media of the EYE.
Ocular manifestations secondary to various NEOPLASMS in which antibodies to antigens of the primary tumor cross-react with ocular antigens. This autoimmune response often leads to visual loss and other ocular dysfunctions.
The dioptric adjustment of the EYE (to attain maximal sharpness of retinal imagery for an object of regard) referring to the ability, to the mechanism, or to the process. Ocular accommodation is the effecting of refractive changes by changes in the shape of the CRYSTALLINE LENS. Loosely, it refers to ocular adjustments for VISION, OCULAR at various distances.

A physical property showing different values in relation to the direction in or along which the measurement is made. The physical property may be with regard to thermal or electric conductivity or light refraction. In crystallography, it describes crystals whose index of refraction varies with the direction of the incident light. It is also called acolotropy and colotropy. The opposite of anisotropy is isotropy wherein the same values characterize the object when measured along axes in all directions.
Ocular disorders attendant upon non-ocular disease or injury.
