Self evaluating tools based on smartphone devices are public available on the market for each person. The tools are used to estimate the existing refractive error for each eye of a patient...
Blindness and visual impairment severely impact the visual health and life quality of people, particularly the 2.566 million senior citizens aged at 65 and above in Shanghai. The main reas...
The study aims to observe the ocular development and refractive error changes among school children and adolescents
To evaluate and compare the performance of a new contact lens to a marketed contact lens.
This study seeks to evaluate the clinical fitting performance of a new daily disposable contact lens to an existing daily disposable contact lens.
Existing patient-reported outcome instruments in refractive error are paper-based questionnaires. They are not comprehensive and psychometrically robust. This study has identified the content of the r...
An iterative algorithm based on optical path difference (OPD) and ray deflection is proposed to obtain the DT (deuterium-tritium)-layer refractive index and thickness of the ICF (inertial confinement ...
To examine the prevalence of refractive error and some associated factors in Chinese preschool children.
We evaluate how deep learning can be applied to extract novel information such as refractive error from retinal fundus imaging.
Uncorrected refractive error (URE) is a common cause of visual impairment, but its prevalence in groups of older adults who could be pragmatic targets for improving optical correction remains unknown.
Term generally used to describe complaints related to refractive error, ocular muscle imbalance, including pain or aching around the eyes, burning and itchiness of the eyelids, ocular fatigue, and headaches.
A refractive error in which rays of light entering the eye parallel to the optic axis are brought to a focus behind the retina, as a result of the eyeball being too short from front to back. It is also called farsightedness because the near point is more distant than it is in emmetropia with an equal amplitude of accommodation. (Dorland, 27th ed)
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.
Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus.
A procedure to surgically correct REFRACTIVE ERRORS by cutting radial slits into the CORNEA to change its refractive properties.
