Effective refractive error coverage and quality gaps in Bhutan: evidence from rapid assessment of refractive error [PDF]
BMC Public HealthBackground Uncorrected refractive errors (URE) and presbyopia are leading causes of visual impairment (VI) globally. Bhutan currently lacks population-based data on adult refractive error, hindering efforts to meet WHO’s 2030 targets for effective ...

Refractive error maps: A predictive tool for refractive error progression [PDF]
Ophthalmic and Physiological OpticsAbstractPurposeTo investigate the influence of axial length on different ocular parameters and create a predictive tool for refractive error progression.MethodsTwo eye models were used to simulate refractive errors, namely the Liou–Brennan and the Goncharov–Dainty. Both models were simulated using Zemax OpticStudio.

Stereoacuity after photorefractive keratectomy in myopia
Journal of Current Ophthalmology, 2016 Purpose: Stereopsis, as a part of visual function, is the ability of differentiating between the two eyes' views (binocular disparity), due to the eyes' different positions.

Association between Refractive Error and Decreasing Visus in Pregnant Women [PDF]
, 2018 Background: Refractive error is a problem with focusing light accurately onto the retina due to the shape of the eye. The most common types of refractive error are near-sightedness, far-sightedness, astigmatism, and presbyopia.
