Refractive surgery, a subfield of ophthalmology, is defined as the surgical correction of refractive errors of the human eye. It has become a highly specialized area in the last few years. Ophthalmic ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

This paper introduces a novel focusing method Refraction Topography (RT) for wide-angle refraction measurement. The agreement of the test results obtained using RT is evaluated against simulation ...

Uncorrected refractive error (URE) is one of the leading causes of childhood vision impairment. Increasing effective refractive error coverage (e-REC) is one of the ...
