DOI: 10.1016/j.ajo.2019.07.001
Abstract: PURPOSE Wavelength dependence of diffractive intraocular lenses (IOLs) was recognized in vitro but not yet assessed in vivo. By examining pseudophakic patients who had extended-depth-of-focus diffractive implants, we clinically measured this spectral effect on their… read more here.

DOI: 10.1016/j.exger.2019.01.009
Abstract: Background Hypertension is established to cause vascular end‐organ damage. Other forms of dysregulated blood pressure (BP) behaviour, such as orthostatic hypotension have also been associated with cardiovascular (CV) events. The eye is potentially vulnerable to… read more here.

Sign Up to like & getrecommendations! Published in 2017 at "Scientific Reports"
DOI: 10.1038/srep46706
Abstract: The contrast sensitivity function (CSF) relates the visibility of a spatial pattern to both its size and contrast, and is therefore a more comprehensive assessment of visual function than acuity, which only determines the smallest… read more here.
