“…Our results are consistent with data from previous studies 3–5,10,19,22 . We found high repeatability in all visits, with better results occurring with longer post‐surgical times.…”

“…Also, autorefraction is very useful when subjective refraction is not available, for example, after cataract surgery, to monitor the stabilization of the refraction. There are only a few studies about refractive changes or the repeatability and validity of autorefraction immediately after cataract surgery 2,9 ,10 . Therefore, the aims of this study were to (i) evaluate the repeatability of the ARK‐30 (Nidek Co. LTD, Aichi, Japan) handheld autorefractor and (ii) determine the agreement between this instrument and subjective refraction and retinoscopy in patients after uneventful cataract surgery.…”

“…Thirty minutes after the instillation of cyclopentolate HCl 1% pupil dilation was checked for eye drop action efficacy and refractive error was measured using the Shin‐Nippon NVision‐K 5001 open‐field autorefractor (http://www.shin-nippon.jp/products/nvk5001/index.html). The Shin‐Nippon NVision‐K 5001 has been reported to provide a quick, accurate and repeatable measure of refractive error in many studies of refractive error . The open‐field design permits the assessment of refractive error and corneal curvature while the participant views a distant external target.…”

This is the first study to describe the refractive profile of a population of European Caucasian children with ASD compared to a TD population of children. Unlike other neurodevelopmental conditions, there was no increased prevalence of spherical refractive errors in ASD but astigmatic errors were significantly greater in magnitude and prevalence. This highlights the need to examine refractive errors in this population.

“…This instrument has similar technical specifications to that of the Shin‐Nippon SRW‐5000 (Grand Seiko WV‐500). The Shin‐Nippon NVision‐K 5001 autorefractor has been widely used in research studies for measuring accommodation, and both central and peripheral refractive errors …”
