“…One study [41] report that noncycloplegic measurements of equivalent spheres were consistently more negative or less positive than those after cyclopegia. The use of non-cyclopegic auto-refraction is more accurate in the detection of astigmatism and abnormally high levels of hyperopia.…”

“…3,12,16 In the literature, we have seen few studies designed to compare the measurements Plusoptix S08 and an autorefractometer in children and adults. [13][14][15][16][17][18][19][20][21] Aim of the study was to evaluate if Plusoptix S08 could be considered as an autorefractometer or not.…”

“…Cycloplegia was considered complete if the pupil dilated 6 mm and pupillary constriction was absent. 15 17 The normality of our data was tested with Shapiro-Wilks test and because the normality assumption was not satisfied Wilcoxon signed rank test was used for the comparision of Plusoptix S08 and Topcon RM 8000B measurements. The significance level (p value) is chosen to be less than 0.05.…”

, Cemil Çolak 4ÖZET Amaç: Çocuklarda ve erişkinlerdeki refraksiyon kusuru ölçümünde, Plusoptix S08 ile standart bir oto refraktometre (Topcon RM 8000B) ölçümlerinin karşılaştırılması.Yöntemler: Yaş ortalaması 8.06 ± 2.89 yıl olan 110 çocu-ğun 220 gözü Plusoptix S08 ile sikloplejisiz olarak, Topcon RM-8000B otorefraktometresiyle sikloplejili olarak ölçüldü. Elde edilen değerler karşılaştırıldı. Ayrıca, yaş ortalaması 33,3 ± 13,4 olan 127 yetişkinin 254 gözü, Plusoptix S08 ve Topcon RM 8000B otorefraktometre ile sikloplejisiz olarak ölçülerek, bu ölçümlerin karşılaştırması yapıldı. Tüm ölçümler üç kez tekrarlandı. Ortalama sferik, silindirik, sferik ekivalan ve silindirik aks değerleri istatistiksel olarak karşılaştırıldı. Methods: 220 eyes of 110 children, with a mean age of 8.06 ± 2.89 years old were examined to compare noncycloplegic measurements provided by Plusoptix S08 and cycloplegic measurements provided by Topcon RM-8000B autorefractometer. In addition, 254 eyes of 127 adults, with a mean age of 33.3 ± 13.36 years old were examined to compare non-cycloplegic refractive measurements provided by Plusoptix S08 and Topcon RM 8000B autorefractometer. All measurements were repeated three times. Median sphere, cylinder, spherical equivalent and cylindrical axes as Jackson cross cylinder power measurements (J0 and J45) were compared statistically. Results Conclusion:Plusoptix S08 has a myopic misspelled according to Topcon-RM8000B autorefractometer in children. However, measurements provided with Plusoptix S08 were more hyperopic than those with Topcon RM-8000B autorefractometer in adults. J Clin Exp Invest 2013; 4 (1): 40-46

“…This method also compares the spherical equivalent and the overall blurring strength of the refractive error denoted by overall blur strength, which incorporates both the astigmatism and the spherical equivalence. This vector analysis was also used by Zhao and colleagues 11 in their population-based study comparing the accuracy of noncycloplegic and cycloplegic autorefraction in school-aged children.…”
