Objective measurement of refractive errors: Comparison of plusoptix s08 with a standard autorefractometer

Abstract

Objective: Comparison of Plusoptix S08 with a standart autorefractometer (Topcon RM 8000B) in children and adults. Methods: 220 eyes of 110 children, with a mean age of 8.06 &plusmn; 2.89 years old were examined to compare non-cycloplegic 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 &plusmn; 13.36 years old were examined to compare non-cycloplegic refractive mea&shy;surements provided by Plusoptix S08 and Topcon RM 8000B autorefractometer. All measurements were repeat&shy;ed three times. Median sphere, cylinder, spherical equiva&shy;lent and cylindrical axes as Jackson cross cylinder power measurements (J0 and J45) were compared statistically. Results: The median differences in spheres, cylinders, spherical equivalents, J0 and J45 powers were &ndash;0.25 D (P< 0.001), &ndash;0.25 D (P< 0.001), &ndash;0.25 D (P< 0.001), &ndash;0.02 (P= 0.038), 0.00 (P= 0.395), in children, respec&shy;tively. These values were 0.50 (P

Objektif refraksiyon kusuru ölçümü: Plusoptix s08 ile standart bir otorefraktometrenin karşılaştırılması

Abstract

Amaç: Çocuklarda ve erişkinlerdeki refraksiyon kusuru ölçümünde, Plusoptix S08 ile standart bir oto refraktomet&shy;re (Topcon RM 8000B) ölçümlerinin karşılaştırılması. Yöntemler: Yaş ortalaması 8.06 &plusmn; 2.89 yıl olan 110 çocu&shy;ğun 220 gözü Plusoptix S08 ile sikloplejisiz olarak, Top&shy;con RM-8000B otorefraktometresiyle sikloplejili olarak ölçüldü. Elde edilen değerler karşılaştırıldı. Ayrıca, yaş ortalaması 33,3 &plusmn; 13,4 olan 127 yetişkinin 254 gözü, Plu&shy;soptix S08 ve Topcon RM 8000B otorefraktometre ile sik&shy;loplejisiz olarak ölçülerek, bu ölçümlerin karşılaştırması yapıldı. Tüm ölçümler üç kez tekrarlandı. Ortalama sferik, silindirik, sferik ekivalan ve silindirik aks değerleri istatis&shy;tiksel olarak karşılaştırıldı. Bulgular: Ortalama sferik, silindirik, sferik ekivalan, J0 ve J45 güçleri çocuklarda sırasıyla: &ndash;0.25 D (p< 0.001), &ndash;0.25 D (p< 0.001), &ndash;0.25 D (p< 0.001), &ndash;0.02 (p= 0.038), 0.00 (p= 0.395) bulundu. Erişkinlerde ise 0.50 (p
