Conceptualization, With subjective refraction, the range of spherical refractive error was -6.50 Diopters (a unit of measurement of the optical power of a lens or curved mirror, which is equal to the reciprocal of the focal length measured in meters, denoted as D) to +6.00 D, with the mean +0.18 D and median +0.50 D. The range of cylinder error was -5.00 to +0.98 D, with the mean -0.58 D and median -0.50 D. The Bland-Altman comparison of Subjective Refraction with Retinomax (Fig 1) revealed the limits of agreement (reference range for difference): -3.076 D to 4.447 D.
