RESUMEN

Currently, three different automated objective refractors are available commercially and are being used throughout the world. The most recently developed objective refractor. Dioptron, is an electro-optical instrument for measuring the refractive state of the eyes. The computer in this instrument takes the measurements and calculates automatically his objective refraction in term of sphere, cylinder and axis corrected for 12mm vertex distance. The motivation for this investigation was the need for a quantitative evaluation of Dioptron to determine how it may be utilized most effectively in clinical practice. The results in this study are based on comparisions of differences between Dioptron and streak retinoscopy which were examined the random samples of 800 eyes. In this analysis, authors found that the Dioptron proved to be more accurate in the cylinder and axis and equivalent in sphere findings when compared to streak retinoscopy although Dioptron could not replace physician's judgement.
