Objective refraction: comparison of retinoscopy and automated techniques.
The Canon Autoref R-1 and Dioptron II automated objective refractors and static distance retinoscopy were performed in a clinical setting on 75 subjects. Each technique was performed by a different examiner and the findings were compared by statistical analysis. The results were comparable with all three techniques. These data are discussed in light of their clinical significance.
