    The Dioptron automatic refractor shows better consistency than subjective refraction. However, visual acuity results should be confirmed with subjective refraction, especially for the Dioptron.

    Area of Science:

    • Ophthalmology
    • Optometry
    • Vision Science

    Background:

    • Accurate refractive error assessment is crucial for optimal vision correction.
    • Automatic refractors offer potential for faster and more consistent measurements compared to subjective methods.

    Purpose of the Study:

    • To evaluate the consistency of the "Dioptron" automatic refractor.
    • To compare the refractive values obtained by the "Dioptron" with subjective refraction.
    • To assess the "Dioptron"'s performance in a pediatric population.

    Main Methods:

    • Repeated measurements were taken on one subject using the "Dioptron" automatic refractor.
    • Visual acuity was compared between "Dioptron" refraction and subjective refraction in 140 eyes.
    • The "Dioptron" was also tested on 15 children aged 5-12 years.

    Main Results:

    • The "Dioptron" demonstrated significantly better consistency than subjective refraction.
    • In approximately 20% of eyes, "Dioptron" refraction yielded lower visual acuity compared to subjective refraction.
    • The apparatus was used successfully in children aged 5-12 without reported issues.

    Conclusions:

    • The "Dioptron" automatic refractor offers high consistency in refractive measurements.
    • Subjective refraction remains essential to confirm "Dioptron" results, particularly when visual acuity is lower.
    • The "Dioptron" appears to be a viable tool for pediatric eye examinations.
