Objective refraction: comparison of retinoscopy and automated techniques
American Journal of Optometry and Physiological Optics
|March 1, 1984
Summary
Automated refractors (Canon Autoref R-1, Dioptron II) and static retinoscopy showed comparable results in a clinical study of 75 subjects. These objective refraction methods offer similar clinical significance for eye examinations.
Area of Science:
- Ophthalmology
- Optometry
- Vision Science
Background:
- Accurate refractive error assessment is crucial for diagnosing and managing visual impairments.
- Automated refractors and retinoscopy are common methods for objective refraction.
Purpose of the Study:
- To compare the clinical comparability of two automated objective refractors (Canon Autoref R-1, Dioptron II) against static distance retinoscopy.
- To evaluate the clinical significance of findings from these objective refraction techniques.
Main Methods:
- Objective refraction was performed on 75 subjects using Canon Autoref R-1, Dioptron II, and static distance retinoscopy.
- Each technique was administered by a separate examiner.
- Findings were statistically analyzed for comparison.
Main Results:
- The results obtained from the Canon Autoref R-1, Dioptron II, and static distance retinoscopy were found to be comparable.
- Statistical analysis indicated no significant differences between the three objective refraction methods.
Conclusions:
- Automated objective refractors (Canon Autoref R-1, Dioptron II) provide results comparable to static distance retinoscopy.
- These findings support the clinical utility and significance of all three methods in routine eye examinations.
