Purpose:

To compare cycloplegic autorefraction with non-cycloplegic subjective refraction across all age and refractive error groups

Methods:

In a cross-sectional study with random stratified cluster sampling, 160 clusters were chosen from various districts proportionate to the population of each district in Tehran. Following retinoscopy and autorefraction, all participants had a subjective refraction.

Results:

Based on cycloplegic and subjective refraction, mean spherical equivalent was +0.31 ±1.80 and -0.32 ±1.61 diopter (D), respectively (p<0.001). The largest difference between these two types of refraction was seen in the 5-10 year age group (1.11 ±0.60 D) and the smallest difference was in the over 70 age group (0.34 ±0.45D). We found that female gender, older age, higher education and cycloplegic spherical equivalent significantly correlated with lower inter-method differences. The smallest difference between these two types of refraction was seen in myopic subjects (0.19D) and the largest difference was in hyperopes (0.96D).

Conclusion:

Despite a strong correlation, results of cycloplegic and subjective refraction were different in all age groups. The difference decreases with age, and is greater in men than women
