Purpose: To compare the refraction values obtained with Plusoptix A09 photorefractometer and Topcon autorefractometer in adults.
Materials and Methods: 230 eyes of 115 patients who had no eye disease other than refractive error were included in the study. Refraction measurements were made with Plusoptix A09 photorefractometer and Topcon KR-8100P autorefractometer devices. Measurements were taken 3 times and the averages were recorded. Median spherical, cylindrical, spherical equivalent and cylindrical axis measurements obtained with both devices were statistically compared. Interdevice compatibility was evaluated with intraclass correlation coefficient (ICC) and Spearman correlation analysis.
Results: The median age of 115 patients included in the study was 37 years (range, 20-67), and 50 (43.5%) were female and 65 (56.5%) were male. Median spherical value obtained with Plusoptix A09 photorefractometer 0.50 D (range, -4.00-(3.25)), median cylindrical value -0.50 D (range, -2.00-(0.00)), spherical equivalent median 0.38 D (range, -4.00- (3.00)), the J0 power median was 0 (range, -1.00-(1.00)), and the J45 power median was 0 (range, -0.49-(0.37)). The median of the spherical value obtained by autorefractometer is 0.0 D (range, -3.75-(2.00)), the median of the cylindrical value is -0.50 D (range, -2.00-(0)), the median of the spherical equivalent is -0.25 D (range, -3.75- (1.75)), the J0 power median was 0 (range, -0.87-(0.98)), and the J45 power median was 0 (range, -0.59-(0.50)). There was a significant difference between spherical, cylindrical and spherical equivalent measurements between devices. There was no significant difference between J0 and J45 measurements.
Conclusion: Besides being used in childhood, Plusoptix A09 photorefractometer can also be used as a fast and easy refraction measurement method, especially in physically or mentally handicapped adults with adjustment problems.
