- Abstract
Objectives: This study was conducted to compare refractive error measurements recorded using the Nidek HandyRef-K handheld autorefractometer (HDY; Nidek Co. Ltd., Tokyo, Japan), Plusoptix A09 photorefractor (PO; Plusoptix GmbH, Nuremberg, Germany), Retinomax K-plus 3 (RTX; Right Mfg. Co. Ltd., Tokyo, Japan), and a table-mounted autorefractometer/keratometer (TTR; URK 800, Unicos Co. Ltd., Daejeon, Republic of Korea). Methods: Patients aged =18 years underwent measurement of refraction without cycloplegia using 4 devices and the spherical power (SP), cylindrical power (CP), and spherical equivalent (SE) values were analyzed and compared. Results: A total of 181 eyes of 181 patients were enrolled in the study. The mean age of the patients was 33.08±0.95 years (range: 18-79 years). There was a significantly significant difference in the SP, CP, and SE values determined by the devices (p<0.001). The SP and SE values of the RTX and the HDY were similar, while the other device results were different (Wilcoxon signed-rank test, p=0.004). The CP values of the PO and the TTR, the HDY and the TTR were also comparable. Conclusion: The HDY, RTX, and the PO are suitable for screening in clinical practice, but the findings strongly suggest that they should be used with caution.
