ABSTRACT
PURPOSE:
To compare ocular higher order aberrations measured by two different aberrometers in a sample of normal eyes.METHODS:
We included 41 normal eyes of Koreans in this study. Ocular aberration data were obtained through three measurements per eye using Zywave and OPD-Scan devices. Spherical equivalent and higher order aberrations calculated in the central 6 mm zone and expressed as root mean square (RMS) values were analyzed.RESULTS:
A comparison of measurements between the Zywave and OPD-Scan devices demonstrated no statistically significant differences in the RMS values of total higher order aberration (p=0.11), but significant differences were detected in the RMS values of total spherical aberration, total coma and total trefoil (p<0.01).CONCLUSIONS:
The two different aberrometers that we tested are suitable for taking repeated measurements and are internally consistent, but not interchangeable.
