Purpose:
|
The purpose of this study was to compare keratometry measurements from the wavelight topolyzer vario and the Javal Manual keratometer.
|
|
Methods:
|
Keratometry measurements in the steep (Ks) and flat (Kf) meridians were taken with the Javal Manual keratometer (Javal Schiotz type; Haag-Streit AG, Koeniz,Switzerland) and wavelight topolyzer vario ( Wavelight, Germany)in myopic virgin eyes. The 95% limits of agreement (LOAs) were reported to evaluate the agreement between devices.
|
|
Results:
|
The mean K readings of wavelight topolyzer vario and Javal Manual keratometer were 43.89/43.71 diopter (D), 44.01/43.92 D, respectively. Correlation coefficients for the CASIA AS-OCT and Javal Manual keratometer in measuring flat K and steep K were r=0.918 and r=0.921, respectively (p<0.001).
|
|
Conclusion:
|
The wavelight topolyzer vario provided reliable K
measurements in clinical practice in comparison with Javal Manual keratometry and seem to be interchangeable.
