Purpose
The purpose of this study was to compare and evaluate the correlation and consistency in measuring corneal thickness of healthy myopic eyes using Pentacam, Sirius, and IOLMaster700.
Setting
Harbin Bright Eye Hospital, Harbin, Heilongjiang, China
Methods
This study was conducted on 269 right eyes of 134 males and 135 females.
The central corneal thickness was measured using Pentacam, Sirius, and IOLMaster 700.
Measurement differences between devices were analyzed using SPSS statistical techniques. To evaluate the agreement was using the Bland-Altman analysis.
Results
The mean age was 24.87±6.37 (17~47) years. The mean CCT by Pentacam, Sirius, and IOLMaster700 was 541.63±31.67μm, 541.74±33.36μm, and 548.90±34.19μm, which were statistically significant (p＜0.05). The Pearson’s correlation coefficients by Pentacam and Sirius, Pentacam and IOLMaster700, as well as Sirius and IOLMaster700 were 0.972, 0.966, and 0.962, respectively (p＜0.001). The 95% limits of agreement were 2.67 to 8.44µm between Pentacam and Sirius, 1.91 to 8.35µm between Pentacam and IOLMaster700, -3.76 to 2.95µm between Sirius and IOLMaster700.
Conclusions
The CCT of healthy myopic eyes measured by three different devices is significantly correlation, but the CCT measured by different devices is statistically different. Therefore, CCT evaluation and follow-up should be measured by the same device in practical clinical.
