Reproducibility of Central Corneal Thickness Measurements in Normal Eyes Using the Zeiss Cirrus 5000 HD-OCT and Pentacam HR

Table 1: Mean ± SD Values for CCT Measurements in Healthy Eyes Obtained by the Pentacam HR and Cirrus 5000 HD-OCT.

Parameter	Cirrus HD cornea	Cirrus AC scan	Cirrus Pachymetry scan	Pentacam HR
CCT (µm)	537.87 ± 26.82	545.35 ± 31.02	532.04 ± 29.82	545.51 ± 30.71

Significant linear positive correlations were observed between the Cirrus HD-OCT and Pentacam HR CCT measurements (Pearson’s correlation, r = 0.98, p-value< 0.0001) (Table 2).
