Evaluation of Central Corneal Thickness Using Corneal Dynamic Scheimpflug Analyzer Corvis ST and Comparison with Pentacam Rotating Scheimpflug System and Ultrasound Pachymetry in Normal Eyes

Table 3

Comparison of the central corneal thickness readings obtained using the corneal dynamic Scheimpflug analyzer Corvis ST, Pentacam rotating Scheimpflug system, and ultrasound pachymetry.

Device pairings	Mean difference (μm) ± SD	95% LoA (μm)	value
Corvis-Pentacam	−3.2 ± 6.5	−15.8 to 9.5	<0.001
Corvis-USP	−7.8 ± 10.3	−27.9 to 12.3	<0.001

USP = ultrasound pachymetry, SD = standard deviation.
