Comparison between a New Optical Biometry Device and an Anterior Segment Optical Coherence Tomographer for Measuring Central Corneal Thickness and Anterior Chamber Depth

Table 1

Comparison of central corneal thickness (CCT), anterior chamber depth (ACD), and aqueous depth (AD) measured by the AL-Scan partial coherence interferometry and Visante optical coherence tomography.

Device pairings	Mean difference ± SD	value	95% LoA
CCT (m)	2.45 ± 6.07	0.002	−9.44 to 14.35
ACD (mm)	−0.01 ± 0.07	0.119	−0.15 to 0.12
AD (mm)	−0.02 ± 0.07	0.077	−0.15 to 0.12

SD: standard deviation.
