Comparison of Anterior Ocular Biometric Measurements Using Swept-Source and Time-Domain Optical Coherence Tomography

Table 2

The mean difference, paired t test ( value), and 95% LoA for differences between the SS-OCT and TD-OCT devices.

Device pairings	Mean ± SD	value	95% LoA
CCT (μm)	4.55 ± 2.62	<0.001	−0.59 to 9.69
AQD (mm)	0.01 ± 0.05	0.111	−0.10 to 0.12
ACD (mm)	0.02 ± 0.05	0.022	−0.09 to 0.12

SD = standard deviation; CCT = central corneal thickness; AQD = aqueous depth; ACD = anterior chamber depth.
