Comparison of Fourier-Domain and Time-Domain Optical Coherence Tomography in the Measurement of Thinnest Corneal Thickness in Keratoconus

Table 2

Analysis of intraobserver repeatability of each OCT for normal and keratoconic eyes.

	Normal eyes		Keratoconus
	RTVue-OCT	Visante-OCT	RTVue-OCT	Visante-OCT
	1.23	1.76	5.17	4.65
	0.2%	0.3%	1.2%	1.1%
ICC (95% LoA)	0.994 (0.991–0.997)	0.989 (0.983–0.993)	0.984 (0.976–0.989)	0.987 (0.981–0.991)
