(1)	ACD, mm	0.853	0.853	66.019 (59.121 to 72.918)	<
(2)	ACW-H, mm	0.037	0.890	22.394 (17.764 to 27.024)	<
(3)	LV, mm	0.016	0.906	−23.276 (−31.707 to −14.845)	<
(4)	AL, mm	0.003	0.909	2.707 (−0.674 to 4.739)	<
(5)	ACW-V, mm	0.003	0.912	4.286 (1.284 to 8.58)
(6)	IV, mm	0.002	0.914	−0.546 (−0.828 to −0.263)

< 0.05.
CI = confidence interval, ACD = anterior chamber depth, ACW-H = anterior chamber width measured in the horizontal direction, LV = lens vault, AL = axial length, ACW-V = anterior chamber width measured in the vertical direction, and IV = iris volume.
