Predictive Factors of the Standard Cross-linking Outcomes in Adult Keratoconus: One-Year Follow-Up

Table 2

The changes in mean different parameters between the baseline and at the end of one-year post-CXL and their values in the entire study.

Parameters in (136 eyes)	Baseline mean ± SD	One year mean ± SD	value
UCVA (logMAR)	0.74 ± 0.10	0.52 ± .01	<0.001
BCVA (logMAR)	0.38 ± 0.02	0.24 ± 0.12	<0.001
K max (D)	49.16 ± 0.25	47.15 ± 0.25	0.002
CCT (μ)	466.98 ± 6.21	455.47 ± 4.52	<0.001
Thinnest location (μ)	454.76 ± 5.11	421.37 ± 3.24	<0.001

CXL: crosslinking; SD: standard deviation; UCVA: uncorrected visual acuity; BCVA: best-corrected visual acuity; logMAR: logarithm of the minimum angle of resolution; K max: maximum K reading; CCT: central corneal thickness; test used: paired sample t-test; significant at the value <0.05.
