Primary Outcomes of Accelerated Epithelium-Off Corneal Cross-Linking in Progressive Keratoconus in Children: A 1-Year Prospective Study

Table 3

Changes in CDVA, UCVA, steepest K, and corneal thickness at 12 months post-ACXL.

	Preoperative	1 year postoperative	value
CDVA (decimal)	0.76 ± 0.06	0.815 ± 0.05	0.013
UCVA (decimal)	0.32 ± 0.05	0.40 ± 0.05	0.002
K max (diopters)	47.19 ± 1.62	46.87 ± 0.77	0.308
Pachymetry at thinnest location (microns)	467.30 ± 3.39	460.72 ± 22.17	0.097

CDVA: corrected distance visual acuity; UCVA: uncorrected visual acuity; K: keratometry; ACXL: accelerated collagen cross-linking.
