Effect of Mitomycin C on Myopic versus Astigmatic Photorefractive Keratectomy

Table 1

A 1-year postoperative comparison of patients with simple myopia with/without MMC and astigmatic patients with/without MMC. An ANOVA test compared the four groups.

Variable	Simple myopia		value	Astigmatism		value	ANOVA (four groups)
	MMC	No MMC	Paired t-test	MMC	No MMC	Paired t-test
UCVA (in logMAR)	0 ± 0	0.1 ± 0.141		0.04 ± 0.137	0 ± 0		0.4624
BCVA (in logMAR)	0 ± 0	0.05 ± 0.070		0.04 ± 0.137	0 ± 0		0.5193
Refractive error	0	−0.03 ± 0.08		−0.027 ± 0.098	−0.016 ± 0.056		0.4798
K-reading	39.23 ± 2.1	40.58 ± 1.23		39.33 ± 1.7	40.98 ± 1.35		0.0049
Haze formation	0	0.14 ± 0.287		0	0.31 ± 0.32		<0.0001

ANOVA: analysis of variance; BCVA: best-corrected visual acuity; MMC: mitomycin C; UCVA: uncorrected visual acuity.
