Prospective Cohort Study on Refractive Changes after Trabeculectomy

Table 5

Multivariate analysis for determining prognostic factors for refractive myopic progression after trabeculectomy using a logistic regression model.

Variable	RR (95% Cl)	value
Type of glaucoma (exfoliation glaucoma/other)	1.94 (0.30–12.1)	0.47
Age per year	0.96 (0.86–1.07)	0.49
Preoperative LogMAR BCVA per 1.0	5.02 (0.41–81.7)	0.20
Conjunctival incision (fornix-based/limbus-based)	0.81 (0.09–6.26)	0.84
Axial length per mm	0.79 (0.42–1.38)	0.42
Preoperative nuclear color grade per 1.0	2.46 (0.73–9.63)	0.15
Nuclear color grade change per 1.0	12.1 (3.17–71.8)	<0.001

BCVA, best corrected visual acuity; 95% CI, 95% confidence interval; LogMAR, logarithm of minimum angle of resolution; RR, relative risk.
