Comparing the Effect of Monofocal and Multifocal Intraocular Lenses on Macular Surgery

Table 3

The mean refractive error, IOL decentration, and macular surgery of the groups.

	Monofocal IOL (group 1)		Multifocal IOL (group 2)
	Mean ± SD/(n − %)	Median	Mean ± SD/(n − %)	Median
Spherical refraction error (D)	0.56 ± 0.26	0.50	0.52 ± 0.27	0.50	0.628 m
IOL decentration (mm)	1.07 ± 1.23	0.00	0.93 ± 1.22	0.00	0.622 m
Macular surgery time (sec)	191.5 ± 71.5	158.0	305.3 ± 157.3	292.0	0.013 m

m: Mann−WhitneyU-test; X²: chi-square test; w: Wilcoxon test; D: diopter; mm: millimeter; sec: second; BCVA: best corrected visual acuity.
