Refractive and Quality of Vision Outcomes with Toric IOL Implantation in Low Astigmatism

Table 2

Visual function results. There was a statistically significant difference between the preoperative and postoperative periods when the following visual functions were compared (): UCVA, BCVA, and CS.

Function	Preoperative mean	Preoperative SD	Postoperative mean	Postoperative SD	Range of means	value
UCVA (decimal)	<0.20	0.17	0.80	0.19	0.60	<0.001^α
BCVA (decimal)	0.28	0.15	0.97	0.15	0.69	<0.001^β
CS (log)	1.22	0.32	1.74	0.19	0.52	<0.001^α

UCVA = uncorrected visual acuity; BCVA = best-corrected visual acuity; CS = contrast sensitivity.
α = paired -test; β = Wilcoxon signed-rank test.
