Table 1 Descriptive measures for postoperative spherical equivalent, postoperative visual acuities and mesopic pupillometry in Groups A and B

	Mean ± SD (Min-max)		P-value
Measurement	Group A (n=28)	Group B (n=26)
UDVA	−0.00±0.05	0.09±0.10	<0.001*
UIVA	0.20±0.04	0.39±0.09	<0.001*
UNVA	0.16±0.08	−0.01±0.09	<0.001*
SE	−0.09±0.23	0.07±0.21	0.02*
CDVA	−0.02±0.05	0.06±0.12	0.001*
AL	23.43±0.94	23.06±0.89	0.13
Pupilometry (mesopic)	4.56±0.87	4.60±1.04	0.94

Notes: *=Kruskal–Wallis. Group A represents the EDOF group and Group B represents the Trifocal group. Postoperative UDVA was better in Group A (0.00±0.05 vs 0.09±0.10 logMAR, P<0.001). CDVA was better in Group A (−0.02±0.05 vs 0.06±0.12, P=0.001). UIVA and UNVA had statistical significance as well. Group A performed better for UIVA: 0.20±0.04 vs 0.39±0.09, P<0.001 and Group B performed better for UNVA: 0.16±0.08 vs −0.01±0.09, P<0.001, respectively. The postoperative data of spherical equivalent (SE) comparison also had statistical significance; nevertheless, axial length (AL) and pupil diameter (PD) had no statistical significance.

Abbreviations: SE, postoperative spherical equivalent; UDVA, postoperative uncorrected distance visual acuity; UIVA, postoperative uncorrected intermediate visual acuity; UNVA, postoperative uncorrected near visual acuity; CDVA, postoperative corrected distance visual acuity; AL, axial lens.
