Table 1

Main demographic and clinical characteristics data.

	Group A	Group B	value	Total
Phaco cases	185	317		502
per resident	[61.67 ± 27.6	63.4 ± 19.7	0.93
Gender	88F/75M	161F/143M	0.87	249F/218M
Age (years)	73.4 ± 10.9	72.8 ± 9.2	0.53	73.1 ± 10.5
Axial length (mm)	23.8 ± 3.7	23.6 ± 4.2	0.59	23.7 ± 4.1
Preoperative MRSE	0.39 ± 1.4	0.45 ± 1.5	0.68	0.42 ± 1.5
Postoperative MRSE	−0.32 ± 0.2	−0.35 ± 0.2	0.11	−0.34 ± 0.4
IOL power	21.3 ± 2.7	21.6 ± 2.9	0.25	21.5 ± 2.9

MRSE = manifest refractive spherical equivalent; IOL = intraocular lens.
Student’s -test was used for comparing data between Group A and Group B in the following parameters: age, axial length, and IOL power.
Mann-Whitney U test was used for comparing data between Group A and Group B in the following parameters: phaco cases per resident, preoperative MRSE, and postoperative MRSE.
Fisher’s exact test was used for comparing data between Group A and Group B in the following parameter: gender.
