Clinical efficacy of implantation of toric intraocular lenses with different incision positions: a comparative study of steep-axis incision and non-steep-axis incision

Table 1 Comparisons of patient characteristics between the two groups

Parameter	Steep-axis	Non-steep-axis	P value
Age (year)	60.83 ± 12.47	63.90 ± 15.03	0.393
Gender (Male/Female)	10/20	11/19	0.787
Operated eye (Right/Left)	14/16	17/13	0.438
UCVA (logMAR)	0.81 ± 0.31	0.78 ± 0.28	0.684
BCVA (logMAR)	0.55 ± 0.25	0.63 ± 0.25	0.227
AXL (mm)	25.42 ± 2.20	24.70 ± 1.89	0.182
NC grades	2.90 ± 0.53	2.88 ± 0.58	0.908
Corneal astigmatism (D)	2.09 ± 0.55	2.05 ± 0.57	0.790
Incision position (°)^*	0.00 ± 0.00	29.80 ± 16.33	<0.001

Values are presented as the mean ± standard deviation or n
Abbreviations: UCVA = uncorrected visual acuity; BCVA = best-corrected visual acuity; AXL = axial length; logMAR = logarithms of the minimal angle of resolution; IOL = intraocular lens
*Data of incision position was the angular deviation from the steep meridian
No significant differences were found between the two groups except incision position (Student’s t test or Chi-square test)
