Table 6 Characteristics of 4 large rotation cases (> 15°)

Parameters	Case1	Case2	Case3	Case4
ACD (mm)	2.67	2.63	2.71	2.77
ACV (mm3)	127	122	110	161
LT (mm)	4.4	6.15	4.34	4.51
VL (mm)	19.55	19.58	18.32	18.88
AL (mm)	27.34	26.78	26.2	26.96
Preoperative total corneal astigmatism (D)	1.3	3	2.6	1.5
Spherical power of IOL (D)	15	15	13	17
Toric IOL models	ZCT150	ZCT400	ZCT300	ZCT225
Intraoperative IOL axis (degree)	158	88	92	81
Area of capsulorhexis (mm2)	17.8	21.37	18.83	31.16
Area of overlap between capsulorhexis and optic (mm2)	10.46	6.89	9.43	1.58
K1(D)	44.4	43.4	43.2	40.4
K2(D)	45.7	46.4	45.8	41.9
Absolute value of rotation 1 month postoperatively (dgree)	16	33	40	79
Absolute value of rotation 3 months postoperatively (dgree)	16	33	40	79

In Case4, the area of capsulorhexis was largest (31.16 mm2), the area of overlap between capsulorhexis and optic was smallest (1.58 mm2). As a result, the toric IOL rotation reached 79°at 3 months after surgery
