文摘Purposes:To evaluate the rotational stability and astigmatic correction of a C-loop frosted haptic toric intraocular lens(IOL)compared with a plate-haptic toric IOL with/without capsular tension ring(CTR)implantation in cataractous eyes with high rotation risk due to large white-to-white(WTW)distance.Methods:This retrospective cohort study included 90 cataractous eyes with WTW>11.8 mm,which received implantation of either a C-loop frosted haptic toric IOL(Group ZCU),a plate-haptic toric IOL(Group 709),or a plate-haptic toric IOL with CTR(Group 709+CTR).IOL rotation and residual astigmatism were assessed one month postoperatively.Results:Group ZCU demonstrated significantly better rotational stability,with a mean rotation of 1.87°±1.03°,compared to 4.63°±2.12°in Group 709 and 4.13°±1.86°in Group 709+CTR(both P<0.05).Residual astigmatism was also significantly lower in Group ZCU(0.36±0.26 D),compared to Group 709(0.54±0.43 D)and Group 709+CTR(0.65±0.27 D;both P<0.05).A positive correlation between WTW and IOL rotation was found in Group 709(r=0.419,P=0.021)and Group 709+CTR(r=0.403,P=0.027),but not in Group ZCU(r=-0.180,P=0.341).Lens thickness and WTW were identified as independent predictors of rotation in Group 709,whereas only WTW was significant in Group 709+CTR.Conclusions:In eyes with high rotation risk due to large WTW(>11.8 mm),the ZCU IOL exhibits superior rotational stability and astigmatic correction compared to the 709 IOL,regardless of whether CTR is used.
