The influence of a modified haptic on preventing toric IOL rotation in high rotation risk eyes

This is the authors' abstract. We don't add key points for this paper.

Purpose: 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: = 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.
