A retrospective study of 30 eyes in 29 patients. All patients with regular astigmatism of range 1.5 D to 4 D were included in the study. All patients underwent similar uncomplicated phacoemulsification cataract surgery by the same surgeon. Intraoperatively, the axis of the toric lens was aligned to the steepest axis of the corneal astigmatism. Main outcome measure was the postoperative position of the lens, assessed at 1 week, 1 month and 6 months, using toric marker and the slit lamp. The post op rotation was within 5 degrees in 95% of cases. No lens showed more than 9 degrees of rotation, and no lens required secondary repositioning. However, IOL rotation happens mostly within 1st month of surgery, and if it is significant, it requires early repositioning. CToric IOLs are very effective and consistent in correcting astigmatism during the cataract surgery. Once placed to its position, toric IOL lenses demonstrate rotational stability in the capsular bag.
