Abstract

90 patients with regular astigmatism of range 0.75 D to 4 D were included in the

study. Exclusion criteria included irregular corneal astigmatism, post refractive

surgery, corneal dystrophies, problems encountered during surgery. Cataract

surgery in all patients was done by phacoemulsification by the same surgeon using

Alcon AcrySof Toric IOLs. The postoperative position of the lens was assessed at 1

week, 1 month and 6 months, using a toric marker with patient on the slit lamp.

There was no significant rotation of IOL observed during followup. Overall, the post

op rotation was within 5 degrees in 95% of cases. Both clockwise and anti clockwise

rotation was recorded, with no obvious preference for either. However, IOL rotation

happened mostly within 1st month of surgery. Conclusion: Toric IOLs are very

effective and consistent in correcting astigmatism during the cataract surgery and

once they are in position, they demonstrate good rotational stability in the capsular

bag.
