Abstract
A study of 90 eyes in 78 patients was done to study stability of Toric IOLs. Patients with astigmatism of 0.75 D to 4 D were included. Exclusion criteria was irregular corneal astigmatism, post refractive surgery, corneal dystrophies. All patients underwent uncomplicated phacoemulsification by the same surgeon. 9 eyes with astigmatism of 0.75 D to 1.5 D were implanted with the AcrySof SA60T3 IOL, 24 eyes with astigmatism between 1.5 D to 2.0 D received the SA60T4 IOL, 24 eyes with astigmatism between 2.0 D to 2.50 D received the SA60T5 and 33 eyes with astigmatism of 2.5 D & higher received SA60T6 and above models. The postop position of the IOL was assessed at 1 week, 1 month and 6 months. The postop rotation was within 5 degrees in 95% of cases. IOL rotation happens mostly within 1st month of surgery, and requires early repositioning. Toric IOLs are very effective in correcting astigmatism during the cataract surgery and demonstrate rotational stability in the capsular bag.
