Objective To evaluate the decentration ,tilt and rotation stability of Acrysof Toric intraocular lens (IOL) using Anterior Segment Analyzer (Pentacam)  combined anterior segment photograph.

Methods This study comprised100 cataractous eyes of 76 patients with preexisting rule corneal astigmatism having phacoemulsification and Acrysof Toric intraocular lens implantation. The patients were followed up for 15 ± 2.3 months.Pentacam and anterior segment photograph were used to assess the decentration, tilt and rotation stability of Acrysof Toric intraocular lens (IOL).

Results 1 day after surgery, the average IOL rotation was (3.18 ± 3.47)°.IOL rotated 10 ° or less accounted for 94% .The average decentration was (0.27 ± 0.07) mm .The average tilt was (2.00± 0.70) °. 1 year after surgery, the average rotation was (3.72 ± 3.55) °, theaverage decentration was (0.29 ± 0.08) mm and the average tilt was (2.04 ±0.65) °. The IOL and posterior capsule attached closely, with no capsular bag shrinkage.

Conclusion Toric IOL has good stability and centration.
