The success of the IOL depends on the capacity to reduce the astigmatism and the stability of the crystalline capsule. It has been observed that IOLs suffer rotation, frequently because of the capsule shrinking. Purpose: To evaluate the postoperative rotational stability of the toric intraocular lens (IOL) Acrysof and its refractive outcome during the first 3 postoperative months. Methods: A retrospective observational study, including 9 eyes of 8 patients that had a cataract or a phaco-refractive surgery with a corneal astigmatism of at least 1.50 Diopters (D), in which we implanted an Acrysof toric IOL. Results: The mean preoperative astigmatism of the patients was 2.25 D. ±. 0.5, being 77[%] with the rule and 23[%] against the rule. The mean IOL rotation from baseline to 3 months postoperatively was 3.94 degrees. ±. 2.44. This rotation caused a 0.27D. ±. 0.17 loss of astigmatic IOL power. The mean residual refractive astigmatism was 0.75D. ±. 0.48 at one month and 0.63D. ±. 0.87 at three months. Conclusion: In this study the Acrysof toric lens showed rotational stability and an acceptable refractive result. © 2015 Sociedad Mexicana de Oftalmologi
