    Purpose. To evaluate the effectiveness of the implantation of toric intraocular lenses was studied in patients with cataracts and complex ametropia caused by concomitant pathology and due to previous operations.

    Material and methods. 24 patients (31 eyes) with cataracts and complex ametropia were operated. Corneal astigmatism before surgery was more than 1.5 diopters.

    Results. All patients managed to achieve a significant reduction in the cylindrical component of subjective refraction and to obtain high visual acuity without correction. The magnitude of the residual astigmatism was 0.74 ± 0.12 diopters.

    Conclusion. Intraocular correction of astigmatism with toric IOLs during phacoemulsification in patients with complex ametropia is an effective method and allows to obtain high visual functions after one-stage surgical treatment
