Abstract Details


Evaluate the clinical results of toric intraocular lenses (TIOL) implantation of patients with corneal astigmatism.


Kazakh scientific research institute of eye diseases


We observed 103 eyes aged 30 to 76 years. All patients were divided into 2 groups: 1- 47 eyes - soft intraocular lens implanted. 2- 56 soft TIOL implanted. The scatter in the values of corneal astigmatism in group 1 ranged from 1.0 dioptres (dpt) to 2.5, in second - from 1.0 to 3.0 dpt. Maximum corrugated visual acuity in group 1 was 0.1 to 0.8, in second - 0.08 to 0.9. By biomicroscopy turbidity in different parts of the lens was observed at all patients. Operation technology carried out by conventional methods. The postoperative period was uneventful and uncomplicated.


In the early postoperative period visual acuity and refraction was assessed. The final results were assessed one month after surgery. Keratometry Data of all patients virtually unchanged. Refractometry data in group 1 ranged from 1.0 to 2.75 diopters, in group 2 - from 0 to 0.25 diopters. In 60% of cases the residual cylindrical component - 0.25 diopters. Non-corrugated visual acuity in group 1 – from 0.1 to 0.6, in group 2 - from 0.7 to 1.0. Maximum corrugated visual acuity in group 1- from 0.4 to 1.0, in group 2 - from 0.8 to 1.0


Thus, the resulting toric IOL implantation in the initial astigmatism of 1 to 3 dioptres full correction of astigmatism is achieved in 40% of cases. In 60% of the residual astigmatism was 0.25 diopters. The use of toric IOLs in cataract surgery has allowed to reach high functional results when combined cataract with corneal astigmatism.
