The first experience in clinical application of multifocal IOL AcrySof® IQ ReSTOR® Toric

Purpose

Clinical results analysis of the first implantations of toric multifocal IOL AcrySof® IQ ReSTOR® Toric in patients with presbyopia and corneal astigmatism.

Methods

There are included in the research 22 eyes (11 patients) with a cataract, refractive abnormalies and presbyopia (preoperative corneal astigmatism from 1.0 to 3.0D) after binocular implantations of AcrySof® IQ ReSTOR® Toric — the basic group (BG). The mean age of patients was 49.5±11.5 years (from 34 to 67 years). The mean spherical component (SC) before operation was 2.8±1.1D (from+3.25 to — 4.75D), cylindrical component (CC) — 1.9±0.5D (from 1.0 to 3.0D). Follow up: up to 4 months. The control group (CG) consisted of 40 eyes (20 patients) after +3.0D AcrySof® IQ ReSTOR® implantations with a similar index of age, cataract maturation degree, and the corneal astigmatism was ≤1.5D.


Results

There were no intra- and post-operative complications. One month after the operation the uncorrected visual distance acuity (UCVDA) was 0.8 and better in 89% of cases, the intermediate VA had the same data in 82% of patients, the near VA — in 75% of patients with ReSTOR IQ Toric. The UCVDA 1.0 or better was in 72% of patients, the intermediate VA — only in 25%, and the near VA — in 45% of patients. The residual SC in the BG was 0.39±0.20D, the CC — 0.33±0.75D, in the CG: SC — 0.37±0.21D, CC — 0.75±0,20D. IOL rotation from the planned axis did not exceed 5-7°. Indices of visual acuity, refraction and satisfaction of patients achieved 94% in the basic group and were better, than in the control group.


Conclusion

Implantation multifocal IOL AcrySof® IQ ReSTOR® Toric in patients with presbyopia and corneal astigmatism allows to obtain high visual results and to get rid of spectacle correction in 95% of cases, applying only one stage of surgery that reduces a risk of intra- and post-operative complications, accelerates terms of patients’ rehabilitation, and raises the general satisfaction in results of treatment.
