Abstract

Purpose. To study the data of low astigmatism correction after multifocal and multifocal toric intraocular lens implantation. Material and methods. We examined 64 patients (77 eyes) with corneal astigmatism 0.5–0.75 D, of them 34 patients (38 eyes) underwent phacoemulsification (PE) with Acrysof IQ PanOptix Toric IOL implantation (group 1 or main group), and 31 patients (39 eyes) — with Acrysof IQ PanOptix IOL implantation (group 2 or control group). Results. 1 months after PE the sphere of ±0.5 D was observed in 92.1 % of cases in the main group and in 74.4 % in the control group. Residual astigmatism with PanOptix Toric implants was –0.18 ± 0.07 D in the main group and 0.91 ± 0.25 D in the control group. By 3 months after surgery uncorrected visual acuity (UCVA) of 0.8 and better was observed in 94.7 % of cases in the main group and in 82.1 % (p < 0.05) in the control group. Near visual outcomes under photopic and mesopic lighting conditions in the two groups after 6 months of follow-up did not make big difference. When assessing the mid vision, the control group showed significantly lower UCVA values. Questionnaire data (according to VFQ-14): the average value in the main group — 96.7 ± 1,2 points (variability 95.1–100), in the control group — 82.8 ± 2.3 (78.6–92.3), the difference was statistically significant (p < 0,05). Conclusion. The comparative analysis showed that PE with multifocal toric IOL implantation in small cylinder astigmatism (0.5–0.75 D) results in better mid and distaance visual acuity under different lighting conditions than PE with multifocal IOL implantation. Therefore, when choosing an IOL in this category of patients, it is preferable to implant multifocal toric IOLs.
