To compare visual outcomes after implantation of two models of diffractive trifocal IOLs using various vision assessment systems.
The study included 25 patients (25 eyes) who were implanted with AcrySof IQ PanOptix (TFN) and 25 patients (25 eyes) implanted with AT LISA tri 839 MP (TRI). Postoperative examination at 1 year included assessment of monocular visual acuity for far, intermediate and near distance using decimal scale, as well as LogMAR and an interactive computer program (ICP). Contrast sensitivity was assessed with the Optec 6500 device. A questionnaire was used to evaluate subjective quality of vision and the intensity of optical phenomena.
Uncorrected visual acuity (UCVA) at distance, intermediate and near was better in the TFN group in comparison with the TRI group as measured with decimal scale, ICP and LogMAR. Under photopic and mesopic conditions with and without glare, at all spatial frequencies the contrast sensitivity function (CSF) was higher after implantation of TFN in comparison with TRI. The average VF-14 score was 97.2 after implantation of TFN and 96.7 after implantation of TRI. The amount of patients who required spectacle correction after the surgery was 5.5% less in the TFN group compared to the TRI group.
High visual outcomes at all distances were observed in patients after implantation of both trifocal IOLs with TFN showing a slight advantage. Evaluation of the visual outcomes using various systems showed the benefits of the ICP assessment. The CSF had typical configuration with maximum value in the mid-range region and a decrease in the high-frequency range after implantation of both IOLs, however the indicators were better in the TFN group. The postoperative period was characterized by high levels of patient satisfaction and spectacle independence in both groups.
使用多种视力评估系统比较两种衍射型三焦点人工晶状体植入后的视觉效果。
该研究纳入了25例（25只眼）植入AcrySof IQ PanOptix（TFN）的患者和25例（25只眼）植入AT LISA tri 839 MP（TRI）的患者。术后1年的检查包括使用小数视力表、LogMAR视力表以及交互式计算机程序（ICP）评估远、中、近距离的单眼视力。使用Optec 6500设备评估对比敏感度。通过问卷调查评估主观视觉质量和光学现象的强度。
与TRI组相比，TFN组在远、中、近距离的未矫正视力（UCVA）用小数视力表、ICP和LogMAR测量时更好。在明视和中视条件下，无论有无眩光，在所有空间频率下，TFN植入后对比敏感度函数（CSF）均高于TRI。TFN植入后平均VF - 14评分为97.2，TRI植入后为96.7。与TRI组相比，TFN组术后需要眼镜矫正的患者数量少5.5%。
两种三焦点人工晶状体植入患者后在所有距离均观察到较高的视觉效果，TFN显示出轻微优势。使用多种系统评估视觉效果显示了ICP评估的益处。两种人工晶状体植入后CSF具有典型构型，在中频区域有最大值，高频区域下降，然而TFN组的指标更好。两组术后患者满意度高且无需依赖眼镜。
