The aim of this study was to analyze the objective and subjective visual outcomes of patients bilaterally implanted with the extended range of vision intraocular lens (EROV IOL), the Tecnis Symfony.
This was a prospective interventional case series conducted at a tertiary eye care hospital in South India. The study included patients with bilateral implantation of EROV IOLs. The uncorrected and corrected visual acuity for distance, intermediate, and near vision was recorded at 6 weeks and 6 months' postoperative visit. A subjective questionnaire was administered to assess spectacle independence, photic phenomenon, and overall satisfaction. All data were recorded using Microsoft Excel worksheet. The analyses were performed using SPSS for windows software.
Our study included fifty patients with bilateral implantation of EROV IOLs. The mean age was 59.84 ± 11.68 years. The mean uncorrected binocular distance, intermediate, and near visual acuity (in standard decimal equivalent) was 0.89,0.99 and 0.99 respectively, at 6 months' postoperative visit. Ninety-six percent of the patients did not require spectacles for distance and 98% of the patients were free from spectacles for intermediate and near vision. 94% of our patients perceived no or minimal photic phenomena such as glare and halos. The mean subjective patient satisfaction score (out of 10) for distance, intermediate, and near was 9, 10, and 9, respectively.
The EROV IOLs demonstrated high levels of spectacle independence for distance, intermediate, and near vision. The incidence of photic phenomena observed was minimal with a high level of patient satisfaction.
本研究旨在分析双侧植入扩展视程人工晶状体（EROV IOL），即 Tecnis Symfony 的患者的客观和主观视觉结果。
这是在印度南部一家三级眼科医院进行的前瞻性干预性病例系列研究。该研究包括双侧植入 EROV IOL 的患者。在术后 6 周和 6 个月的随访中，记录未矫正和矫正的远、中、近视力。通过主观问卷评估患者对眼镜的依赖程度、视觉光现象和总体满意度。所有数据均使用 Microsoft Excel 工作表记录。使用 SPSS for windows 软件进行分析。
本研究共纳入 50 例双侧植入 EROV IOL 的患者。平均年龄为 59.84 ± 11.68 岁。术后 6 个月，平均双眼未矫正远、中、近视力（以标准十进制等效值表示）分别为 0.89、0.99 和 0.99。96%的患者不需要戴眼镜看远，98%的患者无需戴眼镜看中、近视力。94%的患者没有或几乎没有视觉光现象，如眩光和光晕。患者对远、中、近视力的平均主观满意度评分（满分 10 分）分别为 9、10 和 9。
EROV IOL 为远、中、近视力提供了高度的眼镜独立性。观察到的视觉光现象发生率较低，患者满意度较高。
