PURPOSE:

To investigate the factors affecting near vision spectacle dependence after mix-and-match implantation of the trifocal extended depth of focus (EDOF) and trifocal intraocular lens (IOL).

METHODS:

A total of 204 eyes of 102 patients who underwent mix-and-match implantation of one trifocal EDOF and one trifocal IOL were enrolled in this study. Patients were divided into two groups according to spectacle dependence for near vision: reading glasses and no glasses. Clinical characteristics were compared between the two groups and multivariate binary logistic regression analysis was performed to determine the odds ratio of factors potentially associated with the need for reading glasses.

RESULTS:

Eighty-one patients (79.4%) did not need reading glasses and 21 (20.6%) did. The mean age of the no glasses group (55.6 ± 5.6 years) was significantly higher than that of the reading glasses group (52.7 ± 4.1 years). Preoperative refractions were more myopic in the reading glasses group than in the no glasses group. The postoperative uncorrected near visual acuities were better and the satisfaction scores were higher in the no glasses group compared to the reading glasses group. Multivariate binary regression analysis revealed that only pre-operative spherical equivalent (odds ratio: 1.397; P = .025) was related to the spectacle independence for near vision.

CONCLUSIONS:

Patients who had preoperative myopia and underwent mix-and-match implantation of trifocal EDOF and tri-focal IOLs tended to need spectacles for near vision. Surgeons should be aware of patients with myopia when considering mix-and-match implantation of trifocal EDOF and trifocal IOLs.

目的：

探讨混合匹配植入三焦点扩展焦深（EDOF）和三焦点人工晶状体（IOL）后近视力眼镜依赖性的影响因素。

方法：

本研究共招募了 102 名患者的 204 只眼，他们接受了一个三焦点 EDOF 和一个三焦点 IOL 的混合匹配植入。根据对近视力的眼镜依赖性将患者分为两组：老花镜组和不戴镜组。比较两组的临床特征，并进行多变量二元逻辑回归分析以确定可能与需要老花镜相关的因素的优势比。

结果：

81 名患者 (79.4%) 不需要老花镜，21 名 (20.6%) 需要。不戴眼镜组的平均年龄（55.6 ± 5.6 岁）明显高于戴老花镜组（52.7 ± 4.1 岁）。老花镜组的术前屈光度比不戴眼镜组更近视。与戴老花镜组相比，不戴眼镜组术后裸眼近视力更好，满意度得分更高。多元二元回归分析显示，只有术前等效球镜（优势比：1.397；P = .025）与近视力的眼镜独立性有关。

结论：

术前近视并接受三焦点 EDOF 和三焦点 IOL 混合匹配植入的患者往往需要近视眼镜。在考虑混配植入三焦点 EDOF 和三焦点 IOL 时，外科医生应注意近视患者。
