This prospective comparative study aimed to investigate the influence of diffractive trifocal intraocular lenses (IOLs) implantation on standard automated perimetry.
Patients with no diseases affecting the visual field had undergone cataract surgery following the implantation of trifocal or monofocal IOLs from July 2019 to August 2020 were recruited. The normality of the anterior and posterior segments and absence of glaucomatous optic nerve cupping were confirmed preoperatively by slit-lamp examination. Standard automated perimetry was performed using Humphrey Visual Field 10-2 testing, 2-3 months after cataract surgery in only one eye per patient. The mean deviation (MD) and foveal sensitivity were compared between IOLs in eyes with acceptable reliability indices and best-corrected visual acuity of 20/25 or better.
Among the 83 eyes of the 83 patients included, 39 and 29 eyes eligible for perimetry analysis had trifocal and monofocal IOLs, respectively. The mean MD and foveal sensitivity in eyes with trifocal IOLs were significantly lower than those in eyes with monofocal IOLs (P < 0.021), with mean differences of 0.77 and 1.01 dB, respectively.
The comparison in nonglaucomatous eyes demonstrated that the influence of trifocal IOLs on standard automated perimetry was greater than that of monofocal IOLs.
本前瞻性对照研究旨在探讨散光三焦点人工晶状体（IOL）植入对标准自动视野计的影响。
招募了 2019 年 7 月至 2020 年 8 月期间接受白内障手术并植入三焦点或单焦点 IOL 的无影响视野疾病的患者。术前通过裂隙灯检查确认眼前段和后段正常，无青光眼视神经杯。在每个患者的一只眼中，在白内障手术后 2-3 个月使用 Humphrey 视野 10-2 测试进行标准自动视野计检查。仅当可接受的可靠性指数和最佳矫正视力为 20/25 或更好时，才比较 IOL 之间的平均偏差（MD）和中央凹敏感度。
在纳入的 83 例 83 眼中，有 39 只眼和 29 只眼分别适合进行视野分析，这些眼分别植入了三焦点和单焦点 IOL。三焦点 IOL 眼中的平均 MD 和中央凹敏感度明显低于单焦点 IOL 眼中的平均 MD 和中央凹敏感度（P<0.021），差异均值分别为 0.77 和 1.01dB。
在非青光眼眼中的比较表明，三焦点 IOL 对标准自动视野计的影响大于单焦点 IOL。
