To evaluate the visual quality and performance of TECNIS Symfony intraocular lenses (IOLs) implanted with or without micro-monovision approach. Chongqing Aier Mega Eye Hospital, Chongqing, China; Daping Hospital of Army Medical University, Chongqing, China. Prospective study. The study comprised 70 cataract patients who had bilateral implantation of TECNIS Symfony extended range of vision IOLs, either with intended micro-monovision (monovision group: 35 patients) or with intended emmetropia (control group: 35 patients). Visual acuity, modulation transfer function (MTF), defocus curve, spectacle independence, and photic phenomena were analyzed 3 months postoperatively. There was no significant difference between the two groups in binocular uncorrected visual acuity at distance. Mean binocular uncorrected visual acuity at intermediate (monovision: 0.81 dec; control: 0.58 dec) and near (monovision: 0.59 dec; control: 0.30 dec) were significantly better in the monovision group. In the monovision group, the difference of MTF values between the dominant and the non-dominant eyes was not statistically significant and MTF values were within the normal range for both eyes. Spectacle independence at intermediate and near was statistically significantly higher in the monovision group compared to the control group. The incidence of photic phenomena was similar in both groups. Micro-monovision implantation of TECNIS Symfony IOLs provided a superior range of visual acuity from far to near and higher spectacle independence compared to a control group targeted for emmetropia.
评估采用或不采用微单眼视方法植入的TECNIS Symfony人工晶状体（IOL）的视觉质量和性能。中国重庆爱尔麦格眼科医院；中国重庆陆军军医大学大坪医院。前瞻性研究。该研究纳入了70例双侧植入TECNIS Symfony扩展视程IOL的白内障患者，其中采用预期微单眼视的患者为单眼视组（35例），采用预期正视的患者为对照组（35例）。术后3个月分析视力、调制传递函数（MTF）、散焦曲线、脱镜率和光现象。两组间远距离双眼未矫正视力无显著差异。单眼视组中距离（单眼视：0.81对数视力单位；对照：0.58对数视力单位）和近距离（单眼视：0.59对数视力单位；对照：0.30对数视力单位）的平均双眼未矫正视力明显更好。在单眼视组中，优势眼和非优势眼之间的MTF值差异无统计学意义，且双眼的MTF值均在正常范围内。与对照组相比，单眼视组在中距离和近距离的脱镜率在统计学上显著更高。两组光现象的发生率相似。与以正视眼为目标的对照组相比，TECNIS Symfony IOL的微单眼视植入提供了从远到近更好的视力范围和更高的脱镜率。
