PURPOSE To assess visual outcomes and patient satisfaction for trifocal and extended depth of focus (EDOF) intraocular lenses (IOLs) compared to monofocal IOLs with and without monovision. METHODS Consecutive patients underwent bilateral cataract extraction surgery and implantation of either monofocal IOLs, monofocal IOLs using monovision, EDOF IOLs, or trifocal IOLs. Patients with preoperative biometric data, postoperative refraction, and visual acuity who completed a questionnaire regarding satisfaction and side effects were included. Visual outcome, spectacle independence, patient satisfaction, and subjective photic phenomena were assessed. RESULTS Each group comprised 50 patients (100 eyes). The mean postoperative uncorrected distance, intermediate, and near visual acuities (logMAR) were: 0.17 ± 0.14 (Snellen 20/30), not applicable, and not applicable for monofocal; 0.08 ± 0.12 (Snellen 20/24), not applicable, and 0.07 ± 0.12 (Snellen 20/23) for monovision; 0.03 ± 0.08 (Snellen 20/21), 0.08 ± 0.12 (Snellen 20/24), and 0.23 ± 0.17 (Snellen 20/34) for EDOF; 0.07 ± 0.09 (Snellen 20/23), 0.08 ± 0.11 (Snellen 20/24), and 0.02 ± 0.06 (Snellen 20/21) for trifocal. Spectacle independence was reported by 36%, 70%, 74%, and 92% of patients, respectively. Postoperative halos and/or glare were experienced by 2%, 6%, 14%, and 38%, respectively, of which 2%, 0%, 6%, and 10%, respectively, were functionally disturbing. A total of 64%, 72%, 78%, and 76%, respectively, would choose the same IOL again. CONCLUSIONS Patient satisfaction rates were high in all groups. Trifocal IOLs were more effective in improving unaided whole range of vision, but were associated with a higher rate of photic phenomena. The EDOF IOL and monovision provided partial spectacle independence with less photic phenomena. [J Refract Surg. 2019;35(7):434-440.].

三焦点，聚焦深度扩大和单焦点人工晶状体的视觉结果和患者满意度。

目的评估三焦和扩展景深（EDOF）人工晶状体（IOL）与单眼IOL（有或无单眼）的视觉效果和患者满意度。方法连续患者接受双侧白内障摘除手术，并植入单焦点IOL，使用monovision的单焦点IOL，EDOF IOL或三焦点IOL。包括具有术前生物统计学数据，术后屈光度和视力的患者，这些患者填写了有关满意度和副作用的问卷。评估视觉结果，眼镜独立性，患者满意度和主观的光感现象。结果每组包括50例患者（100眼）。术后平均未矫正距离，中度和近视力（logMAR）为：0.17±0.14（Snellen 20/30），不适用，不适用于单焦点；0.08±0.12（Snellen 20/24）（不适用）和0.07±0.12（Snellen 20/23）（用于单眼）；对于EDOF，0.03±0.08（Snellen 20/21），0.08±0.12（Snellen 20/24）和0.23±0.17（Snellen 20/34）; 对于三焦点，0.07±0.09（Snellen 20/23），0.08±0.11（Snellen 20/24）和0.02±0.06（Snellen 20/21）。分别有36％，70％，74％和92％的患者报告了眼镜独立性。术后光晕和/或眩光分别发生2％，6％，14％和38％，其中分别有2％，0％，6％和10％引起功能障碍。总共分别有64％，72％，78％和76％的用户会再次选择相同的IOL。结论在所有组中患者满意度都很高。三焦点人工晶体在改善独立视力范围方面更有效，但与光合现象的发生率较高有关。EDOF IOL和monovision提供了部分眼镜独立性，且具有较少的光影现象。[J Refract Surg。2019; 35（7）：434-440。]。
