Purpose. To evaluate 2-year visual acuities and questionnaire after bilateral implantation of SN6AD1 multifocal intraocular lens (MIOL) or SN60WF IOL. Methods. Patients randomly scheduled for bilateral implantation of SN6AD1 MIOL and SN60WF IOL with 2-year follow-up were enrolled. Uncorrected/corrected distance and near visual acuity, uncorrected intermediate visual acuity at 63 cm under high and low contrast, reading activity, the defocus curve, and a quality-of-life questionnaire were evaluated. Results. Each group comprised 20 patients. Uncorrected intermediate visual acuities and uncorrected near visual acuity were better in SN6AD1 group than in SN60WF group (P = 0.005, P = 0.011, and P < 0.001). In SN6AD1 group, the uncorrected intermediate and near visual acuities 1 year and 2 years postoperatively were reduced than postoperative 3-month outcomes, respectively. SN6AD1 group reported superior overall spectacle independence and inferior satisfaction. SN6AD1 group had a longer reading newspaper duration than SN60WF group (P = 0.036). When using mobile phone, SN6AD1 group had a more comfortable distance than SN60WF group (P < 0.001) and higher speed of reading fixed text message (P < 0.001). Conclusion. SN6AD1 MIOL provided a satisfactory full range of visual acuities and questionnaire performance 2 years postoperatively. One-year and 2-year uncorrected near and intermediate visual acuities of SN6AD1 MIOL were lower than those 3 months postoperatively.
目的。评估SN6AD1多焦点人工晶状体（MIOL）或SN60WF人工晶状体双侧植入术后2年的视力及问卷调查结果。方法。纳入随机安排接受SN6AD1 MIOL和SN60WF人工晶状体双侧植入并进行2年随访的患者。评估未矫正/矫正的远、近视力，63厘米处高低对比度下的未矫正中视力，阅读活动，散焦曲线以及生活质量问卷。结果。每组包括20名患者。SN6AD1组的未矫正中视力和未矫正近视力优于SN60WF组（P = 0.005、P = 0.011和P < 0.001）。在SN6AD1组中，术后1年和2年的未矫正中视力和近视力分别低于术后3个月的结果。SN6AD1组报告总体上眼镜依赖程度更高且满意度更低。SN6AD1组阅读报纸的持续时间比SN60WF组更长（P = 0.036）。使用手机时，SN6AD1组的观看距离比SN60WF组更舒适（P < 0.001），阅读固定短信的速度更高（P < 0.001）。结论。SN6AD1 MIOL术后2年提供了令人满意的全方位视力及问卷调查表现。SN6AD1 MIOL术后1年和2年的未矫正近视力和中视力低于术后3个月时的水平。
