To evaluate visual outcome, reading performance, contrast sensitivity, and patient satisfaction after cataract surgery with implantation of a diffractive trifocal intraocular lens (IOL).
A total of 42 eyes (21 patients) underwent cataract surgery with implantation of the trifocal IOL AT LISA tri 839MP. Visual acuity, contrast sensitivity, and patient satisfaction were evaluated 3 months postoperatively. Reading performance was evaluated at 3 months postoperatively with the MNREAD charts.
All eyes achieved a 3-month postoperative monocular uncorrected distance visual acuity of 0.10 logMAR or better (Snellen 20/25). Likewise, 97.62% and 85.71% of eyes achieved a postoperative monocular uncorrected intermediate, and near visual acuity of 0.20 logMAR (Snellen 20/30) or better. All patients achieved postoperative binocular uncorrected distance visual acuity, uncorrected intermediate, and uncorrected near visual acuity of 0.20 logMAR (Snellen 20/30) or better. Mean photopic reading acuity and speed were 0.24±0.07 logMAR and 177.61±20.67 words per minute, respectively. Postoperative contrast sensitivity values were within the ranges of normality for all spatial frequencies evaluated. Postoperative spectacle independence and patient satisfaction was very high, with most of the patients reporting a good or very good visual quality at far, intermediate, and near distances. All patients would choose the same lens again.
The evaluated trifocal IOL provides an effective restoration of the visual function after cataract surgery, with high levels of distance, intermediate, and near visual acuity, strong reading performance, and patient satisfaction.
评估植入衍射型三焦点人工晶状体（IOL）的白内障手术后的视觉效果、阅读能力、对比敏感度和患者满意度。
共有42只眼（21例患者）接受了植入三焦点IOL AT LISA tri 839MP的白内障手术。术后3个月评估视力、对比敏感度和患者满意度。术后3个月使用MNREAD图表评估阅读能力。
所有术眼术后3个月的单眼未矫正远视力均达到0.10 logMAR或更好（Snellen 20/25）。同样，97.62%和85.71%的术眼术后单眼未矫正中视力和近视力达到0.20 logMAR（Snellen 20/30）或更好。所有患者术后双眼未矫正远视力、未矫正中视力和未矫正近视力均达到0.20 logMAR（Snellen 20/30）或更好。平均明视阅读视力和速度分别为0.24±0.07 logMAR和177.61±20.67字/分钟。术后所有评估空间频率的对比敏感度值均在正常范围内。术后摆脱眼镜的情况和患者满意度非常高，大多数患者报告在远、中、近距离的视觉质量良好或非常好。所有患者都愿意再次选择同一晶状体。
所评估的三焦点IOL在白内障手术后能有效恢复视觉功能，具有高水平的远、中、近视力，较强的阅读能力和患者满意度。
