目的：观察飞秒激光辅助白内障手术联合三焦点人工晶状体(IOL)植入术后的临床疗效。

方法：回顾性自身前后对照研究。选择2016-09/2017-11就诊于山西省眼科医院植入三焦点IOL的白内障患者42例59眼，随访至术后6mo，分别观察术前、术后1wk，1、3、 6mo单眼裸眼远、中、近距离视力(LogMAR)、离焦曲线、屈光稳定性、高阶像差、患者满意度和脱镜率。

结果：所有患者在术后各随访时间点远、中、近距离均可获得优于0.1LogMAR的良好视力，术后各距离视力与术前相比显著提高(P<0.05)。术后6mo离焦曲线在0～-2.5D之间曲线过渡平缓，术眼达到优于0.8的视力水平。术后6mo，63%(37眼)的患眼SE位于±0.25D之间，88%(52眼)的患眼SE则位于±0.50D之间。术后各时期全眼的总高阶像差、彗差、球差、三叶草像差明显低于术前(P<0.05)。

结论：飞秒激光辅助白内障手术联合三焦点IOL植入术可以为患者提供舒适自然的全程视力，实现真正的脱镜，患者术后满意度高。

METHODS:From September 2016 to November 2017, 42 cases(59 eyes)of cataract patients receiving trifocal IOL implantation in Shanxi Eye Hospital were retrospectively enrolled in this study. Moreover, the visual and refractive outcomes, defocus curve, refractive stability, high order aberrations, patient satisfaction, and spectacle independence were evaluated at 1wk, 1mo, 3mo and 6mo after surgery, respectively.

RESULTS: All patients had attained good visual acuity of >0.1 LogMAR at different distances during the follow-up period; besides, the visual acuity at each distance was remarkably higher compared with that before surgery(P<0.05). The defocus curve had displayed no significant decrease between 0D to -2.5D at 6mo postoperatively, with the visual acuity better than 0.8. At 6mo postoperatively, 63%(37 eyes)eyes had a spherical equivalent(SE)of ±0.25D, and 88%(52 eyes)eyes had a SE of ±0.50D. The incidences of high order aberrations, coma, spherical aberration and trefoil of all eyes were evidently lower than those before surgery, and the difference was statistically significant(P<0.05).

CONCLUSION: Femtosecond laser-assisted cataract surgery combined with trifocal IOL implantation can provide patient with a comfortable and natural full-range vision, which can greatly improve the postoperative satisfaction of patients.
