飞秒激光白内障手术联合PanOptix三焦点人工晶状体植入术的疗效

目的:观察飞秒激光白内障手术联合PanOptix三焦点人工晶状体植入术的临床疗效。方法:回顾性研究。选取2020-08/2021-08于我院行飞秒激光白内障手术联合PanOptix三焦点人工晶状体植入术的白内障患者22例26眼，随访至术后3mo,观察手术前后远中近视力、像差、斯特里尔比值(SR)及调制传递函数截止频率(MTF-cutoff)变化情况，绘制术后1mo离焦曲线，评估术后3mo患者视觉质量和满意度。结果:术后1d, 1wk, 1、3mo,纳入患者远中近视力均优于0.1(LogMAR),与术前相比显著改善(均P<0.01)。术后1mo离焦曲线在+0.5～-3.0D之间曲线过渡平缓，视力均优于0.63(小数视力)。术后1d, 1wk全眼总像差、球差均明显低于术前，SR、MTF-cutoff均明显高于术前(均P<0.05)。术后3mo,纳入患者看远中近距离时均无需戴镜，整体满意度高，视觉质量良好。结论:飞秒激光白内障手术联合PanOptix三焦点人工晶状体植入术可使患者获得舒适满意的全程视力。

Clinical efficacy of femtosecond laser-assisted cataract surgery combined with PanOptix trifocal intraocular lens implantation

AIM: To evaluate the clinical efficacy of femtosecond laser-assisted cataract surgery combined with PanOptix trifocal intraocular lens implantation.

METHODS:The retrospective study enrolled 22 cases(26 eyes)of cataract patients who underwent femtosecond laser-assisted cataract surgery combined with PanOptix trifocal intraocular lens implantation from August 2020 to August 2021. Follow-up to 3mo after surgery, the changes of far, intermediate and near visual acuity, aberration, Strehl ratio(SR)and modulation transfer function cutoff(MTF-cutoff)frequency were compared. Defocus curve at 1mo postoperatively was made, and the visual quality and satisfaction were evaluated after 3mo of surgery.

RESULTS: The visual acuity of all patients was better than 0.1(LogMAR)at the far, intermediate and near distance at 1d, 1wk, 1 and 3mo postoperatively, and it was significantly improved compared with those before surgery(all P<0.01). The defocus curve transitioned smoothly between +0.5 and -3.0D at 1mo after surgery, and visual acuity was better than 0.63. The total aberration and spherical aberration in the whole eye were significantly lower after surgery than before, and the SR and MTF-cutoff were significantly improved at 1d and 1wk after surgery(all P<0.05). With high satisfaction and good visual quality, patients could watch at far, intermediate and near distance without wearing glasses at 3mo after surgery.

CONCLUSION: Femtosecond laser-assisted cataract surgery combined with PanOptix trifocal intraocular lens implantation gave patients a comfortable and satisfactory full-course vision.
