目的：观察PanOptix三焦点人工晶状体(TFNT00)植入术后的视觉质量与立体视觉。

方法：前瞻性临床研究。选取2022-11/2024-04在济南明水眼科医院行白内障超声乳化联合TFNT00植入的白内障患者36例50眼，随访至术后3 mo，观察术后裸眼远视力(UCDVA)、裸眼中距离视力(UCIVA)、裸眼近距离视力(UCNVA)、客观散射指数(OSI)、调制传递函数截至频率(MTF-cut-off)、斯特列尔比(SR)及100%、20%、9%对比度视力(CVA)等指标； 使用双目视力仪采集患者远用立体视锐度及近用立体视锐度； 绘制术后离焦曲线； 使用中文版VF-14视功能指数量表评价视觉质量与满意度。

结果：患者UCDVA、UCIVA、UCNVA在术后不同时间比较有差异(均P<0.05)。术后离焦曲线在+0.5--3.0 D之间曲线过渡平缓； 术后3 mo OSI值明显低于术前(P<0.01)，MTF-cut-off、SR、100% CVA、20% CVA、9% CVA均明显高于术前(均P<0.01)。术前34例患者远近立体视锐度异常，双眼手术患者术后远立体视锐度均正常，12例近用立体视锐度正常； 单眼手术患者中13例远用立体视锐度正常，11例近用立体视锐度正常，双眼手术患者远近立体视锐度明显优于单眼手术患者。

结论：PanOptix三焦点人工晶状体可以为患者提供良好的全程视力，双眼植入的患者立体视觉优于单眼植入的患者，患者术后整体视觉质量及满意度较高。

METHODS: A prospective clinical study was conducted. A total of 36 cataract patients(50 eyes)who underwent phacoemulsification combined with TFNT00 implantation in Jinan Mingshui Eye Hospital from November 2022 to April 2024 were selected. They were followed up until 3 mo after the operation. The uncorrected distance visual acuity(UCDVA), uncorrected intermediate visual acuity(UCIVA), uncorrected near visual acuity(UCNVA), objective scatter index(OSI), modulation transfer function cut off(MTF-cut-off), Strehl ratio(SR)and 100%, 20%, 9% contrast visual acuity(CVA)were observed. The binoptometer was used to collect the patients' far and near stereopsis acuities. The defocus curve was drawn after the operation; the Chinese version of the VF-14 Visual Function Index Scale was used to evaluate the visual quality and satisfaction after the operation.

RESULTS: There were statistically significant differences in the UCDVA, UCIVA and UCNVA of the patients at different time after the operation(all P<0.05). The transition of the defocus curve was gentle between +0.5--3.0 D after the operation. The OSI value at 3 mo postoperatively after the operation was significantly lower than that before the operation(P<0.01), and the MTF-cut-off, SR, 100% CVA, 20% CVA and 9% CVA were significantly improved than those before operation(all P<0.01). The far and near stereopsis acuities of 34 patients were abnormal before the operation. The far stereopsis acuities of the patients who underwent bilateral eye surgeries were all normal after the operation, and the near stereopsis acuity of 12 patients was normal. Among the patients who underwent unilateral eye surgeries, the far stereopsis acuities of 13 patients were normal, and the near stereopsis acuities of 11 patients were normal. The far and near stereopsis acuities of the patients who underwent bilateral eye surgeries were significantly better than those patients who underwent unilateral eye surgeries.

CONCLUSION: The PanOptix trifocal intraocular lens can provide patients with good full-range visual acuity. The stereopsis of the patients with bilateral implants is better than that of the patients with unilateral implants. The overall visual quality and satisfaction of the patients after the operation are relatively high.
