方法：选取2018-06/2020-12在佛山爱尔眼科医院接受飞秒激光辅助白内障超声乳化手术联合植入三焦点IOL的高度近视白内障患者32例38眼，比较术前，术后1wk，3mo裸眼远视力(UCDVA)、中距离视力(UCIVA)、近距离视力(UCNVA)； 术前，术后1wk，3mo进行OPD-Scan Ⅲ型像差分析仪检查。

结果：术前，术后1wk，3mo UCDVA、UCIVA、UCNVA比较均有差异(P<0.05)，术后3mo人工晶状体偏心距为0.12(0.08～0.15)mm，轴位为(212.68±90.45)°。术前，术后1wk，3mo球差比较有差异(P<0.05)。术前，术后1wk，3mo斯特列尔比(SR)、调制传递函数(MTF)曲线中4mm面积比(AR)比较均有差异(P<0.001)。术后1wk，3mo SR比术前提升，术后1wk，3mo AR比术前提升(均P<0.001)。术后3mo SR与球差、三叶草呈负相关(r_s=-0.420、-0.418，均P<0.01)； 术后3mo AR与三叶草呈负相关(r_s=-0.400，P<0.05)。

结论：高度近视合并白内障患者植入三焦点IOL术后全程视力提高，OPD-Scan Ⅲ型像差分析仪结果显示术后IOL居中性良好，视觉质量良好。

METHODS: Totally 32 patients(38 eyes)with high myopia complicated with cataract who underwent femtosecond laser assisted cataract phacoemulsification combined with trifocal intraocular lens implantation in Foshan Aier Eye Hospital from June 2018 to December 2020 were selected. Uncorrected distance visual acuity(UCDVA), uncorrected intermediate visual acuity(UCIVA)and uncorrected near visual acuity(UCNVA)were compared before, and 1wk, 3mo after surgery; OPD-Scan Ⅲ aberration analyzer measured objective visual quality before, and 1wk and 3mo after surgery.

RESULTS: There were significant differences in UCDVA, UCIVA and UCNVA before, and 1wk, 3mo after operation(P<0.05). The average orientation and centration distance was 0.12(0.08-0.15)mm and the average axial was(212.68±90.45)°in 3mo postoperative. There were significant differences in spherical aberration(P<0.05), Strehl ratio(SR)and area ratio(AR)before, and 1wk, 3mo after operation(P<0.001). In comparison, SR at 1wk and 3mo postoperative was higher than that before operation, whereas AR in 1wk and 3mo postoperative were both higher than that before operation(all P<0.001). There was a negative correlation between SR and spherical aberration at 3mo postoperative(r_s=-0.420, P<0.01); There was a negative correlation between SR and trefoil at 3mo postoperative(r_s= -0.418, P<0.01); There was a negative correlation between AR and trefoil at 3mo postoperative(r_s=-0.400, P<0.05).

CONCLUSION: Femtosecond laser assisted cataract surgery combined with trifocal intraocular lens implantation can provide a comfortable and natural full-range vision. The orientation and centricity of trifocal intraocular lens using OPD-Scan Ⅲ has shown that there was a good reliability and consistency. The vision quality using OPD-Scan Ⅲ is satisfactory.
