FLACS-IOL手术对白内障患者术后MIOL的偏移率及视觉质量的影响

目的：探讨飞秒激光辅助超声乳化手术联合人工晶状体植入(FLACS-IOL)对白内障患者术后多焦点人工晶状体(MIOL)偏移率及视觉质量的影响。

方法：前瞻性研究。选取我院2021-01/2022-12收治的白内障MIOL植入患者95例108眼，根据患者意愿选择手术方式并分组为FLACS组(51例56眼)，Phaco组(44例52眼)。对比两组手术时间、前囊切开直径、有效超声时间(EPT)、超声乳化能量释放量(CDE)、裸眼远视力(UCDVA)、最佳矫正远视力(BCDVA)、术后3 mo的IOL偏心距离、偏移率及3 mm瞳孔下全眼总高阶像差(HOA)、三叶草差(Trefoil)及彗差(Coma)。

结果：FLACS组手术时间明显短于Phaco组，EPT、CDE均明显低于Phaco组(均P<0.05)； 两组前囊切开直径无差异(P>0.05)。FLACS组UCDVA在术后1 wk，3 mo优于Phaco组(均P<0.05)； 两组术后1 wk，3 mo的UCDVA和术后3 mo的BCDVA比较均有差异(P<0.05)。术后3 mo，FLACS组IOL偏心距离小于Phaco组，偏移率明显低于Phaco组(均P<0.05)。在3 mm瞳孔直径下，两组术后3 mo的全眼HOA、三叶草差及彗差均较术前减少(P<0.05)，FLACS组术后3 mo的全眼HOA、三叶草差与Phaco组比较均有差异(P<0.05)，FLACS组术后3 mo的彗差与Phaco组比较无差异(P>0.05)。

结论：FLACS-IOL手术可有效降低白内障患者术后IOL偏移率，获得更好的视觉质量。

Effects of femtosecond laser-assisted cataract surgery combined with intraocular lens implantation on postoperative deviation rate of multifocal intraocular lens and visual quality in cataract patients

AIM: To explore the effects of femtosecond laser-assisted cataract surgery combined with intraocular lens implantation(FLACS-IOL)on postoperative deviation rate of multifocal intraocular lens(MIOL)and visual quality in cataract patients.

METHODS: In the prospective study, 95 patients with cataract(108 eyes)who underwent MIOL implantation in the hospital between January 2021 and December 2022 were enrolled. According to different surgical methods, they were divided into FLACS group(51 cases, 56 eyes)and Phaco group(44 cases, 52 eyes). The operation time, incision diameter of anterior capsule, effective phaco time(EPT), cumulative dissipated energy(CDE), uncorrected distance visual acuity(UCDVA), best corrected distance visual acuity(BCDVA), eccentricity distance of IOL and deviation rate at 3 mo after surgery, total high order aberration(HOA), Trefoil and coma under 3 mm pupil were compared between the two groups.

RESULTS: The operation time in the FLACS group was significantly shorter than that in the Phaco group, EPT and CDE were significantly lower than those in the Phaco group(all P<0.05). There was no significant difference in incision diameter of anterior capsule between the two groups(P>0.05). At 1 wk, 3 mo after surgery, UCDVA in the FLACS group was better than that in the Phaco group(all P<0.05). There were significant difference in UCDVA at 1 wk, 3 mo after surgery or BCDVA at 3 mo after surgery between the two groups(P<0.05). At 3 mo after surgery, eccentricity distance of IOL in the FLACS group was shorter than that in the Phaco group, and deviation rate was significantly lower than that in the Phaco group(all P<0.05). Under pupil diameter of 3 mm, HOA, trefoil and coma of whole eyes were decreased in both groups at 3 mo after surgery(P<0.05). At 3 mo after surgery, there were significant differences in HOA and trefoil of whole eyes between the FLACS group and Phaco group(P<0.05), but there was no significant difference in coma at 3 mo after surgery(P>0.05).

CONCLUSION: FLACS-IOL can effectively reduce deviation rate of IOL and obtain better visual quality in cataract patients.
