飞秒激光辅助超声乳化吸除联合多焦点IOL植入术治疗白内障

目的：探讨飞秒激光辅助超声乳化吸除联合多焦点IOL植入术治疗白内障的临床价值。

方法：将2015-07/2018-07收治的94例94眼白内障患者以随机数字表法分为观察组47例47眼，对照组47例47眼，观察组行飞秒激光辅助超声乳化吸除联合多焦点IOL植入术治疗，对照组行传统超声乳化吸除联合多焦点IOL植入术治疗，对两组手术相关指标、角膜内皮细胞密度、视力情况及并发症进行观察。

结果：观察组超声乳化时间较对照组短，超声能量、术中超声乳化累积能量复合参数及术后7d前房闪辉值均低于对照组(P<0.05)。术前两组角膜内皮细胞密度无差异(P>0.05)，术后3mo观察组角膜内皮细胞密度较对照组高(P<0.05)。术前两组BCVA、UCVA无差异(P>0.05)，术后3mo观察组BCVA及UCVA均优于对照组(P<0.05)。两组并发症无差异(P>0.05)。

结论：飞秒激光辅助超声乳化吸除联合多焦点IOL植入术治疗白内障临床效果明显，能减少超声累积释放能量，减轻角膜内皮损伤，促进患者视力恢复，安全性高。

Femtosecond laser-assisted phacoemulsification combined with multifocal intraocular lens implantation in the treatment of cataract

AIM: To probe into the clinical values of femtosecond laser-assisted phacoemulsification combined with multifocal intraocular lens implantation in the treatment of cataract.

METHODS: Totally 94 cases(94 eyes)of patients with cataract and who treated from July 2015 to July 2018 were divided into observation group(47 eyes)and control group(47 eyes)by random number table method. The observation group wes received femtosecond laser-assisted phacoemulsification combined with multifocal intraocular lens implantation, while the control group were received traditional phacoemulsification combined with multifocal intraocular lens implantation Then, the operation related indexes, corneal endothelial cell density, visual acuity and complications of two groups were observed.

RESULTS:The time of phacoemulsification in the observation group was shorter than that in the control group, and the ultrasound energy, cumulative energy of intraoperative phacoemulsification and anterior chamber flash value after operation for 7d were lower than those in the control group(P<0.05). There was no significant difference in corneal endothelial cell density between the two groups before operation(P>0.05). The corneal endothelial cell density after operation for 3mo in the observation group was significantly higher than that in the control group(P<0.05). There was no significant difference in the best corrected visual acuity(BCVA)and uncorrected visual acuity(UCVA)between the two groups(P>0.05). The BCVA and UCVA after operation for 3mo in the observation group were better than those in the control group(P<0.05).There was no significant difference in complications between the two groups(P>0.05).

CONCLUSION: The effects of femtosecond laser-assisted phacoemulsification combined with multifocal intraocular lens implantation in treatment of cataract are significant, which can reduce the cumulative release of ultrasound energy, reduce corneal endothelial damage, and promote visual recovery of patients, thus it is safe and it is worthy to be promoted.
