摘要

目的

观察飞秒激光辅助白内障手术(femtosecond laser assisted cataract surgery

FLACS)矫正角膜规则散光的早期效果。

方法

采用前瞻性临床对照研究。选择就诊于重庆爱尔麦格眼科医院符合纳入标准的白内障合并角膜规则散光(0.75~4.00D)患者60例

分为手工组及飞秒组

每组30例(30眼)。术前测量裸眼远视力和散光量(TIA); 在术后1个月和3个月

测量裸眼远视力、残余散光量(difference vector

DV)和手术矫正散光量(surgically induced astigmatism

SIA)

由TIA和SIA计算出散光矫正指数(correction index

CI)。术后观察早期并发症

术后3个月采用问卷法比较两组远视力脱镜率。

结果

飞秒组与手工组裸眼远视力和残余散光量比较

术后1个月和3个月差异均有统计学意义(

0.05)。术后1个月与3个月的组内比较

两组裸眼远视力和残余散光量的差异均无统计学意义(

0.05)。术后3个月

飞秒组CI明显高于手工组

差异有统计学意义(

0.05)。术后3个月

飞秒组脱镜率(75.0%)与手工组(41.67%)比较

差异有统计学意义(

0.05)。

结论

相对于传统手工方法

飞秒激光辅助白内障手术矫正低、中度角膜规则散光的疗效优异

为白内障合并角膜规则散光患者增添了一种安全、有效的治疗选择。

Abstract

Objective

To observe the early efficacy of femtosecond laser assisted cataract surgery (FLACS) in astigmatism correction.

Methods

A prospective clinical control trial was performed on 60 cataract patients with regular corneal astigmatism (0.75~4.00D) admitted in Chongqing Aier Mega Eye Hospital from May 2016 to May 2017.They were divided into manual group and FLACS group

with 30 cases in each group.Uncorrected distance visual acuity and target induced astigmatism (TIA) were measured before surgery.At 1 and 3 months after surgery

uncorrected distance visual acuity

difference vector (DV) and surgically induced astigmatism (SIA) were measured

and astigmatism correction index (CI) was calculated from TIA and SIA.The early complications and rate of glass independence were observed at 3 months after surgery.

Results

There were significant differences in uncorrected distance visual acuity and DV between the FLACS group and manual group at 1 and 3 months after surgery (

0.05).Compared with each group

uncorrected distance visual acuity and DV was insignificant (

0.05) between 1 month and 3 months after surgery.In 3 months after surgery

the FLACS group had obviously higher CI (

0.05) and higher rate of glass independence (75.00%

41.67%

0.05) when compared with manual group.

Conclusion

Compared with the manual approach

FLACS shows an excellent efficacy for corneal regular astigmatism at low or moderate degree

which provides a safe and effective choice for such patients.
