不同眼轴长度白内障患者散光矫正型人工晶状体植入术后相关指标的差异

Differences in related indicators after Toric intraocular lens implantation in cataract patients with different axial lengths

摘要:

目的：探究不同眼轴长度白内障患者散光矫正型人工晶状体(TIOL)植入术后视力恢复、角膜散光及TIOL旋转稳定性的差异。

方法：回顾性分析。选取2021-02/2022-09于我院眼科行超声乳化白内障吸除联合TIOL植入术的年龄相关性白内障合并角膜散光患者132例132眼，依据眼轴长度分为眼轴≤24mm组(79例79眼)和眼轴>24mm组(53例53眼)。术后3mo，对比两组患者最佳矫正远视力(BCDVA)、角膜散光及TIOL旋转情况。

结果：术后3mo，两组患者BCDVA均较术前改善，角膜散光度数均较术前显著降低(P<0.001)，但两组间BCDVA、角膜散光度数均无差异(P>0.05)，且两组间TIOL旋转度数也无明显差异\〖(5.24±3.72)° vs(6.36±4.21)°，P=0.110]。

结论：不同眼轴长度白内障患者TIOL植入术后视力恢复、角膜散光及TIOL旋转稳定性无明显差异。

Abstract:

AIM: To investigate the differences in visual recovery, corneal astigmatism, and rotation stability of Toric intraocular lens(TIOL)implantation in cataract patients with different axial lengths.

METHODS: Retrospective analysis. A total of 132 patients(132 eyes)with age-related cataract and corneal astigmatism who underwent phacoemulsification cataract extraction combined with TIOL implantation in our hospital's ophthalmology department from February 2021 to September 2022 were selected. They were divided into two groups based on the axial length: the group with axial length ≤24mm(79 cases, 79 eyes)and the group with axial length >24mm(53 cases, 53 eyes). Compare the best corrected distance visual acuity(BCDVA), corneal astigmatism, and TIOL rotation between the two groups of patients at 3mo after surgery.

RESULT: After 3mo of surgery, both groups of patients had improved BCDVA and significantly decreased corneal astigmatism compared to those before surgery(P<0.001). However, there was no difference in BCDVA and corneal astigmatism between the two groups(P>0.05), and there was no significant difference in TIOL rotation between the two groups \〖(5.24±3.72)° vs.(6.36±4.21)°, P=0.110\〗.

CONCLUSION: There is no significant difference in visual recovery, corneal astigmatism, and TIOL rotational stability after TIOL implantation in cataract patients with different axial lengths.
