目的:评价白内障超声乳化吸除联合双焦点Toric人工晶状体(IOL)植入术的散光矫正临床效果。
方法:回顾性分析。纳入2020-08/2021-09间我院白内障超声乳化吸除联合双焦点Toric IOL治疗白内障合并角膜规则散光患者46例46眼的临床资料。术后随访3mo,评价术前及术后1、3mo裸眼远视力(UDVA)、裸眼近视力(UNVA)、矫正远视力(BCDVA)、矫正近视力(BCNVA)及散光的变化。测量并计算IOL轴位旋转度,行问卷调查在不同距离使用眼镜的必要性以及总体满意度。
结果:术后1、3mo UDVA、BCDVA、UNVA、BCNVA与术前比较均有差异(均P<0.001),而术后1mo UDVA、BCDVA、UNVA、BCNVA与术后3mo比较均无差异(均P>0.0167)。术后3mo UDVA达到0.20(LogMAR)者46眼(100%),UNVA达到0.20(LogMAR)者40眼(87%)。散光矢量分析显示,术前角膜散光均值为1.88±0.70D,质心值为0.61D@177°±1.93D,术后3mo残余散光均值为0.33±0.30D,质心值为0.03D@ 34°±0.45D。术后3mo IOL轴位旋转度为3°(0°,5°)。只有5例(11%)患者要求对近距离或中距离进行一定程度的屈光矫正。83%(38例)对手术结果感到满意或非常满意。
结论:白内障术中植入双焦点Toric IOL能有效矫正术眼的角膜规则散光,提高裸眼远近视力,患者满意度高。

[Abstract]
AIM: To assess the astigmatism-correcting efficiency and clinical effects of cataract phacoemulsification combined with bifocal Toric intraocular lens(IOL)implantation.
METHODS: Retrospective analysis. The clinical data of 46 patients(46 eyes)with cataract complicated with regular corneal astigmatism by the treatment of cataract phacoemulsification and bifocal Toric IOL implantation in our hospital from August 2020 to September 2021 were included. The patients were followed up for 3mo after operation, and the changes of uncorrected distant visual acuity(UDVA), uncorrected near visual acuity(UNVA), best corrected distant visual acuity(BCDVA), best corrected near visual acuity(BCNVA)and astigmatism before and 1, 3mo after operation were evaluated. The IOL axial rotation was measured and calculated, and a questionnaire was conducted to investigate the necessity of using glasses at different distances and overall satisfaction.
RESULTS:After operation at 1 and 3mo, there were significant differences in UDVA, BCDVA, UNVA and BCNVA compared with those before operation(all P<0.001), and there was no significant difference in UDVA, BCDVA, UNVA and BCNVA at 1mo after operation and 3mo after operation(all P>0.0167). At 3mo after operation, 46 eyes(100%)of UDVA reached 0.20(LogMAR), 40 eyes(87.0%)of UNVA reached 0.20(LogMAR). Astigmatism vector analysis showed that the mean preoperative corneal astigmatism in this group was 1.88±0.70D, and the centroid value was 0.61D@177°±1.93D, the mean residual astigmatism at 3mo postoperatively was 0.33±0.30D, and the centroid value was 0.03D@34°±0.45D. After operation at 3mo, the axial rotation of IOL was 3°(0°, 5°). Only 5 eyes(11%)required some degree of refractive correction for near or intermediate distances. 83%(38 eyes)were satisfied or very satisfied with the surgical results
CONCLUSION: The implantation of bifocal Toric IOL during cataract surgery could effectively correct corneal regular astigmatism, improve uncorrected distance and near vision, and had high patient satisfaction.
