白内障超声乳化联合植入Toric人工晶状体术后疗效

Postoperative efficacy of cataract phacoemulsification combined with implantation of Toric intraocular lens

目的:探讨对伴有角膜散光的单纯白内障患者行白内障超声乳化联合植入Toric人工晶状体后,患者的视力、残余散光、人工晶状体偏转度等情况。方法:采用回顾性分析研究方法。选取2015年12月至2017年6月于解放军南京总医院行白内障超声乳化联合散光纠正型人工晶状体植入术的45例患者,术眼47只。分别测量患者术前的裸眼视力、最佳矫正视力、角膜散光度数以及手术后3个月的裸眼视力、最佳矫正视力、残余散光度数、人工晶状体偏移度数等。结果:47例眼均手术成功。术前患者的裸眼视力为0.71±0.33(log MAR),最佳矫正视力为0.44±0.34;术后3个月,患者裸眼视力为0.25±0.17(log M A R),最佳矫正视力为0.17±0.16(log M A R),差异有统计学意义(P<0.01)。术前患者角膜散光为(2.82±0.73)D;术后3个月,患者的残余散光度数为(0.41±0.26)D,较术前明显降低,差异有统计学意义(P<0.05)。术后3个月,患者人工晶状体轴向的偏转度为(3.18±2.06)°。结论:使用Toric人工晶状体治疗伴有角膜散光的白内障安全有效,术后可明显提高患者术后裸眼视力,术后残余散光度数小,可提高患者视觉质量。

Objective： To explore the vision, astigmatism, intraocular lens deflection and visual quality of cataract patients with corneal astigmatism after cataract phacoemulsification combined with Toric intraocular lens implantation. Methods： A retrospective systematic study method was used. From December 2015 to June 2017, a total of 45 patients（47 eyes） underwent cataract phacoemulsification combined with Toric intraocular lens implantation in Nanjing General Hospital. Uncorrected visual acuity（UCVA）, best corrected visual acuity（BCVA） and astigmatism were measured before and 3 months after the operation. The intraocular lens axial was measured at 3 months after operation. Results： The surgery was successfully performed in 47 patients. The UCVA before operation was 0.71±0.33（logMAR）, the BCVA was 0.44±0.34（logMAR）; at 3 months after the operation, the UCVA was 0.25±0.17（logMAR）, the BCVA was 0.17±0.16（logMAR）, and the difference was statistically significant（P〈0.01）. The astigmatism before operation was（2.82±0.73） D. The residual astigmatism at 3 months after operation was（0.41±0.26） D, which was significantly lower than that before operation（P〈0.05）; at 3 months after the operation, the axial deflection of the intraocular lens was（3.18±2.06）°. Conclusion： It is safe and effective to treat cataract patients with corneal astigmatism with Toric intraocular lens. After operation, it can significantly improve postoperative visual acuity and residual astigmatism of patients.
