三焦点人工晶状体植入术对白内障患者疗效观察

Clinical outcomes of a trifocal intraocu-lar lens

目的研究超声乳化白内障摘除植入三焦点人工晶状体(IOL)术后患者的视觉质量。方法前瞻性非随机对照研究。收集2016年11月至2017年6月收治的28例(56眼)行超声乳化白内障吸除术的白内障患者分为两组,SIOL组14例(28眼)植入单焦人工晶状体(AcrySof IQ),TIOL组14例(28眼)植入三焦点人工晶状体(AT LISA tri 839MP),术后6月时观察两组患者的裸眼远、中、近视力,最佳矫正远、中、近视力及问卷调查术后患者主观全程视力的满意度。结果TIOL组患者的裸眼近视力、裸眼中视力高于SIOL组,差异有统计学意义(P<0.05),而裸眼远视力及矫正远、中、近视力差异无统计学意义(P>0.05)。问卷调查结果显示TIOL组在脱镜率及中、近视力满意度均高于SIOL组,差异有统计学意义(P<0.05),远视力及IOL总体满意度差异无统计学意义(P>0.05)。结论植入三焦点人工晶状体后可提供极好的远、中和近视力,值得临床推广应用。

Objetive To observe the clinical effect of trifocal IOLs implantation in the treatment of cataract. Methods Twenty eight patients （56 eyes）with age-related cataract were divided into two groups： AcrySof IQ IOL were implanted into sinfocal IOL group（SIOL group） ,and AT LISA tri 839MP were implanted into trifocal IOLs group（TIOL group）.Uncorrected and corrected distant vision, middle vision, near visual acuity were measured at 6 month postoperatively, and patients questionnaires were evaluated. Result Six months after the surgery, the TIOL group obtained better performances at uncorrected middle vision and near vision （ P 〈 0.05 ） . There was no statistical difference in uncorrected distant vision and corrected distant vision, intermediate vision, near vision （P〉0.05）. The TIOL group obtained better satisfaction score of near and intermediate visual acuity and the rate of spectacle glass independent （P〈 0.05 ）. No significant difference was observed among satisfaction of distance visual acuity and overall satisfaction（P〉0.05）. Conclusion trifocal IOLs provides excellent distance, intermediate and near visual outcomes and can be a good choice in treatment of cataract.
