摘　　要：目的观察双焦点散光型人工晶状体(ToricIOL)植入对伴有低度数角膜散光的白内障患者的屈光矫正效果。设计回顾性病例系列。研究对象伴有低度数角膜散光(0.75~1.25 D)的白内障患者40例,其中20例行超声乳化联合双焦点ToricIOL植入术者为研究组(Toric组),20例行超声乳化联合双焦点IOL植入术者为对照组。方法回顾患者病历资料,记录并比较两组患者术后的裸眼远视力(uncorrected distance visual acuity,UDVA)、最佳矫正远视力(best corrected far vision acuity,BCVA)、裸眼近视力(uncorrected near visual acuity,UNVA)、最佳矫正近视力(best corrected near vision,BCNV)、散光度和视觉生活质量评分。主要指标UDVA、BCVA、UNVA、BCNV、散光度及视觉生活质量评分。结果Toric组UDVA、UNVA均优于对照组(P均<0.05),两组间BCVA、BCNV差异无统计学意义(P均>0.05);两组患者术前散光度差异无统计学意义(P>0.05),术后3个月Toric组和对照组患者的散光均值分别为(0.31±0.12)D和(0.83±0.28)D(t=-7.634,P<0.001);两组患者主观视觉质量问卷(QoV)的总评分均为良好,Toric组总评分(88.12±0.142)优于对照组(81.77±1.15)(t=15.558,P<0.001)。光干扰评分Toric组(23.7±0.97)明显优于对照组(18.09±0.52)(t=22.756,P<0.001)。两组患者在中近距离的生活能力无明显差异,Toric组患者的夜间驾驶能力评分(4.15±0.16)明显优于对照组(2.26±0.22)(t=31.168,P<0.001)。结论双焦点ToricIOL植入可改善伴有低度数散光的白内障患者术后的角膜散光,提升患者术后裸眼远近视力水平,降低双焦点IOL的光学干扰,提升术后视觉质量。Objective To observe the refractive correction effect of bifocal Toric IOL implantation on cataract patients with low-degree of corneal astigmatism.Design Retrospective case series.Participants Forty cataract patients with low-degree corneal astigmatism(0.75~1.25 D)were enrolled.Twenty patients underwent phacoemulsification combined with bifocal Toric IOL implantation(Toric group),and 20 patients underwent phacoemulsification combined with bifocal IOL implantation(control group).Methods The patients'medical records were reviewed,and the uncorrected distance visual acuity(UDVA),the best corrected far vision acuity(BCVA),the uncorrected near visual acuity(UNVA),and the best corrected near vision(BCNV),astigmatism,and visual quality of life score were recorded and compared between the two groups.Main Outcome Measures UDVA,BCVA,UNVA,BCNV,astigmatism and visual quality of life score.Results UDVA and UNVA in Toric group were better than those in control group(all P<0.05).There was no significant difference in BCVA and BCNV between the two groups(all P>0.05).There was no significant difference in astigmatism between the two groups before surgery(P>0.05).At 3 months after surgery,the mean astigmatism was(0.31±0.12)D in the Toric group and(0.83±0.28)D in the control group(t=-7.634,P<0.001).The total score of subjective visual quality questionnaire(QoV)was good in both groups,and the total score of the Toric group(88.12±0.142)was better than that of the control group(81.77±1.15)(t=15.558,P<0.001).The light interference score of Toric group(23.7±0.97)was significantly better than that of control group(18.09±0.52)(t=22.756,P<0.001).There was no significant difference in medium and near distance living ability between the two groups.But the night driving ability score of the Toric group(4.15±0.16)was significantly better than that of the control group(2.26±0.22)(t=31.168,P<0.001).Conclusion Bifocal Toric IOL implantation can improve corneal astigmatism,uncorrected distance and near visual acuity,reduce the optical int
