摘　　要：目的 评估AcrySof散光型人工晶状体（AcrySof（R） Toric IOL）矫正白内障患者术前角膜散光的有效性及安全性.方法 收集厦门大学附属厦门眼科中心角膜散光＞0.75D的年龄相关性白内障患者36例42只眼.按随机化原则将患者分为A、B两组,A组（15例18只眼）植入AcrySof（R） Toric IOL,B组（21例24只眼）植入AcrySof（R） Natural IOL.观察术后1周、1个月、3个月裸眼远视力、最佳矫正远视力、残余柱镜散光、AcrySof（R） Toric IOL轴位旋转稳定性、术前术后角膜散光对比情况,以及术后问卷形式调查远视脱镜率及满意度.结果 术后1周、1个月、3个月裸眼远视力≥0.8者,A组分别占66.7%（12/18）、72.2%（13/18）、72.2%（13/18）;B组分别占33.3%（8/24）、37.5%（9/24）、37.5%（9/24）,两组比较差异有统计学意义（P ＜0.05）.最佳矫正远视力≥0.8者,两组差异无统计学意义（P ＞0.05）.A、B两组术前与术后3个月角膜散光度数分别比较,均无统计学意义（P ＞0.05）.术后1周、1个月、3个月平均残余散光度数,A组分别为（0.66±0.48）D、（0.74±0.35）D、（0.73±0.34）D;B组分别为（1.57±1.03）D、（1.42±0.67）D、（1.35±0.53）D,差异有统计学意义（P ＜0.05）.术后3月AcrySof（R） Toric IOL平均离轴旋转＜5°.远视脱镜率：A组为72.2%（13/18）,B为37.5%（9/24）,差异有统计学意义.A组视物满意度为77.8%（14/18）,高于B的41.7%（10/24）,差异有统计学意义.两组术后无明显视觉不良症状及并发症.结论 AcrySof（R） Toric IOL是矫正白内障患者术前角膜散光的一种有效方式,并且其具有良好地轴位旋转稳定性.AcrySof（R） Toric IOL与普通人工晶状体相比可明显改善白内障患者的术后远视力,并降低术后戴镜率.Objective To evaluate the safety and efficacy of AcrySof（R） Toric intraocular lens implantation to correct preexisting corneal astigmatism in cataract surgery. Methods Thirty-six cataract patients （42 eyes） with corneal astigmatism greater than 0.75D were involved in this study and randomized divided into two groups. Group A with 15 patients （18 eyes） received AcrySof（R） Toric IOL implantation and group B with 21 patients （24 eyes） received AcrySof（R） Natural IOL after phacoemulsification. Uncorrected distant visual acuity （UCDVA）, best corrected distant visual acuity （BCDVA）, corneal astigmatism, residual astigmatism, Toric IOL rotational stability, spectacles independence, patient satisfaction and operative complications were observed. Results Patients with UCDVA 0.8 or better accounted for 66.7% （12/18）, 72.2% （13/18）, 72.2% （13/18） in group A and 33.3% （8/24）, 37.5% （9/24）, 37.5% （9/24） in group B, respectively. There were significant differences between the two groups 1 week, 1 month and 3 months after operation （P 〈0.05）. There was no statistically significant difference in BCDVA between the two groups （P 〉0.05）. There were no significant differences in preoperative corneal astigmatism and corneal astigmatism 3 months after operation in the two groups respectively （P 〉0.05）. There were significant differences in the mean residual astigmatisms between the two groups 1 week, 1 month and 3 months postoperatively （P 〈0.05）. The mean Toric IOL axis rotation was less than 5 degrees 3 months postoperatively. Spectacles were not necessary in 72.2% （13/18） and 37.5% （9/24） cases in group A and B, respectively. No eye had intraoperative or postoperative complications. Conclusions The results indicate that AcrySof（R） Toric IOL implantation is an effective option to correct preexisting corneal astigmatism in cataract surgery. The Toric IOL shows good rotational stability.
