摘　　要：目的:通过一种高精度方法评价AcryS of散光型人工晶体的旋转稳定性。方法:收录90例年龄相关性白内障伴中、高度散光患者(104眼),施行白内障超声乳化联合AcryS of散光型人工晶体植入术。患者在规定的复查时间接受必要的检查。通过KR-1W视觉质量分析仪检测AcryS of散光型人工晶体的稳定性。观察指标包括裸眼远视力(UDVA)、最佳矫正远视力(CDVA)以及显然验光结果。通过配对T检验及ANOVA检验分析结果。结果:研究共纳入104眼,从术前检查至最后一次术后复查持续24个月。7次复查时间点观察到AcryS of散光型人工晶体的位置没有显著变化,P=0.863;所有患者的裸眼远视力(logM AR,4.39±0.27至4.77±0.22;P<0.001)、最佳矫正远视力(logM AR,4.54±0.25至4.93±0.14;P<0.001)以及显然验光[度(D),-1.27±0.98至-0.97±0.71,P=0.003]均有显著改善。术后调制传递函数(MTF)较术前提高。结论:研究显示AcryS of散光型人工晶体具有很好的旋转稳定性。该种人工晶体可以减少显然验光的柱镜度数、提高视力并改善视力相关的生活质量。AIM：To evaluate the rotational stability of AcrySof toric intraocular lens（IOL） after cataract surgery,by an highprecision method.METHODS：A total of 104 eyes of 90 patients with age related cataract and moderate to high regular astigmatism underwent phacoemulsification and implantation of AcrySof toric IOL（SN6AT series;Alcon,Fort Worth,TX,USA）.Patients underwent comprehensive examinations at standard intervals.The rotational stability of AcrySof toric intraocular lens was evaluated using visual quality analyser KR-1W（Topcon,Tokyo,Japan）.Uncorrected distance visual acuity（UDVA）,corrected distance visual acuity（CDVA） and manifest refraction were also recorded.The outcomes were analysed by paired-samples T test and ANOVA Test.RESULTS：From preoperatively to the last visit（24mo）,104 eyes were included in the clinical trial.The AcrySof toric IOL axis orientation（at seven visits） did not show significant change,P = 0.863.All of the eyes had significant improvement in UDVA（logMAR,4.39±0.27 to4.77±0.22;P〈0.001）,CDVA（logMAR,4.54±0.25 to 4.93±0.14;P〈0.001） and manifest refraction astigmatism[diopters（D）,-1.27±0.98 to-0.97±0.71,P=0.003].There was an increase in MTF results between preoperative and postoperative evaluations.CONCLUSION：The AcrySof toric IOL shows good rotational stability.It can reduce manifest refraction cylinder and improve visual acuity and vision- related quality of life permanently.
