目的评价AcrySof Toric SA60TT型人工晶状体(IOL)治疗白内障合并角膜散光的临床效果和应用价值.方法自身对照研究.2010年12月至2011年10月就诊的白内障合并中高度规则散光患者25例(30眼),术前测量所需植入IOL的球镜度和角膜散光度,并通过Alcon在线软件计算IOL的型号和放置轴向,行白内障超声乳化术并植入AcrySof Toric IOL,放置IOL于目标轴向.随访3个月.观察术前及术后3个月的裸眼视力、最佳矫正视力、预计术后残余散光度、实际术后残余散光度、IOL旋转度.采用配对资料t检验.结果术后1d裸眼视力为4.72±0.12,术后3个月裸眼视力为4.96±0.08.术前角膜散光为(1.80±0.45)D,预计术后残余散光为(0.29±0.16)D,术后3个月实际残余散光为(0.33±0.21)D,术前与术后相比差异有统计学意义(t=3.39,P＜0.05),预计术后残余散光与术后3个月实际残余散光比较差异无统计学意义(t=2.04,P＞0.05).术后1d20跟IOL轴位发生旋转,平均(5.50±4.07)°,术后3个月8眼无旋转,6眼轴位旋转＜2°,12眼2～5°,4眼5～10°,无一例旋转超过10°以上,平均(5.68±4.12)°.结论 AcrySof Toric IOL对白内障合并角膜散光患者有良好且稳定的治疗效果.

Objective To investigate the clinic curative effects and rotational stability of AcrySof Toric intraocular lens (IOL) for corneal astigmatism eorrection in cataract patients.Methods It was a self control study.Different types of AcrySof Toric IOL were implanted in 25 cases (30 eyes)cataract patients with more than 1 D corneal astigmatism by phacoemulsification.Preoperation IOL spherical degree was calculated by ophthalmologic A/B scan.Corneal astigmatism was measured by corneal topography.Lens type and position were calculated by Alcon formula.During the operation,the axis of the Toric lens was alingned to the steepest axis of the corneal astigmatism.Patients were followed up for 3 months.The uncorrected visual acuity,corneal astigmatism,position of the lens and cylinder power were detected and compared before and after the operation.Data were analyzed using paired t test.Results One day postoperation,the mean uncorrected visual acuity (UCVA) was (4.72±0.12).At 3 months,it was (4.96±0.08).Preoperation the mean corneal astigmatism was (1.80±0.45)D,anticipated residual astigmatism was (0.29±0.16)D,3 months postoperation residual astigmatism was (0.33±0.21)D.The difference between preoperative corneal astigmatism and postoperative residual astigmatism was significant (t=3.39,P＜0.05).And the difference between anticipated and actual residual astigmatism was not significant.The mean axis rotation of toric IOL was (5.50±4.07)° 1 day postoperation and (5.68±4.12)° after 3 months.IOL in 14 eyes had rotated less than 2°,IOL in 12 eyes had rotated 2-5°,and IOL in 4 eyes had rotated 5-10°.Conclusion Implantation of Acrysof Toric IOL for correction corneal astigmatism in cataract patients is effective and stable.
