摘　　要：目的探讨Toric人工晶状体(IOL)植入矫正白内障患者角膜散光的效果。方法回顾汉口爱尔眼科医院2008年3月到2011年3月术中植入Toric IOL的超声乳化白内障吸除术治疗白内障患者48例(60只眼),观察项目包括术前以及术后裸眼及矫正视力、散光度及术后IOL的稳定性。随访时间为术后1 d、1个月3、个月6、个月、1年。平均随访时间为7.2个月。结果术后3个月80%患者裸眼视力>0.5,68.3%患者裸眼视力>0.8。术后角膜散光由术前的(2.53±0.83)D降至(0.43±0.39)D(P<0.01),而术前预期残余散光(0.33±0.36)D相比差异无统计学意义(P=0.93)。Toric IOL术后第l天平均偏离轴位2.3°±4.3°,最后一次随访时平均旋转3.9°±6.7°。结论 Toric IOL植入矫正角膜散光效果可靠,SN60T Toric IOL具有良好的旋转稳定性,用于矫正白内障患者角膜散光安全有效。Objective To discuss the effect of TORIC intraocular lens（IOL）implantation to correct preexisting astigmatism in patients with cataract surgery.Methods This study in Wuhan Aier Eye hosipital included 60 eyes of 48 patients with more than 1.0 diopter（D）of preexisting corneal astigmatism with cataract surgery.The uncorrected visual acuity（UCVA）,best corrected visual acuity（BCVA）.residual cylinders,and TORIC IOL axis were measured at 1 d,1 month,3 months,6 months and 1year preoperatively.The average follow-up time was 7.2months.Results The UCVA was 0.5 or better in 80%of eyes and 0.8 or better in 68.3% case.The mean refractive cylinder decreased significantly after surgery from（2.53±0.83）D to（0.43 ±0.39）D（P0.01）,which was statistically significance with anticipated residual cylinder（0.33±0.36）D（P=0.94）.The mean TORIC IOL axis rotation was 2.3±4.3°at l d postoperatively and 3.9±6.7°at the last follow up time.Conclusion The SN60TT TORIC IOL showed good stability.Phacoemulsification and posterior chamber TORIC IOL implantation is an safe and effective option to correct preexisting astigmatism in cataract patients.
