摘要
目的:比较超声乳化白内障摘除联合散光型人工晶状体(Toric IOL)植入术与球面IOL植入联合角膜缘松解术矫正老年性白内障患者术前散光的疗效。方法:回顾性分析2012年本院眼科住院的老年性白内障手术患者56例56眼。按角膜散光度大小分为A组(0.75 D≤散光≤1.50 D)28眼,B组(1.75 D≤散光≤3.50 D)28眼。患者均进行超声乳化联合Toric IOL植入术和球面人工晶状体联合角膜缘松解术矫正术前散光,比较两组患者术后3个月的裸眼视力、矫正视力、柱镜度数及散光矫正率。结果:术后验光比较,两组术后3个月小瞳验光柱镜度数明显降低;A组中Toric IOL组与角膜缘松解术组的矫正视力、柱镜度数及散光矫正率比较,差异无统计学意义(P>0.05);B组中Toric IOL组术后矫正视力、柱镜度数及散光矫正率与角膜缘松解术组比较,差异有统计学意义(P<0.05);且Toric IOL植入囊袋内稳定性良好,随访3个月未发现有超过6度的旋转度。结论:Toric-IOL与角膜缘松解术两种手术方式矫正老年性白内障患者术前散光安全、有效。Toric-IOL术矫正高度数散光的疗效优于角膜缘松解术。
Objective：To compare the efficacy of the Phacoemulsification combined with the Toric IOL implantation and spherical IOL implantation used limbal relaxing for the correction of curative effect of senile cataract patients preoperative astigmatism. Method：56（56 eyes）patients with senile cataract surgery in 2012 in our hospital were retrospectively analyzed.＆amp;nbsp;According to the corneal astigmatism,they were divided into group A,0.75 D≤astigmatism≤1.50 D,28 eyes and group B, 1.75 D≤astigmatism≤3.50 D,28 eyes. Each group of patients were implanted Toric IOL and corneal limbal lysis correction of astigmatism,compared the effect by two different surgery,including naked eye vision,corrected vision,column for eyeglasses and astigmatism correction rate. Result：Postoperative optometry,after 3 months of two groups of small pupil test beams for eyeglasses significantly reduced;In the group A,Toric IOL group and corneal limbus release of vision correction, column for eyeglasses and astigmatism correction rate comparison,there were no statistically significant difference（P〉0.05）;In the group B,Toric IOL group of postoperative vision correction,column for eyeglasses and astigmatism correction rate compared with limbal release technique group,difference were statistically significant（P〈0.05）;Toric IOL implanted with good stability in pouch,followed up for 3 months more than 6 degrees of rotation had not been found. Conclusion：It is safe and effective for two kinds of surgery to correct senile cataract that have corneal astigmatism. The effect of Toric-IOL corrected the high degree astigmatism is better than corneal limbus release technique.
