6、选择，从而为改善患者愈后提供依据，为该类患者人群的诊治提供一定的参考价值。方法：2015年7月-2017年7月在我院手术治疗的白内障合并角膜散光患者27例(27眼)作为研究对象。收集的患者年龄在43-88岁之间，按术前角膜散光程度分为2组，A组14例，B组13例。A组为角膜散光-1.0D~-2.0D，B组为角膜散光-2.0D以上。两组均行白内障超声乳化联合Toric人工晶体植入术（TIOL）。并分类汇总各组患者的临床资料及对患者进行术后随访。调查患者术前和术后1天、7天、1月、3月、6月等六个不同时间的角膜屈光状态、术后自觉症状、最佳矫正视力、裸眼视

7、力以及散光矫正率、散光度等一般资料。针对性分析对比A组和B组超声乳化联合Toric人工晶体植入对不同程度角膜散光影响的差异，用平均值±标准差代表所得到的实验数据，借助t检验、秩和检验为手段进行统计分析，A、B两组有显著性差异时用P<0.05表示。结果：在统计学分析的基础上得出以下结论：A、B两组患者手术结束后其裸眼视力都有较为显著的变化，A、B两组患者在术后5个不同时间段内，其角膜散光和术前并未表现出显著的统计学差异，A、B两组残余散光明显减小。结论：1.对术前角膜散光度-1.0D~-2.0D的患者，白内障超声乳化联合Toric人工晶体植入术对角膜散

8、光不产生影响，裸眼视力得到提升；2.对术前角膜散光度>-2.0D的患者，白内障超声乳化联合Toric人工晶体
