3、联合非球面人工晶状体植入术后视觉质量的临床研究摘要目的:探讨并观察3.0mm小切口白内障手法碎核摘除(MSCS)和超声乳化摘除(Phaco)联合人工晶状体植入术的手术方法及术后视觉效果。方法:选择156例(190只眼)白内障患者,分为四组,小切口白内障手法碎核摘除术后,植入非球面人工晶状体(CanonSttarKS-3Ai),设为A组;超声乳化术联合非球面人工晶状体植入,设为B组;超声乳化联合植入球面人工晶状体(CanonSttarKS-X)植入,设为C组;小切口白内障手法碎核摘除术后,植入球面人工晶状体,设为D组。(A组37例,46只眼;B组44例
4、,51只眼;C组39例,48只眼;D组36例,45只眼)。分别测量患者术后1天和1周的视力;待术后3月患者眼球情况趋于稳定时,检查术眼视力(VA)、眼球总像差、对比敏感度、主观视功能及生存质量。采用SPSS17.0统计软件包进行统计分析,利用完全随机设计的方差分析,组间均数的两两比较采用的是LSD法。P<0.05表示有统计学意义。比较两种不同切口方式术后视力、球面像差、对比敏感度、主观视功能及生活质量的差别;相同的手术方式分别联合非球面人工晶状体植入和球面人工晶状体植入后,比较两种不同人工晶状体植入后的视力、球面像差、对比敏感度、主观视功能及生存质量
5、的差别。结果:1、术后1天,A组与B组及C组与D组比较,视力差异均无统计学意义(P>0.05),但A组的均值大于B组,D组的均值大于C组(A组X=4.77,B组X=4.74,C组X=4.4,D组X=4.45)A组和D组比较,视力差异有统计学意义(P<0.05)(A组X=4.77,D组X=4.45,A>D);2、术后1周,A组与B组及C组与D组比较,视力差异均无统计学意义(P>0.05),3但A组的均值大于B组,D组的均值大于C组,具有临床意义;A组和D组比较,视力差异有统计学意义(P<0.05)。3、术后3月,A组与B组比较,VA差异无统计学意义(P
6、>0.05),C组与D组比较,VA亦无显著性差异(P>0.05);4、术后3月,A组与B组比较,总球面像差差异无统计学意义(P>0.05),但A组的总球面像差的均值小于B组,A组与D组比较,总球面像差差异有统计学意义(P<0.05),B组和C组比较,总球面像差差异有统计学意义(P<0.05);5、术后3月,A组与B组比较,在明视、明视眩光1.5cpd、3cpd、6cpd、12cpd、18cpd空间频率及暗视、暗视眩光1.5cpd、3cpd、6cpd、12cpd、18cpd的对比敏感度差异均无统计学意义(P>0.05),A组与D组比较,在明视、明视眩光
7、1.5cpd、3cpd、6cpd、12cpd、18cpd空间频率的对比敏感度,差异有统计学意义(P<0.05),在暗视1.5cpd、3cpd、6cpd、12cpd、18cpd空间频率及暗视眩光1.5cpd、3cpd、6cpd、12cpd、18cpd空间频率的对比敏感度,A组与D组比较,差异有统计学意义(P<0.05),在暗视1.5cpd、3cpd、6cpd、12cpd、18cpd空间频率,暗视眩光1.5cpd、3cpd、6cpd、12cpd、18cpd空间频率,A组与B组比较,差异均无统计学意义((P>0.05);6、术后3月,A组与B组比较,患者的
8、主观视觉功能无统计学差异(P>0.05),A组与D组比较,患者的主观视觉功能亦无统计学差异(P>0.05),
