摘要
目的 :探讨单片式Acrysof人工晶状体折叠镊植入与推注器植入后视力恢复、散光度及角膜内皮细胞密度变化。方法 :对术后 3个月内能按时完成随访并除去因合并其他眼病影响术后视力者 ,折叠镊植入与推注器植入各 5 0只眼的资料进行回顾性研究 ,将术后各期视力、散光度及角膜内皮细胞密度变化进行对比研究。结果 :术后第 1天两组平均视力都大于0 5 ,两组之间差异有非常显著意义 (u检验 ,P <0 0 1) ,术后 7天两组间无差异 (u检验 ,P >0 0 5 )。术后 7天两组散光度差异有显著意义 (t=2 2 0 5 ,P <0 0 5 ) ,术后 1、3个月时两组间散光度差异均无显著意义 (t=0 4 71,t=0 136 ,P >0 0 5 )。术后角膜内皮细胞密度两组间差异无显著意义 (t=0 4 34,P >0 0 5 )。结论 :两种方法均能获得良好视力恢复 ,推注器植入组视力恢复更快 ,角膜散光度变化更小。在植入单片Acrysof人工晶状体术中 ,值得推荐用推注器。
Objective:To investigate the changes of visual acuity,astigmatism and corneal endothelial cells′ density after implantation of Acrysof intraocular lens with phacofolder forceps or injector.Method:Phacofolder forceps and injector were used in 50 eyes respectively.The changes of visual acuity,astigmatism and corneal endothelial cells′ density were selected for retrospective analysis.Results:At the first postoperative day,there was significant statistic difference (u test P<0.01) between the visual acuiies in two groups,but at the seventh day,the difference has no statistic significance (u test P>0.05).At the seventh postoperative day,there was significant difference in astigmatism between two groups,but there were no much difference between the two groups at the first and the third postoperative month (t=0.471,t=0.136 respectively P>0.05).There was no statistic significant difference of the corneal endothelial cells density between these two groups.Conclusion:Visual acuities recovered well in both two groups but faster in the injector group,and the astigmatism is less.Injector is advisable to be used in the implantation of Acrysof intraocular lens.
