AcrySof与PMMA人工晶体临床对比观察

Clinical comparison of AcrySof and PMMA intraocular lens

研究人工晶体材料与术后视力、前房炎症反应以及后囊混浊的关系。方法 :1 78例 ( 1 90眼 )老年性白内障由同一位医生进行超声乳化手术 ,其中 90眼植入 Acry Sof人工晶体 ,1 0 0眼植入 PMMA人工晶体 ,观察术后视力、前房炎症和后囊混浊的发生情况。结果 :术后 1天视力≥ 0 .5者 ,Acry Sof组占 83.33% ,PMMA组占 5 6 % ;≥ 1 .0者 ,分别为 2 6 .7%、 6 %。术后 3个月视力≥ 0 .5者 ,Acry Sof组 88.89% ,PMMA组 84% ;≥ 1 .0者 ,分别为 82 .2 2 %、 5 8%。术后前房炎症及后囊混浊的发生率 ,Acry Sof组显著低于 PMMA组。结论 :Acry Sof人工晶体植入术后视力恢复好 ,前房炎症及后囊混浊发生率显著低于

To study the relationship between IOL biomaterials and visual acuity,anterior chamber inflammation and posterior capsule opacification(PCO).Methods:On 190 eyes of 178 patients with senile cataract phacoemulsification(phaco)was performed by a single surgen.90 eyes receive AcrySof IOl and 100 eyes receive PMMA IOL.The postoperative vision,anterior chamber inflammation and PCO were observed.Results:Postoperatively,at one day the visual acuities were 0 5 or better,AcrySof group in 83 33% and PMMA group in 56%,and 1 0 or better in 26 7% and 6% respectively;and at three months the visual acuities were 0 5 or better,AcrySof group in 88 89%,and PMMA group in 84%,and 1 0 or better in 82 22% and 58% respectively.There was a significant difference in percentage of anterior chamber inflammation and PCO between the AcrySof and PMMA IOl.Conclusion:AcrySof IOL implantation can make better visual acuity rehabiliation than PMMA.AcrySof IOL were associated with less percentage of anterior cnamber inflammation and PCO.
