摘　　要：目的　探讨粘弹性物质维持前房对环形撕囊的作用。方法　回顾总结 12 4例白内障囊外摘除术中 ,分别用林格氏液灌注维持前房及使用粘弹性物质透明质酸钠或甲基纤维素维持前房 ,连续环形撕囊的成功率。结果　使用林格氏液病例 ,连续环形撕囊成功率最低 ,仅 2 5.7% ,使用甲基纤维素病例成功率较高 ,4 0 .7% ;使用透明质酸钠病例成功率最高 ,达 77.4 % ,统计学处理P <0 .0 0 5,三者有显著性差异 ;使用Healon的成功率高于使用国产透明质酸钠病例 ,但统计学处理 ,P >0 .0 5,差异无显著性。结论　透明质酸钠效果最好 ,它具有高分子量 ,因而粘滞性强 ,维持前房能力强。Objective To study the effect of viscoelastic materials keeping anterior chamber on circular capsulorxis. Methods The success rate of continuous circular capsulorhexis was retrospectively summed up in 124 patients of extracapsular cataract extraction who were respectively adopted ringer's solution and viscoelastic materials sodium hyaluronate or methylcellulose keeping anterior chamber. Results The success rate of continuous circlular capsulorhexis in cases using ringer's solution was lowest, only 25.7%.The success rate of continuous circular capsulorhexis in cases using methylcellulose was higher, 40.7%.The success rate of continuous circulor capsulorhexis in cases using sodium hyaluronate was highest, 77.4%.There was obvious difference in three groups, ( P<0.005). The success rate of Healon was superior to sodium hyaluronate of China but there was no obvious difference statistically(P>0.05). Conclusion It is necessary to use viscoelastic materials in circular capsulorhexis operation. The effect of sodium hyaluronate is best. The product quality of China is close to the imported.
