晶状体连续环形撕囊与囊袋阻滞综合征

Continuous curvilinear capsulorhexis and capsular block syndrome

目的 探讨连续环形撕囊 (continuous curvilinearcapsulorhexis,CCC)的大小及某些因素与囊袋阻滞综合征(capsular block syndrom e,CBS)的关系。方法 通过对 6例术中、术后早期、术后晚期囊袋阻滞综合征的观察 ,分析其发生的原因 ,寻找处理方法。结果 (1) CCC直径小于人工晶状体 (IOL )光学直径易发生 CBS;(2 )软性折叠式 IOL襻的前倾角小 ,光学面大的易发生 CBS;(3)分子量大、弹性大的粘弹剂 ,皮质残留易产生 CBS。结论 (1)一般以 CCC的开口恰好遮盖 IOL 光学面的边缘为佳 ;(2 )对于软性折叠式IOL 宜选用襻的前倾角稍大、光学面不宜太大的为佳 ;(3)术中应彻底清除分子量大、弹性大的粘弹剂 ,减少皮质残留。

Objective To analysis the relation of the diameter of continuous curvilinear capsulorhexis and other factors with the capsular block syndrome.Methods We not only analyzed the etiology and clinical characteristic of six cases in intraoperative,early postoperative and lately postoperative,but also discussed the method of treatment.Results (1)When the diameter of CCC was smaller than the one of IOL's optic , the CBS easily happened; (2)When the hoops of the hydroview IOL had a smaller anterior angle and larger optic, the CBS easily happened; (3)When the viscoelestic material and cortex were stayed in capsular or anterior chamber, the CBS easily happened.Conclusion (1)Generaly speaking the size of the CCC should right on the edge of the IOL's optic part; (2)To hydroview IOL, we should choose the one which had a larger anterior angle and a smaller optic; (3)Viscoelastic material which should be cleaned and there was no the rest cortex stayed in the capsular.
