目的 探讨人工晶状体前膜形成与晶状体支撑襻固定位置之间的关系。方法 对45例45只眼老年性白内障行白内障摘出及人工晶体植入术后人工晶状体前膜形成进行回顾性分析术中人工晶状体襻固定的位置。结果 人工晶状体襻固定于囊袋内1只眼;不对称囊袋和睫状体沟内固定26只眼;18只眼为完全睫状体沟内固定。结论 人工晶状体襻不完全睫状体沟内固定是前膜形成的因素之一,而囊袋内固定人工晶状体则可减少人工晶状体前膜的形成。
Objective To investigate the relationship between the formation of anterior lens and posterior lens capsule. Methods 45 eyes of 45 eyes with senile cataracts were retrospectively analyzed for the posterior chamber intraocular lens (IOL) fixation after cataract extraction and intraocular lens implantation. Results Intraocular lens (IOL) was fixed in one of the capsular bag, 26 eyes were fixed in asymmetric capsular bag and ciliary body, and 18 eyes were completely fixed in the ciliary body. Conclusion Intraocular lens (IOL) fixation in the ciliary body is one of the factors in the formation of anterior membrane. Intraocular lens implantation in the capsular bag can reduce the formation of anterior lens capsule.
