目的探讨人工晶体后囊膜夹持术治疗先天性白内障的临床效果。方法对8例(12眼)先天性白内障行白内障摘除联合人工晶体后囊膜夹持术,随访2年以上,观察术眼后囊膜混浊程度、人工晶体位置、人工晶体表面色素沉着、眼内压及虹膜粘连等。结果8例(12眼)患儿均顺利完成白内障摘除加人工晶体后囊膜夹持术,术中无玻璃体溢出,其中1例行人工晶体睫状沟固定加光学部后囊膜夹持。术后随访2年以上,所有术眼维持视轴区透明,无1例患儿需再次行后囊膜截开或YAG激光术,所有术眼保持人工晶体后囊膜夹持、居中位,无1例患者眼内压升高,无色素播散性青光眼发生,2例(2眼)发生虹膜后粘连。结论人工晶体后囊膜夹持术是治疗先天性白内障的有效、安全的方法,能降低术后后囊膜混浊的发生。
Objective To investigate the clinical effect of posterior capsule clamping in the treatment of congenital cataract. Methods Eight cases (12 eyes) of congenital cataract were treated with cataract extraction combined with intraocular lens (CVC) posterior capsule clamping. The patients were followed up for more than two years. The degree of posterior capsular opacification, intraocular lens (IOL) position, intraocular lens Pressure and iris adhesions. Results Eight children (12 eyes) had successful cataract extraction combined with posterior capsular ophthalmoplegia without intraocular lens leakage. Among them, one was treated by artificial ciliary sulcus fixation and posterior capsular ophthalmoplegia. All cases were followed up for more than 2 years. All the eyes maintained clear visual axis. None of the cases underwent posterior capsulotomy or YAG laser. All eyes were retained with posterior capsular clamp, with median, none One patient had elevated intraocular pressure, no disseminated glaucoma, and 2 (2 eyes) had posterior iris adhesions. Conclusion Intraocular lens grafting is an effective and safe method for the treatment of congenital cataract. It can reduce the incidence of posterior capsular opacification.
