摘要
目的:观察先天性白内障摘除术中行后囊连续环形撕囊(PCCC)防治后发性白内障的疗效及可能出现的并发症。方法:采用小切口先天性白内障单纯囊外摘除或联合人工晶状体植入术,对58例97眼先天性白内障患者进行后囊连续环形撕囊,使晶状体后囊中央形成约3～5mm的囊膜缺损区,行前部玻璃体切除术,以避免后发性白内障的发生。结果:Ⅰ期植入人工晶状体50眼;术后1mo矫正视力≥0.6者18眼,0.5以下42眼;术后3mo矫正视力≥0.6者20眼,0.5以下46眼;术后6～12mo矫正视力≥0.6者21眼,0.5以下50眼。术后1mo第1次复查,无1眼发生后发性白内障,3mo周边部后囊膜浑浊40例,撕囊区清亮。6～12mo16眼发生新生膜,10眼少量玻璃体脱出于前房,玻璃体轻度浑浊,瞳孔不圆18眼,人工晶状体偏位10眼,无1眼发生视网膜脱离。结论:后囊连续环形撕囊是一种经济、安全、高效的防止先天性白内障术后后发性白内障的手术方式,适用于不能配合激光治疗的儿童,但存在一定的复发率。
AIM： To study the surgical operation methods of poste- rior continuous capsulorhexis （PCCC） in congenital cataract.
METHODS： Fifty-eight cases （97 eyes） underwent PCCC with the anterior vitrectomy after the cataract extraction in our hospital from 2004 to 2005.
RESULTS： At lmo after operation, 18 cases had a visual acuity of 0.6 or better and 42 cases had visual acuity of 0.5 or below; At 3mo after operation, 20 cases had a visual acuity of 0.6 or better, 46 cases had visual acuity of 0.5 or below and the central area of the posterior capsule was clear; During 6-12mo after operation,16 cases had fibrous membrane and 8 cases had vitreous prolapse. There was no retinal detachment.
CONCLUSION： PCCC is a safe and effective method toprohibit after-cataract in the congenital cataract extractions, though with certain recurrence.
