摘　　要：目的探讨在先天性白内障手术中前部玻璃体切除对术后视轴区后囊浑浊的预防作用。方法对61例(122眼)2～8岁的儿童双眼先天性白内障施行晶状体超声乳化联合人工晶状体植入。右眼为对照组(61眼)联合后囊连续环形撕囊;左眼为研究组(61眼)联合后囊连续环形撕囊及前部玻璃体切除。随访6～66月,平均31.6月观察记录两组视轴区浑浊情况和其它并发症。结果视轴区浑浊发生率,对照组为36.07%,研究组为8.20%,研究组明显低于对照组(P<0.01)。在能够进行视力检查的48例(96眼)中,术后最佳矫正视力≥0.3者,对照组为30只眼(62.50%);研究组为39只眼(81.25%),研究组高于对照组,差异有统计学意义(P<0.05)。结论对于(2～8岁)儿童先天性白内障,在施行晶状体超声乳化联合人工晶状体植入的同时,联合后囊连续环形撕囊及前部玻璃体切除,可安全有效的减低术后视轴区浑浊的发生率。Objective To investigate the role of anterior vitrectomy for preventing aftercataract in visual axiatea congenital cataract surgery. Methods The study comprised 122 eyes of 61 children aged 2 - 8 years old with congenital cataracts. Primary posterior continuous curvilinear capsulorhexis （PCCC） and posteri- or chamber intraocular lens （IOLs） implantaiton were performed in all eyes. vitrectomy was not performed in 61 eyes （Group A）, and anterior vitrectomy was performed other 61 eyes （Group B）. The visual axis opacification and various complications were observed for 6 - 66 months, average 31.6 months. Results 36.07% eyes in Group A and 8.20% eyes in Group B developed visual axis opacification and the fifference was statistically significant （p 〈 0.01 ）. Among 96 eyes of 48 children who could do visual examination, The best corrected visual acuity was ≥ 0.3 in 30 eyes （62.50%） in group A and 39 eyes （81.25%） in group B. The difference was statistically significan （p 〈 0.05 ）. Conclusion Tt suggest that anterior vitrectomy can effectively prevent visual axis opacification along with primary PCCC in children with congenital cataract who are between 2 and 8 years old.
