摘　　要：【摘要】目的探讨在先天性白内障手术中预防术后后囊浑浊的方法。方法44例（46眼）先天性白内障手术，前后囊双撕囊联合人工晶状体光学区后囊口嵌顿术作为观察组；同期进行的36例（38眼）先天性白内障手术前后囊双撕囊植入人工晶状体作为对照组。两组术后随访视力及晶状体后囊中央部浑浊程度进行统计学分析。结果术后矫正视力两组比较，观察组视力优于对照组（x2=5．006,X2=6．717，P〈0．05）。在两组后囊中央部浑浊同级别比较中，观察组：对照组，0级者35：9，1级者5：12；2级者3：8；3级和4级者3：9。观察组无浑浊例数较对照组明显增多，各级别后囊浑浊例数观察组均低于对照组（X2=22．91，P〈0．05）。结论先天性白内障手术中，行前后囊双环形撕囊联合人工晶状体光学区后囊口嵌顿术，能减少视轴区后囊浑浊的发生，有助于视功能的恢复。Objective To explore the surgical preventive methods of posterior capsule opacity in congenital cataract. Methods 80 cases （ 84 eyes） of congenital cataract were enrolled in the study who un- derwent cataract extraction and intraocular lens implantation. All cases were divided into two groups： the ex- perimental group（46 eyes of 44 cases） and the control group （38 eyes of 36 cases） . The experimental group underwent anterior capsulorhexis, posterior capsulorhexis and the intraocular lens optical unit was em- bedded in the margin of the posterior capsular opening. Only anterior capsulorhexis and posterior capsulo- rhexis were performed in the control group. The visual acuities and degrees of posterior capsule opacity were compared between two groups. Results The patients＇ corrected visual acuities in the experimental group were better than that in the control group after surgery. The differences were statistically significant （X2 = 5. 006 ,P 〈0.05 ）. The results of degrees of posterior capsule opacity were 35 cases in experimental group and 9 cases in control group at level 0,5 cases in experimental group and 12 cases in control group at level 1, 3 cases in experimental group and 8 cases in control group at level 2, 3 cases in experimental group and 9 cases in control group at level 3 and level 4. The ratio of clear posterior capsule in experimental group was higher than that in control group significantly. The incidences of posterior capsule opacity in experimental group were lower than that in control group at five different levels ,the differences were statistically significant （X2 = 22. 91 ,P 〈 0.05 ）. Conclusion Anterior capsulorhexis, posterior capsulorhexis and intraocular lens optical unit embedded in the margin of the posterior capsular opening can reduce the incidence of posterior capsule opacity in congenital cataract surgery and benefit visual function recovery.
