摘要
目的评估后囊连续环形撕囊术预防人工晶状体（IOL）植入术后囊袋收缩的作用。方法年龄相关性白内障25例（50眼），分别左眼行超声乳化吸出IOL植入术联合后囊环形撕囊术（后囊撕囊组），右眼行超声乳化吸出IOL植入术未联合后囊撕囊术（对照组）。随访观察术后前房深度及视力。结果两组术后1周至3个月前房深度逐渐加深，后囊撕囊组，术后3个月与1个月时相比，前房深度增加（0．01±0．10）mm，差异无统计学意义（t=0．86，P=0．78）；对照组，术后3个月与1个月时相比，前房深度增加（0．13±0．19）mm，差异有统计学意义（t=3．08，P=0．02）。术后两组最佳矫正视力比较差异无统计学意义（t=1．09，P=0．26）。结论超声乳化吸出人工晶状体植入术未联合后囊撕囊术术后前房深度有逐步加深的趋势，联合后囊撕囊术可减轻因囊袋收缩所致的前房深度加深。
Objective To evaluate the effect of posterior eontinuous eurvilinear eapsulorrhexis （PCCC） for preventing capsule contraction after phaeoemulsifieation and intraoeular lens implantation. Methods Fifty eyes of 25 patients were enrolled in this study. The left eyes received cataract surgery with PCCC （the PCCC group）, and all the right eyes received ordinary phacoemulsifieation surgery without PCCC （the eontrol group）. Foldable aspherical IOLs of the same type were implanted in both groups. All patients were followed up for 3 months after the surgery. The best-corrected visual acuity （BCVA） and the depth of the anterior chamber （ACD） were observed. Results The ACD increased gradually in both two groups during the follow-up of 3 months. The ACD was increased by （0.01 ±0.1 ） mm in the PCCC group 3 months after the surgery , and the differenee was not statistically significant （ t = 0. 86, P = 0. 78 ） compared with the ACD 1 month after the surgery. But in the eontrol group the ACD was increased by （0. 13±0. 19） mm three months after surgery, and the differenee was statistically significant （ t = 3.08, P = 0.02 ） compared with that 1 month after surgery. The difference in postoperative BCVA between the two groups was not statistically significant （ t = 1.09, P = 0. 26）. Conclusion The ACD increased gradually after cataract surgery in beth of the two groups. PCCC is useful to minimize postoperative ACD increase eansed by capsule contraction.
