囊袋内白内障摘出后房型人工晶状体植入临床观察

Clinical observation of endocapsular cataract extraction with in-the-bag posterior chamber IOL implantation

目的探讨囊袋内白内障摘出人工晶状体植入术中水平截囊与弧形截囊及撕囊的临床效果。方法按常规白内障囊外摘出术对56眼作水平截囊，94眼作弧形截囊。另对71眼去除前囊，22眼保留前囊进行了对比。结果从术后3月0．5以上矫正视力数及并发症的发生率来看，弧形切口组优于水平切口组（P≤0．05），在后发障的发生率上前囊保留与去除差异有显著性（P＜0．01）。结论（1）囊袋内白内障摘出人工晶状体植入术弧形截囊优于水平截囊。（2）术后去除前囊并抑制晶状体上皮细胞增殖反应是减少手术并发症的一项途径。

Purpose To investigate the clinical results of endocapsular cataract extraction with in-the-bag IOL implantation of arc and horizontal incision capsulotomy and anerior capsulorhexis. Methods The horizontal incision capsulotomy on 56 eye and the are incision capsulotomy on 94 eyes were operated by routine ECCE pricedure, and the anterior capsulorhexis on 71 eyes and retained anterior capsule on 22 eyes were compared. Results The peoperation corrected vistal acuities of 0. 5 or over at three months and reduced the tates of surgical complication of the are incision capsulotomy showed better than the horizontal incision group (P≤0.05). In addition,there was significant difference between the removed anterior capsule group and the retained group(P <0.01). Conclusion. The effects of the arc incision capsulotomy is superior to the horiaontal incision. 2. To remove the anterior capsule in operation and inhibited the proliferative reaction of lentis epithelia is a method of reduces the surgical complications.
