We present one case of capsular bag distension associated with lens phacoemulsification, capsulorhexis and posterior chamber intraocular lens (IOL) insertion. Capsular bag distension is a rare postoperative complication of continuous tear anterior capsulotomy and presents the following characteristics: (1) postoperative myopic over-refraction; (2) shallowing of the anterior chamber associated with anterior shift of the IOL and the iris diaphragm; (3) important posterior distension of the posterior capsule and (4) sealing of the capsule to the anterior surface of the IOL. In our case, recovery of vision was incomplete after cataract surgery although the procedure was uneventful and no other ocular pathology was found. A neodymium: YAG laser anterior capsulotomy peripheral to the edge of the IOL remedied the situation allowing the capsular fluid to regress into the anterior chamber and the IOL to return in a normal posterior position.
我们报告一例与晶状体超声乳化、撕囊及后房型人工晶状体（IOL）植入相关的囊袋扩张病例。囊袋扩张是连续环形撕囊术后一种罕见的并发症，具有以下特征：（1）术后近视过矫；（2）前房变浅伴IOL和虹膜隔向前移位；（3）后囊重要的向后扩张；（4）囊膜与IOL前表面贴合。在我们的病例中，尽管手术过程顺利且未发现其他眼部病变，但白内障手术后视力恢复不完全。在IOL边缘外周进行钕：钇铝石榴石激光前囊切开术纠正了这种情况，使囊袋内液体回流至前房，IOL恢复到正常的后位。
