We describe a free-floating cyst in the anterior chamber after cataract surgery in a 73-year-old woman who underwent uneventful phacoemulsification in her right eye (OD). The best-corrected visual acuity one week after surgery was 20/20 OD; however, six weeks later, she noted the onset of intermittent "shadows" in this eye whenever she changed head position. Slit lamp examination showed a round, free-floating, clear cyst (3-4 mm in diameter) that traversed the central visual axis during eye movement. The cyst was removed through a limbal incision, by expressing it gently out of the eye with viscoelastic injection into the anterior chamber. On pathological examination the inner wall of the cyst was lined with non-keratinized squamous epithelium, typical of ocular surface cells.
我们描述了一名73岁女性白内障手术后前房内的一个游离囊肿。该女性右眼行超声乳化白内障吸除术，手术过程顺利。术后一周最佳矫正视力为右眼20/20；然而，六周后，她注意到每当改变头部位置时，这只眼睛就会出现间歇性“阴影”。裂隙灯检查显示一个圆形、游离、透明的囊肿（直径3 - 4毫米），在眼球运动时穿过中央视轴。通过角膜缘切口，向前房内注入粘弹剂，将囊肿轻轻挤出眼外，从而将其取出。病理检查显示囊肿内壁衬有非角化鳞状上皮，这是眼表细胞的典型特征。
