Four patients developed progressive corneal opacification five to eight months after ultrasonic cataract extraction. Transmission electron microscopy was performed in all patients. Scanning electron microscopy, performed in only one patient, showed radiating folds of Descemet's membrane with pits on its posterior surface as well as focal traumatic disruption probably caused by probe contact. Bullous keratopathy was present in one patient. Two other patients had folds of Descemet's membrane and a thin retrocorneal fibrous layer. All four tumor specimens showed secondary epithelial and stromal changes. The common denominator was the total or partial absence of endothelium or marked alterations of its remnants.
4例患者在超声乳化白内障摘除术后5至8个月出现进行性角膜混浊。对所有患者均进行了透射电子显微镜检查。仅对1例患者进行了扫描电子显微镜检查，结果显示后弹力层有放射状褶皱，其后表面有凹坑，以及可能由探头接触引起的局灶性创伤性破坏。1例患者存在大泡性角膜病变。另外2例患者有后弹力层褶皱和角膜后薄纤维层。所有4个肿瘤标本均显示继发性上皮和基质改变。共同特征是内皮细胞完全或部分缺失或其残余物有明显改变。
