Four human corneal specimens obtained 5 to 47 months following radial keratotomy were evaluated by correlative microscopy. Repeat radial keratotomies had been performed in two cases. We documented gaping keratotomy incisions, epithelial plugs, and epithelial-lined incisions. In all cases, Bowman's layer was malapposed with slight to moderate fibroblastic activity at the incision sites. Epithelial and endothelial radial ridges were seen in two cases. No endothelial damage was seen under the radial incisions. The morphological evaluation of these specimens show the potential for a poor wound-healing response when corneas with previous corneal surgery and/or pathologic states undergo radial keratotomy.
对4例在放射状角膜切开术后5至47个月获取的人角膜标本进行了相关显微镜评估。其中2例进行了再次放射状角膜切开术。我们记录了角膜切开切口裂开、上皮栓以及上皮覆盖的切口情况。在所有病例中,Bowman层错位,切口部位有轻度至中度的成纤维细胞活动。2例可见上皮和内皮放射状嵴。放射状切口下方未见内皮损伤。这些标本的形态学评估显示,先前接受过角膜手术和/或处于病理状态的角膜进行放射状角膜切开术时,伤口愈合反应可能较差。
