Eighteen cases (28 eyes) with congenital cataracts are analyzed. Transciliary lensectomy technique was used for cataract extraction (the ages of the infants at the moment of surgery varied from 3.5 to 16 months), aphakia was corrected by highly hydrophilic soft contact lenses worn during the daytime. The limbic vessels, corneal epithelium, endothelium, and thickness were examined. No changes in the epithelium were revealed. Only in one case a trend to a moderate dilatation of a limbic vessel in the upper segment was seen in the presence of microphthalmia. Analysis of endothelial morphometry data has revealed a universal tendency in all the cases: cell square increased and their density reduced (by 45 and 19%, respectively) immediately after surgery. Wearing of contact lenses was associated with a somewhat rise of the cell count, this count persisting below the norm by 10% on an average. Corneal thickness increased by 0.05 mm after surgery and by 0.03 mm during lens correction.
对18例(28只眼)先天性白内障患者进行了分析。采用经睫状体晶状体切除术进行白内障摘除(手术时婴儿年龄在3.5至16个月之间),无晶状体眼通过白天佩戴高亲水性软性角膜接触镜进行矫正。检查了角膜缘血管、角膜上皮、内皮及厚度。未发现上皮有变化。仅1例在小眼球情况下,可见上段角膜缘血管有中度扩张趋势。对内皮形态学测量数据的分析显示,所有病例均有一个普遍趋势:术后即刻细胞面积增加,密度降低(分别降低45%和19%)。佩戴角膜接触镜与细胞计数略有增加有关,该计数平均比正常低10%。术后角膜厚度增加0.05mm,在晶状体矫正期间增加0.03mm。
