详细

背景:角膜胶原交联(CCC)是预防和治疗进展性角膜扩张最有效的方法之一。在文献中偶尔有关于运用CCC长期结果的数据,但仅限于最常见的角膜扩张形式之一—圆锥角膜。在发表的刊物中,运用CCC对角膜扩张其他比较常见形式的有效性没有长期结果。再就是屈光手术后的继发性扩张。透明边缘性角膜变性的诊断病例也有所增加。在文献中,我们没有找到运用该方法治疗各种形式的角膜扩张的有效性的长期结果进行比较分析。

研究目的在运用CCC治疗各种形式的角膜扩张并分析长期结果的基础上,评估其有效性。

材料与方法:对不同形式的角膜扩张患者运用CCC术后6年的结果进行了分析。该研究的疾病分类学的结构包括圆锥角膜、透明边缘性角膜变性和继发性扩张。圆锥角膜患者有30例(30只眼睛),透明边缘性角膜变性患者有30例(30只眼睛),继发性扩张患者有30例 (30只眼睛)。在观察的第一和第二年由一位专家对患者进行了角膜胶原交联。随后,对角膜状态和视觉功能的变化进行了6年的监测。通过术前及术后的检查结果来评估其有效性。

结果:所有组的最大矫正视力均有所提高,角膜表面不对称指数及其屈光力在扩张中部均有所下降。但在圆锥角膜和继发性扩张患者的组中使用CCC的效果最明显。
