本技术涉及医疗器械
,具体地说,是一种一体化角膜染色针。
技术介绍
角膜白斑病常发生在角膜炎和角膜伤口上,有多种因素,如物理、化学和先天性。角膜混浊往往会导致美容问题。如果角膜白斑区域位于视觉轴区,则会造成视觉损失,甚至是功能性失明。治疗这种疾病的方法包括功能性方法和美容方法。功能性方法包括角膜移植,如穿透性角膜成形术(PK)和层状角膜成形术(LK),是角膜斑翳或那些想恢复视力的患者的一种极好的治疗方法。然而,在角膜移植后,许多人会遇到移植物排斥反应和慢性内源性细胞丧失等种种问题。当视觉重建无效或者没有这种选择项时,可以使用已被使用了几个世纪的Keratopigmentation(KTP)或使用硫酸铜来给角膜染色,后来,更多的化学成分,如Indiaink,已经被外科医生用来给角膜白斑病患者的白斑部位染色。角膜染色术用于无视力且恢复无望的角膜白斑患者的美容已有多年的历史。角膜美容染色手术方式有角膜清创术后前基质内染色、经角膜上皮穿刺基质内染色以及板层角膜移植联合层间染色法等。但这些手术方式都因为各自的局限和缺点在临床应用越来越少。最近角膜 ...
