研究人员创建了第一个 3D 打印的角膜来消除失明

2018-05-31 佚名 cnBeta

纽卡斯尔大学的研究人员已经宣布,他们已经设法 3D 打印角膜,即人眼最外面的部分。目前,全球有 1000 万人需要手术来预防沙眼等疾病引起的角膜失明。最重要的是,由于事故或疾病导致的角膜疤痕让近 500 万人完全失明,现在,这种生产角膜的高科技方法可以结束这一切。



纽卡斯尔大学的研究人员已经宣布,他们已经设法 3D 打印角膜,即人眼最外面的部分。目前,全球有 1000 万人需要手术来预防沙眼等疾病引起的角膜失明。最重要的是,由于事故或疾病导致的角膜疤痕让近 500 万人完全失明,现在,这种生产角膜的高科技方法可以结束这一切。

它通过从健康捐献者的角膜获取干细胞并将其与凝胶混合在一起,创造了研究人员认为的“生物墨水”,这种独特凝胶,海藻酸盐和胶原蛋白的组合,保持干细胞的活力,生产足够坚硬的材料以保持其形状,但足够柔软以从 3D 打印机的喷嘴挤出。

为了为特定人员定制角膜,科学家能够在创建符合个体大小和形状的角膜之前扫描患者的眼睛。但是,目前这种技术还没有准备好用于大规模使用,这种 3D 打印角膜现在将不得不进行进一步的测试,可能要用几年时间才能将它们用于移植。
