概括

一种新的无角膜整形技术可以选择性地去除和替换患病的角膜层. 这种封闭的方法在不影响内皮细胞的情况下显著改善了视力,为肌肉缩症提供了一个有前途的替代方案.

科学领域:

  • 眼科医生 眼科 眼科
  • 再生医学是一种再生医学.
  • 手术创新 在外科创新.

背景情况:

  • 目前使用的像DALK和PKP这样的角质整形方法都有局限性.
  • 这些包括表面层的参与,合需求和纹.
  • 需要新的方法来治疗肌肉变和退化.

研究的目的:

  • 介绍和评估一种新的闭合无角质整形技术.
  • 具体来说,角膜内选择性树叶移植用于孤立的树叶病理.

主要方法:

  • 角膜内选择性树皮移植在患有树皮退行症的患者身上进行.
  • 这项手术涉及取代患病的肌层,同时保留曼层和德塞梅特的膜.
  • 一个伴随的老年白内障也得到了解决.

主要成果:

  • 该技术通过封闭的方法成功地替换了病理改变的肌层.
  • 最好纠正的视力敏度从0.01提高到0.6.
  • 在24个月的随访期间,内皮细胞密度保持稳定.

结论:

  • 角膜内选择性侧膜移植对于有完整角膜层的侧膜变/退化是可行的.
