Several decades ago, penetrating keratoplasty was a challenge to corneal surgeons. Constant effort by the corneal surgeon to improve the outcomes as well as utilization of the available resources has led to a revolutionary change in the field of keratoplasty. All these efforts have led to the evolution of techniques that allow a corneal surgeon to disease-specific transplant of individual layers of corneal "so-called component corneal surgery" depending on the layer of cornea affected. This has led to an improvement in corneal graft survival as well as a better utilization of corneal tissues. This article reviews the currently available literature on component corneal surgeries and provides an update on the available techniques.
几十年前，穿透性角膜移植术对角膜外科医生来说是一项挑战。角膜外科医生不断努力改善手术效果并合理利用现有资源，这在角膜移植领域带来了革命性的变化。所有这些努力促使了相关技术的发展，使角膜外科医生能够根据受影响的角膜层进行针对特定疾病的角膜各层单独移植，即“所谓的成分角膜手术”。这提高了角膜移植的存活率，也更好地利用了角膜组织。本文回顾了目前关于成分角膜手术的现有文献，并提供了现有技术的最新情况。
