Recovery and access to end-of-life corneal tissue for corneal transplantation, training and research is globally maldistributed. The reasons for the maldistribution are complex and multifaceted, and not well defined or understood. Currently there are few solutions available to effectively address these issues. This review provides an overview of the system, key issues impacting recovery and allocation and emphasises how end-user ophthalmologists and researchers, with support from administrators and the wider sector, can assist in increasing access long-term through sustaining eye banks nationally and globally. We posit that prevention measures and improved surgical techniques, together with the development of novel therapies will play a significant role in reducing demand and enhance the equitable allocation of corneas.

角膜供应和使用技术减少其需求：回顾

用于角膜移植、培训和研究的报废角膜组织的恢复和获取在全球分布不均。分布不均的原因是复杂和多方面的，而且没有很好的定义或理解。目前，有效解决这些问题的解决方案很少。本综述概述了该系统、影响恢复和分配的关键问题，并强调最终用户眼科医生和研究人员如何在管理人员和更广泛部门的支持下，通过在全国和全球范围内维持眼库来帮助增加长期访问。我们认为，预防措施和改进的手术技术以及新疗法的开发将在减少需求和促进角膜的公平分配方面发挥重要作用。
