The aim of this study was to analyze the impact of COVID-19 lockdown on keratoplasty and Eye Banking in India.
An e-mail survey was conducted among cornea surgeons and eye bankers of India. Participants were asked to report their practice patterns for the management of corneal perforation during lockdown, different preservative media used during and before lockdown, and waiting time and waiting time before COVID-19 lockdown.
Eight of 20 eye banks did not collect corneal tissue during April-June 2020; in contrast, 9 eye banks used to collect around 100 corneas per month during pre-COVID-19 time. Two-third of the surgeons (66.1%, n = 41/62) did not perform any corneal tissue transplant between April and June 2020. Cyanoacrylate tissue adhesive application was the most commonly, performed procedure (79%, n = 49/62) for tectonic purpose during this period. Glycerol was the most preferred alternative preservation method considered by both the groups. More than half of the surgeons (64.5%, n = 40/62) had an average waiting time of <1 week for scheduling patients for keratoplasty in pre-COVID-19 period.
There is was a significant drop in both corneal tissue retrieval and utilization during during COVID-19 lockdown. There was a felt need for an alternate long term storage media.
本研究旨在分析 COVID-19 封锁对印度角膜移植和眼库的影响。
对印度角膜外科医生和眼库工作人员进行了电子邮件调查。参与者被要求报告他们在封锁期间管理角膜穿孔的实践模式、封锁期间和之前使用的不同保存介质，以及等待时间和 COVID-19 封锁前的等待时间。
在 20 家眼库中，有 8 家在 2020 年 4 月至 6 月期间没有采集角膜组织；相比之下，在 COVID-19 之前，有 9 家眼库每月通常采集 100 多片角膜。三分之二的外科医生（66.1%，n=41/62）在 2020 年 4 月至 6 月期间没有进行任何角膜组织移植。氰基丙烯酸酯组织粘合剂的应用是这期间最常进行的（79%，n=49/62）用于组织修复的程序。甘油是两组都认为最可取的替代保存方法。超过一半的外科医生（64.5%，n=40/62）在 COVID-19 之前，安排角膜移植患者的平均等待时间<1 周。
在 COVID-19 封锁期间，角膜组织的获取和使用都显著下降。人们感到需要一种替代的长期储存介质。
