Background: The aim of this study is to assess the incidence and characteristic of corneal grafts and its association with diabetes mellitus in Poland in the years 2013–2017. Methods: The retrospective survey of the National Database of Hospitalizations was performed to identify all the corneal transplantations in Poland between January 2013 and December 2017. The comorbid diseases, in particular diabetes mellitus, were verified in the patients’ medical history. The logistic regression was applied to demonstrate the factors related to urgent surgeries. Results: In total, 5069 corneal grafts in 4710 patients were reported in the years 2013–2017. The number of CTs gradually increased by 37% from 914 (2.37 surgeries per one hundred thousand population) in the year 2013 to 1250 (3.25 surgeries per one hundred thousand population) in 2017, the final year of the study. CT incidence was the highest in subjects aged 70 years or older: 13.18 per one hundred thousand population in the year 2017. On average, about 22.43% of procedures were performed in patients with DM. The chance of urgent surgery was mostly correlated with full thickness CT and patients’ age. Conclusions: Despite the relatively low value of CT in Poland, there was an increasing number of CTs in the analyzed period.

2013-2017 年波兰糖尿病与角膜移植术之间的关联

背景：本研究的目的是评估 2013-2017 年波兰角膜移植物的发生率和特征及其与糖尿病的关系。方法：对国家住院数据库进行回顾性调查，以确定2013年1月至2017年12月期间波兰所有角膜移植手术。在患者的病史中证实合并症，特别是糖尿病。应用逻辑回归来证明与紧急手术相关的因素。结果：2013-2017 年共报告了 4710 名患者的 5069 例角膜移植物。CT 数量从 2013 年的 914 台（每十万人 2.37 台手术）逐渐增加到 2017 年的 1250 台（每十万人 3.25 台手术），增长了 37%，研究的最后一年。CT 发病率在 70 岁或 70 岁以上的受试者中最高：2017 年每 10 万人中有 13.18 人。平均约 22.43% 的手术是在 DM 患者中进行的。紧急手术的机会主要与全层CT和患者年龄相关。结论：尽管波兰的 CT 值相对较低，但在分析期间 CT 的数量却在增加。
