Purpose

To investigate the Descemet membrane endothelial keratoplasty (DMEK) rejection rate following coronavirus disease 2019 (COVID-19) vaccination.

Setting

 Multicenter, retrospective cohort study

Methods

A total of 198 patients who underwent DMEK between January 2006 and December 2020 were divided into two cohorts: consecutive patients who received at least one dose of COVID-19 vaccination in 2021 (vaccination started from February 2021 in Japan) and non-vaccinated patients (control cohort). Patients who had a postoperative observation period of less than 90 days were excluded. The main outcome measurement is the incidence of graft rejection. A Cox proportional hazards regression model was used for comparisons with the non-COVID-19 vaccination group.

Results

Six rejection episodes were observed in 198 patients (124 non-vaccinated and 74 vaccinated patients), with one occurring in the non-vaccinated group and five in the vaccinated group. In the univariate model, only before and after vaccination had a significant effect on rejection episodes (p=0.003). The effect of vaccination was also statistically significant (p=0.004) after adjusting for covariates.

Conclusions

This study suggests a significantly higher rejection rate after COVID-19 vaccination in patients who underwent DMEK. Patients should be warned of the rejection risk and its typical symptoms before receiving the COVID-19 vaccination.
