ABSTRACT

Introduction: on March 11, 2020, the World Health Organization officially declared the COVID-19 pandemic situation, which created a challenge for health systems. In the area of donation and transplantation, the already common imbalance intensified, with a greater decrease in donors, generating a decrease in global activity. However, within the activity of the establishments with Corneal Tissue Bank activity, they have the function of preserving and safeguarding fresh and long-term corneal tissue. Objective: a reduction in corneal tissue donation activity of 66.21% was documented in 2020, compared to 2019 prior to the pandemic. Material and methods: observational, cross-sectional, retrolectivo study. Two years (2019 and 2020) were evaluated. All the activity of procurement and processing of corneal tissue for transplant purposes registered in a Tissue Bank in Mexico was documented. A descriptive evaluation was carried out, with data representation in tables and graphs and an inferential evaluation for the comparison of the periods. Results: a reduction of 58.34% was documented in 2020, compared to 2019 prior to the pandemic. Conclusions: the COVID-19 pandemic in Mexico had a significant impact on the corneal tissue donated in the acute period of the health contingency; however, despite the decrease, the corneal tissue stored in the establishment along with the little activity that was carried out with fresh tissue, the long-term preservation of corneal tissue allowed continuity of the medical care of the Corneal Transplant program with 100% attention to all ophthalmological emergencies that required a transplant in the period of health contingency that generated a decrease in donors.
