ABSTRACT

Introduction: the COVID-19 pandemic, originating from SARS-CoV-2, has generated a decrease in donation programs. The possibility of transmission is high, therefore fresh corneal tissue is not available. The objective was to document the therapeutic results with the use of corneal tissue preserved in glycerin in patients undergoing emergency corneal transplantation. Material and methods: retrospective, descriptive study. The clinical evolution of the cases treated for corneal transplantation was documented. The records of patients who have undergone emergency corneal transplantation using corneal tissue in glycerin were included. The statistical program SPSS and Excel were used. Results: a total of 19 patients; 13 (68.4%) were male and 6 (13.5%) female. The main indication was infectious corneal ulcer in 7 (36.8%) and perforated in 6 (31.5%) patients. 17 cases (89.4%) achieved the preservation of ocular integrity. Complications included glaucoma 1 (5.3%) and corneal tissue lysis 3 (15.7%). Conclusions: corneal tissue preserved in glycerin is a good option for emergency corneal transplants, as it maintains ocular integrity and saves the eyeball when fresh corneal tissue is not available.
