The situation of corneal transplants in Brazil resembles that of other countries, where it is observed an insufficient offer of cornea to meet the need of carrying out transplantations. This study aims to characterize cornea donors and patients who underwent transplantation, evaluating epidemiological data, indications from surgery, presence of rejection and length of waiting list. Method: This is an observational, transversal and descriptive study, where data were collected from all donors and receptors charts, filed at the Notification, Catchment and Distribution Center of Sergipe, from January 2000 to April 2009, and these data were summarized as average and standard deviation or medians and percentiles for the quantitative variables, while for categorical variables it were used simple frequency, percentages and trust interval for 95% when necessary. Results: It was observed a total of 272 donors (544 corneas), from which 415 corneas were recovered for transplantation, and that was the total amount of receptors surveyed. The average donors age was 39.4 ± 15.9 years, with male predominance (68%) and the most frequent cause of death was trauma (56%). There was a recovery of 76.2% from the donated corneas, 7.7% among the total donations tested positive for infectious diseases, which prompted its discard. Optsol® was the solution most used for preservation (56%). Among cornea receptors there was a predominance of transplant indication for bullous keratopathy (37.3%), followed by scarring (23%) and keratoconus (18.3%). The average receptors age was 51.4 ± 25.0 years, 51% males and 49% females. The percentage of rejection was 8.7%. The median waiting time for transplantation was 9.9, months, the 25 percentile was 2.2 months and the 75 percentile was 38.6 months. Conclusion: Cornea donors were predominantly young males, victims of trauma, mostly resulting in good quality of the cornea with a high recovery of these donations. The rejection level was considered low. Waiting time for transplantation was considered high, and there has been a large increase in the waiting list, that has tripled over almost 10 years. The main indication for transplant surgery was pseudophakic bullous keratopathy.
