Safety and efficacy of corneal tissue harvested from organophosphorous deceased patients.

PURPOSE

To analyze the quality of tissues and outcome of corneal transplants from tissues harvested from the donors of organophosphorus poisoning victims.

METHODS

A retrospective study was carried out on corneas harvested from organophosphorus poisoning victims between January 2016 and December 2018. Details of quality of tissues and outcome following keratoplasty were collected from the eye bank and outpatient records, respectively.

RESULTS

Four hundred and seventy-eight donor corneas were collected from the victims of organophosphorus poisoning during the study period. The mean age of the donor was 38.8 ± 16.5 years. The mean donor-to-preservation time was 6.2 ± 3.2 hours. The mean endothelial cell density on specular microscopy was 2986.5 ± 369.0 cells/mm. Four hundred and twenty-two (88.2%) donor corneas were utilized. Of the 121 corneas utilized at our institute for transplantation, 73 and 48 corneas were for optical and therapeutic/tectonic indications, respectively. Of the 73 optical grafts, 25 patients were lost-to-follow-up and 58.3% (28/48) who came for one-year follow-up were found to be clear.

CONCLUSION

Donor corneas retrieved from organophosphorus poisoning are safe for transplantation. The postoperative outcome of the tissue utilized from these donors is satisfactory.
