Case Report
Abstract
PURPOSE: We report two cases of perforated fungal corneal ulcers, who successfully underwent large therapeutic scleral grafts
as globe salvaging procedures, due to the dearth of donor corneal tissue in the COVID-19 pandemic.
METHODS: Both patients underwent therapeutic grafting for large corneal perforations with trephined donor scleral grafts.
Suturing was done using 9-0 nylon suture. One scleral graft was covered with a conjunctival flap and the other with a total
tarsorrhaphy. Post-operatively, topical antifungal medications were continued.
RESULTS: At the one-month follow-up, both the scleral grafts were found to be healing well. There was no recurrence of
infection. Anatomical integrity was restored in both the eyes.
CONCLUSION: Therapeutic scleral grafting can be done for large corneal perforations, in case of absolute non-availability of
donor corneal tissue. Certain steps like providing access to vascularisation of the graft, need specific attention during the
procedure. These scleral grafts can provide tectonic stability in perforated corneal ulcers.
