摘要

Objective

of this study is to describe the clinical application and outcomes of scleral patch grafts in managing corneal perforations, particularly in settings with limited access to donor corneal tissue.

Methods

A case series of three patients with corneal perforation managed using scleral patch grafts was presented, accompanied by a literature review. The indication for scleral grafting included infective keratitis in two cases and sterile corneal melt in one case. All cases were treated in a resource-limited setting where donor corneas were unavailable at the time of presentation.

Results

All three cases achieved successful anatomical restoration following scleral patch grafting. Case 3 required a secondary procedure due to graft failure. Cases 1 and 2 subsequently underwent optical penetrating keratoplasty, which resulted in favourable visual outcomes. The scleral patch graft served as a temporary but effective measure to preserve globe integrity and prevent further complications until definitive treatment could be performed in resource-constrained settings.

Conclusions

Scleral patch grafting is a viable temporizing option for the management of corneal perforations when donor corneal tissue is unavailable. It provides structural support, preserves ocular integrity, and facilitates subsequent optical keratoplasty, making it a valuable intervention in resource-constrained settings.
