Use of cornel patch graft to repair scleral pr corneoscleral defects

RESUMO

Different types of graft materials, such as bucal mucosal membrane, auricular cartilage, conjunctiva, fascia lata, periosteum and dermal autografts, aortic and scleral homografts and synthetic materials have been used in order to repair or reinforce scleral or corneoscleral defects with variable results. We report patients with a minimum one year follow-up, successfully treated with corneal patch graft. In all cases, the corneal patch graft healed well without any evidence of further melting, infection or rejection. The grafts remained intact and able to support the defect, with a favorable final cosmetic appearance. Therefore, we emphasize the importance of human donor cornel tissue as an excellent alternative graft material to reinforce or repair scleral or corneoscleral defect.
