Deep or perforating corneal ulcerations or injuries with significant tissue loss may require a corneal grafting procedure. Biologic material (such as Amnion or porcine submucosa “BioSist") is used to fill the defect in the cornea and to help the eye to heal. This graft is sutured directly to the cornea and will remain in place until it will be completely incorporated into the corneal tissue over time. Conjunctival grafting is often required in some ocular conditions (e.g. corneal sequestrum). The conjunctiva is harvested from the same eye and a thin pedicle is directly sutured to the cornea. The cornea in cats has very good healing capacities and very often only a small scar may remain, which does not significantly affect vision.
