What is a common symptom of corneal graft rejection?

Severe eye pain is a common symptom of corneal graft rejection because when the body recognizes the transplanted tissue as foreign, it triggers an immune response. This response can lead to inflammation and damage in the affected eye, resulting in significant discomfort and pain. Patients may experience this pain along with other signs of rejection, such as redness, decreased vision, and sensitivity to light. Monitoring for severe eye pain is crucial following a corneal graft, as early detection of rejection can lead to prompt management and intervention to protect the integrity of the graft.
