Graft rejection occurs when the immune system reacts against a transplanted cornea. This reaction creates swelling, haze, and reduced vision. People may notice redness or sensitivity that worsens over several days. Rejection can happen months or years after surgery. Quick recognition improves the chance of saving the graft.

Symptoms progress as the reaction intensifies. Doctors look for patterns such as rejection lines or new swelling. Early detection supports better outcomes.
They inspect the graft for swelling, rejection lines, and surface changes. Imaging helps assess how deeply the reaction extends. Doctors review the timeline of symptoms to separate rejection from infection or inflammation. Follow-up visits track whether the graft responds to treatment. Early care supports stability.
Watch for a new combo of redness, haze, light sensitivity, and a drop in vision that builds over a few days. Discomfort can feel sharper than usual "dry eye" irritation, and the eye can look more inflamed than normal. Even if the transplant happened years ago, these changes still warrant a same-day call to an eye clinic.
Symptoms often build over several days. Exams show how quickly the reaction grows. Doctors review findings at each visit. Fast care helps protect the graft.
No, many grafts recover with prompt treatment. Response varies by severity. Exams document improvement. Plans adjust as the graft stabilizes.
Yes, late episodes are possible. Doctors advise long-term monitoring. Exams track small shifts. Awareness supports early detection.
New redness, haze, or declining clarity may indicate rejection. Exams confirm the cause. Imaging helps assess severity. Care begins quickly.
