After keratoplasty, you observe that the patient's cornea is cloudy. What should you do?

Choice A rationale Keratoplasty is a corneal transplant procedure. Postoperative cloudiness or opacity of the graft is a primary clinical indicator of corneal rejection. This occurs when the recipient's immune system attacks the donor tissue, leading to inflammation and edema. Prompt reporting to a physician is essential to initiate high-dose corticosteroid therapy to save the graft. Failure to intervene quickly can lead to permanent loss of graft clarity and eventual vision failure. Choice B rationale Emergency surgery is not the immediate standard of care for a cloudy cornea following keratoplasty. The initial management of suspected graft rejection is pharmacological, involving intense topical or systemic immunosuppression to dampen the immune response. While a failed graft might eventually require a repeat transplant, it is not considered an emergency surgical situation in the acute phase of observing cloudiness. The nurse must first ensure a medical evaluation is performed. Choice C rationale Elevating the head of the bed might help reduce generalized ocular edema, but it will not treat the underlying immunological process causing corneal cloudiness during rejection. Furthermore, increasing fluid intake does not have a scientific basis for clearing a cloudy corneal graft. Ocular clarity depends on the health of the endothelial pump layer of the cornea, which is compromised during an immune rejection episode rather than by general hydration status. Choice D rationale Reassuring the patient that cloudiness is normal is a dangerous clinical error. While some mild edema occurs immediately after surgery, persistent or new cloudiness is a hallmark sign of graft failure or rejection. Normal recovery should show progressive clearing of the donor tissue. Telling a patient this is normal could delay life-saving treatment for the graft, leading to permanent blindness in that eye and the need for further complex interventions.
