The precautions to be taken after cornea transplantation mainly include paying attention to eye hygiene, preventing infection, eating a light diet, eating more fresh fruits and vegetables, and ensuring sufficient sleep. 1. Pay attention to eye hygiene and prevention of infection: After cornea transplantation, special attention should be paid to eye hygiene, because bacteria and other pathogenic microorganisms are very likely to invade the body through the wound, and should be adequately protected so as not to cause eye infection. 2. Eat a light diet and plenty of fresh fruits and vegetables: After the operation, we should ensure balanced nutrition, especially pay attention to the intake of vitamins, proteins and other nutrients to help strengthen the body’s immunity and promote the recovery of the wounds. 3. Ensure adequate sleep: Adequate sleep is one of the necessary factors to ensure good health, so adequate rest after surgery is essential for the recovery of health. After corneal transplantation, you should follow the doctor’s instructions for reasonable recovery to maximize the efficacy of the surgery.
