The main contraindications for patients one year after retinal detachment surgery include avoiding strenuous exercise, not exposing the eye to trauma, and avoiding squeezing the eye. Retinal detachment is a common disease in ophthalmology and belongs to a type of fundopathy, which can threaten patients’ visual function and cause symptoms such as vision loss and visual field defects. Once a retinal detachment occurs, the patient needs to have surgery to reset the retina as soon as possible. One year after surgery, the retina has been reset, but patients should still avoid strenuous exercise. Patients should also avoid trauma to the eye and avoid squeezing the eye, as there is a risk of retinal detachment occurring again. Patients should also visit the ophthalmology department at the hospital for regular checkups to see how healthy the retina is, such as a funduscopic examination. Post-operative retinal detachment patients are advised to follow the doctor’s instructions, have regular check-ups, and seek prompt medical attention when discomfort occurs.
