Retinal detachment surgery usually requires a hospital stay of about a week, depending on the circumstances. Since each patient’s condition and physical condition are different, the hospitalization time will also vary. On the first day of hospitalization, blood tests such as routine blood tests, coagulation function, blood glucose, liver function, kidney function, etc., as well as electrocardiograms and chest X-rays, etc., will be done to check whether there are any indications that the patient is not suitable for surgery. If the above tests are normal, surgery can usually be scheduled for the next day, and about 3 to 5 days of observation will be needed after surgery. If the retina is well reset, the patient can be discharged after the operation with smooth recovery, which usually takes about one week. However, if the patient’s physical condition is poor, the patient’s hospitalization can be relatively longer. It is recommended that patients after retinal detachment surgery follow the doctor’s instructions for care, regular checkups, and prompt medical attention when discomfort occurs.
