There is no standardized time for discharging a patient from the hospital after retinal detachment surgery. The exact hospitalization time depends on the patient’s condition, and patients with mild conditions usually need to stay in the hospital for about a week. The causes and locations of retinal detachment vary. Some retinal detachments are mild and small in scope and do not involve critical areas such as the macula, so the surgery process is smoother and the recovery time is shorter. Patients with smooth surgery can be discharged from the hospital within a week or so, but they need to undergo regular checkups after discharge in order to avoid the recurrence of retinal detachment. If the retinal detachment is extensive or involves critical areas such as the macula, the surgery may be more complicated and the recovery time may be longer, and the patient may need to be hospitalized for a longer period of time. It is recommended that patients with retinal detachment seek prompt medical attention to assess their condition and follow the doctor’s instructions.
