Silicone oil removal for retinal detachment usually requires hospitalization, and the normal hospital stay takes about a week, but it depends on the patient’s condition. After a retinal detachment is detached, the patient may undergo surgery to reset the retina. If a vitrectomy is performed, silicone oil can be injected to better facilitate the recovery of the detached retina. However, silicone oil cannot be absorbed by the eye, and after the retinal detachment has healed, the patient will need to be hospitalized for a second surgery to remove the silicone oil to avoid complications. However, each patient’s condition is different, and hospital regulations vary from region to region, so the exact hospitalization time is related to the patient’s condition. It is recommended that postoperative retinal detachment patients follow the doctor’s instructions for care, regular checkups, and timely consultation when discomfort occurs.
