Puffing after retinal detachment surgery mostly refers to air or inert gas and usually takes about 1-2 weeks to absorb and stabilizes the condition in about 1 month, but the exact recovery time for the patient is related to the severity of the condition. There are two types of internal surgery after retinal detachment, one is silicone oil filling and the other is pumping. If it is clean air, it is usually absorbed by the retina within 1 week’s time. If the gas is inert, it takes about 2 weeks to recover and the patient can stand upright from the prone position. However, the patient does not recover completely after the gas is absorbed. The patient still needs to observe and pay attention to the protection after the operation, such as using tobramycin eye drops as prescribed by the doctor to prevent infection, paying attention to eye hygiene, avoiding airplanes, and avoiding spicy, stimulating and greasy food. The condition of most patients can be stabilized after 1 month, but the exact recovery time is related to the patient’s condition. It is recommended that after retinal detachment surgery, patients should follow the doctor’s instructions, have regular checkups, and consult the doctor in time when discomfort occurs.
