When can I stop face-down positioning after a vitrectomy?

AAO says the length of face-down recovery is days to weeks and is determined by your surgeon, since it depends on your case. AAO's retinal detachment guidance mentions keeping the head in one position for a length of time such as 1 to 2 weeks.

The purpose is mechanical. AAO explains that the gas bubble floats, and recovering with your head down allows the bubble to float into the correct position against the part of the retina that needs support. Break that position for long stretches and the bubble drifts off the repair.

AAO is blunt about the stakes: your surgery may not work if you do not recover in the recommended position. That is why surgeons push so hard on this.

Positioning ending is not the same as the gas being gone. Many patients are released from positioning while a large bubble is still in the eye. The flying, altitude, scuba, and nitrous oxide restrictions run on the gas clock, not the positioning clock, and StatPearls puts that clock at about 5 to 7 days for air, 1 to 2 weeks for SF6, and 6 to 8 weeks for C3F8.

If positioning is causing you real problems, such as neck pain, breathing trouble, or you simply cannot keep it up, call the office rather than quietly quitting. Surgeons can sometimes adjust the instruction or the hours.
