Why is postoperative head positioning important and how long must it continue?
Patients are asked to remain in a certain position after surgery (usually face-down) if they have air, gas, or silicone oil in they eye. These materials rise to the highest point in the eye. If there have been retinal tears that have received laser or cryotherapy during surgery, the air, gas, or oil can help keep the tear closed, and the retina attached, while the laser or cryotherapy takes hold. Occasionally, head positioning is used to allow blood in the eye to settle away from the macula. The length of time varies, and your surgeon will tell you when it is safe to stop this special positioning.
