A member asked:
How long after a vitrectomy does it take for the gas bubble to absorb and vision to return?
4 doctors weighed in across 3 answers
6-12 weeks: If the gas fill is 100%, the average rate of gas absorption is about 10%/week. Some patients will have complete resorption in 8 weeks and some as long as 12 weeks. Usually patients will begin to be able to see letters when the gas bubble is 45% or less (the macula is no longer covered by the gas that reflects light away). Best visual acuity is not realize until about 3 months after surgery.

Depends: That depends on the type of gas used. Usually it will take 1-4 weeks for the bubble to dissolve enough to allow sight to return centrally.

Reabsorption of gas: from the vitreous cavity varies per individual and depending on the type of gas used. Air can take 1-2 days while gas can take from 2-4 weeks.
