Gas in eye | British and Eire Association of Vitreoretinal

The timing depends on the type of gas used: short-acting gas (sf6 gas) takes 2 to 3 weeks to disappear; long-acting gas (C3F8) takes about 2 months. When the gas bubble is down to half size, you will see a horizontal line across your vision, bobbing up and down with head movement. This is where the gas meets the fluid which is gradually replacing it.
