The fluorinated gases sulphur hexafluoride (SF6 ), hexafluoroethane (C2F6 ), and octafluoropropane (C3F8 ) are commonly used as intraocular tamponade agents in vitreoretinal surgery and are among the most potent greenhouse gases. There is significant waste associated with the use of large gas cylinders; the use of 30 mL canisters can lead to significant reductions in carbon emissions.
