What is the difference between air and gas used during retinal detachment surgery?

During retinal detachment surgery, air or a medical gas may be placed inside the eye to help keep the retina in position while it heals. Air is absorbed faster than longer-acting gases, which can allow the view through the eye and everyday activities to recover sooner. Air usually absorbs within about 10 days, whereas some gases may remain for several weeks or longer. At First Samsung Eye Clinic, Dr. Sung-Jin Na prioritizes air tamponade when it is expected to provide adequate support after retinal traction has been released and subretinal fluid has been drained as completely as possible. Longer-acting gas or silicone oil may be more appropriate in complex cases or when prolonged internal support is needed.
