fluid-silicone exchange, air-silicone exchange, perfluorocarbon liquid-silicone exchange (the so-called direct exchange).
There are 3 surgical techniques to inject silicone oils into the eye: fluid-silicone exchange, air-silicone exchange, perfluorocarbon liquid-silicone exchange (the so-called direct exchange).
We do not perform a fluid-silicone exchange because, due to the low surface tension, we believe that the risk is too high that silicone oil enters the subretinal space through retinal breaks.
The commonly used fluid is silicone based fluid which ensures proper performance and stability.
Sequences are chosen to differentiate fat, fluid and silicone.
Hence it has been illegal to inject fluids like silicone into the body for cosmetic purposes since the late 60s, so these butt-pumping procedures are typically performed by back-alley quacks—rogue nut jobs with suitcases full of dirty needles and flasks full of muck.

Subsequently, the right internal jugular vein and carotid artery were catheterized, with single-lumen fluid-filled silicone catheters (S1UVC5.0, NeoCare; Klein-Baker Medical Co., San AnTXnio, TX, USA).
Here, we studied the acute effects of Askarel (which contains Aroclor 1260) and two substitute transformer fluids (the silicone oil-based DC561 and the mineral oil-based ENOL C) on rat testicular steroidogenesis.
The emulsification seems to be therefore time dependent [ 11] and it has been speculated that it depends on a combination of the saccadic motion, the difference in density of intraocular fluids and silicone oil, and the gradual decrease of interfacial surface tension of the oil due to the adsorption of surface-active components from the intraocular fluids [ 3, 8, 9].
