“…The solution has a viscosity of 3300 mPas, interfacial tension > 40 mN/m and a density of 1.03 g/cm 3 , just above the level of aqueous humor, which is resulting in a relatively weak gravity effect that comes close to floating. Clinical data on the use of Oxane HD are available from 9 single-centre institutional case series [1,4,5,9,19,20,27,29,30] 3 covering a total of 211 treated eyes. There is one randomized observation available comparing Oxane HD with 1300 mPas silicone [4] in which, unfortunately, the number of treated cases is far below a critical limit necessary to allow a statistically reasonable conclusion.…”
