The present invention relates to fluoroalkyloxy alkanes having formula (I) : RF-R1-O-R2 wherein: RF is a linear or branched perf luoroalkyl group, having from 1 to 12, preferably from 2 to 8, carbon atoms; R1 is a linear or branched, non-fluorinated alkylene group, having from 1 to 6, preferably from 2 to 4, carbon atoms,- R2 is a linear or branched, non-f luorinated alkyl group, having from 1 to 12, preferably from 2 to 8, carbon atoms, possibly containing at least one ether bond -O- along the chain. The present invention further relates to a process for preparation and use thereof, possibly in mixture with at least one silicone oil, as medicaments in ophthalmology, in particular as tamponade liquids in an operation for the treatment of retinal detachment.

with general formula F(CF2)mCH2CH2O(CH2)nH (m = 4, 6, 8 and n = 2, 3, 5, 8, 14, 18, 21) has been synthesized and characterized. The present work aimed to investigate the synthesis of PFE-m,n and evaluate some of their fundamental physico-chemical properties such as: specific gravity, refractive index, viscosity, solid–solidtransitions, solubility and amphiphile surface activity in a variety of solvents
