DecalineMate Insert

100% fluorinated liquid Perfluorocarbone

DecalineMateTM is a bicyclic
fluorocarbone compound with a
relatively high density (1.93g/cm3)
consisting only of C-C and C-F bonds
but not containing C-H or C=C double
bonds. Because of the outstanding
stability of the C-F bonds, DecalineMateTM
is chemically and physiologically
inert and absolutely untoxic.

Application

Perfluorodecalin serves perfectly in the
treatment of
•retinal detachments
•giant tears
•ocular trauma
•laser coagulation and cryotherapy
•lifting of subluxated lenses
•short term tramponade

Composition

•100% fluorinated Perfluorocarbone containing:
>95% Perfluorodecalin (isomers)
rest ad 100 consisting of (in declined quantity):
•Perfluoro-1, 2-diethyl-cyclohexane
•erfluoro-1, 2-dialkyl-cyclohexane
•Perfluoromethylhydrindane

Directions for use

After partial or complete vitrectomy
DecalineMate TM is injected above the
optical disk. The low viscosity allows
using standard instruments, e.g. blunting
needles of 20 to 23 G. In case of a giant
retinal tear, using care to avoid the
passage of the compound under the
retina. DecalineMate TM should be
completely removed at the end of the
retinoplexy or after a short-term
tamponade and if necessary exchanged
against a medium for long-term use.

Side effects

Due to its high gravity there is a
possibility that DecalineMate TM may
generate alterations of the retina if
present over a long period of time.
Therefore, the product should be left
in the eye for a short-term tamponade only.

How supplied

DecalineMate TM is available in volumes
of 5 and 7 ml.

Storage

The product should be stored at room
temperature.
