Most of the information summarized in this section can be obtained from the instructions for use delivered with the medical device.
Microgases are high molecular weight gases intended to replace the vitreous humor in vitrectomy surgeries.
The average residence time in the eye varies depending on the gas used: SF6 1-2 weeks, C2F6 4-5 weeks, C3F8 6-8 weeks.
The device should only be used in sterile field by professionals. Gas should be inserted into the vitreous cavity after carefully removing the central and peripheral vitreous.
Pure gases should never be used alone, but it is always advisable to mix the gas with air; alternatively, already mixed gases can be used. The recommended mixing percentage is indicated on the syringe itself and is the same as that used in mixing with nitrogen.
The device is contained in a tyvek pouch along with accessories; pouch and contents are EtO sterilized. The gas contained in the canister is not sterile: accessories include a sterilizing filter, to be placed between the canister and the syringe when filling the gas syringe. See the image below for further clarification.
