General description of the device

Microgases are high-molecular-weight gases intended to replace the vitreous humor, present in the eyeball, in surgeries in which the eyeball must be removed.

In less complicated cases the vitreous is not replaced, while at other times it must be replaced with a so-called “vitreous substitute.”

After surgery, Microgases remain inside the eye for different times 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.


The main contraindications are for use by health care providers.

Patients who have undergone Microgas surgery must strictly adhere to the instructions they were given at the hospital. They must also keep the implantable card and show it whenever they go to the hospital, they must notify the anesthesiologist immediately if they have to undergo anesthesia, local or general.

He must also wear the patient bracelet on his wrist at all times, which lists the main correct behaviors to be followed, such as avoiding pressure surges, as in the case of air travel, scuba diving, hiking in the mountains, excessive exertion and temperature changes.
