[Ophthalmic operating theatre--chance of limiting contamination and infection risk. Part I. Decontamination of the microbial air pollution].

: Even the best technical and organizational methods will not prevent the infection of the spot being operated on. The risks may be caused for example by the microbial air pollution of the operating theatre. Ways of air decontamination for the purposes of air conditioning and ventilating used in the operating theatre are both up-to-date and essential. Decontamination methods involve filtration by means of HEPA, ULPA, EU-13 filters with 99.99% effectiveness for 0.003 um which include cells of bacteria, fungi and some viruses. MFI technology used in Nanobio E 310 (Genano) working at 250 m3/h allows for eliminating microorganisms from the air at < or = 1 cfu/m3. These decontamination methods make it possible to achieve appropriate microbiological standards when the appliance is properly used.
