Active Fluidics
“Active Fluidics allow for better surgical IOP control than the standard gravity-based system during laboratory testing,” said Dr Mikhail Boukhny PhD,of the results of his team’s study,which was conducted in the US using an Alcon Centurium system.“We designed a system capable of very rapid pressure adjustments at the irrigation source,utilising feedback-based IOP target control rather than gravity-based system without feedback control.”
The study was performed in a laboratory simulated phacoemulsification model. Dr Boukhny,speaking at the XXI ESCRS Congress, explained that the system utilises a low-stretch, flexible polymercontainer that is squeezed within a computer-controlledmechanism to generate pressure.Optical-based, non-invasive pressure sensors in the irrigation and aspiration paths provide feedback for IOP control algorithms, allowing for very accurate pressure changes and precise control.
