The present invention relates to a decompression- compensating instrument for use in intraocular surgery, wherein a perfusate is supplied to an affected part of an eye via a supply channel at a predetermined pressure, and the perfusate is aspirated via an aspiration channel together with the affected tissues that are to be removed, the decompression-compensating instrument supplying the perfusate into the affected part when the internal pressure of the affected part is excessively lowered, and being constructed so as to be connectable to a point midway along the supply channel and comprising a storage member that forms a chamber that is closable except for an opening from which the perfusate to be supplied to the supply channel flows, the capacity of the storage member being 7 cm3 to 22 cm3.
L'invention porte sur un système un instrument de chirurgie optique à décompression-compensation selon lesquels on instille dans l'oeil dans la partie concernée de l'oeil via un canal d'alimentation (51) et sous une pression définie. Alors que le liquide instillé est aspiré avec le tissu à éliminer par un canal ad hoc de manière à faire pénétrer ledit liquide dans la partie concernée alors que la tension oculaire est fortement abaissée. Ledit instrument, conçu pour se brancher sur la partie moyenne du canal (51), présente un réservoir refermable, d'où s'écoule par une ouverture le liquide alimentant le canal (51), et d'une capacité qui va de 7 cm?3¿ à 22 cm?3¿.
