DEVICE FOR OPHTHALMIC SURGERY, IN PARTICULAR FOR CATARACT REMOVAL, PROVIDED WITH A SYSTEM FOR DYNAMICALLY MAINTAINING INTRAOCULAR PRESSURE

摘要

The present invention relates to a device for ophthalmic surgery, in particular for cataract removal, with intraocular pressure (lOP) stabilisation, comprising an irrigation line (5), within which an irrigation fluid flows, having an end portion capable to irrigate an eye, characterised in that it comprises at least one first source (6; 17) of irrigation fluid at a first pressure value connected through valve means (7; 18) to said end portion of the irrigation line (5), said valve means (7; 18) being controlled by control means (12) o n the basis of a pressure detection provided by pressure sensor means (9; 20) connected to said end portion of the irrigation line (5) and capable to sense an intraocular pressure (lOP), whereby said control means (12) opens said valve means (7; 18) when the pressure sensed by said sensor means (9; 20) is not higher than a second pressure value not higher than the first pressure value, thus putting said at least one first source (6; 17) in communication with said end portion of the irrigation line (5).
