Ophthalmological aspiration and irrigation system

An aspiration and irrigation system, in particular for performing surgical operations on an eye of a living being to maintain the intraocular pressure, comprising:

• a pressure unit for supplying a gaseous fluid to the eye via a first fluid passageway;
• infusion means for providing a liquid fluid, said infusion means including a first infusion bottle containing a liquid fluid at a fluid level in substantial alignment with the eye and a second infusion bottle arranged at a distance above and connected to said first infusion bottle via a dropper for allowing a flow of liquid fluid from said second infusion bottle to said first infusion bottle;
• irrigation means communicating with said first infusion bottle for conducting liquid fluid from said first infusion bottle to the eye via a second fluid passageway, said first infusion bottle communicating with said pressure unit via a third fluid passageway for introduction of gaseous fluid above the fluid level;
• valve means set in a fluid passageway between said irrigation means and said pressure unit on the one hand, and the eye on the other hand for selectively conducting the flow of fluid from said irrigation means and said pressure unit to the eye through said first and second fluid passageways;
• and,
• aspiration means for removing fluid and/or tissue from the eye.
