Abstract
The invention relates to an interchangeable insert () for an ophthalmological medical device () for aspiration of fluid, such as for discharging fluid as part of suction flushing during an ophthalmo-surgical intervention, such as a cataract operation. According to the invention, this occurs by means of a fluid region () for receiving the fluid to be suctioned and a negative pressure region (), to which a negative pressure can be applied. The fluid region () and the negative pressure region () are hermetically separated from each other by an at least partially flexible membrane ().
