Abstract
A irrigation/aspiration apparatus to be used in a cataractal operation comprises an irrigation fluid supply means for supplying an irrigation fluid contained in an irrigation bottle to the patient's eye, and an irrigation fluid aspirating means for aspirating, together with loosened tissues and the like, the irrigation fluid supplied into the patient's eye. The irrigation/aspiration apparatus is characterized by an irrigation flow rate varying means for varying the irrigation rate of the irrigation fluid at which the irrigation fluid supply means supplies the irrigation fluid, and an irrigation flow rate control means for controlling the irrigation flow rate varying means according to the operating condition of the irrigation fluid aspirating means to regulate the irrigation flow rate so that the variation of the pressure in the anterior chamber of the patient's eye is suppressed during the cataractal operation.
