Irrigation/Aspiration
Aspiration flow is necessary to remove the emulsified cataract material from the
eye. An irrigation supply is necessary to replace fluid removed by aspiration of
cortical material and fluid lost to leakage from the incision.
This fluid balance maintains the anterior chamber during surgery. Irrigation is
controlled by gravity.
The flow rate of irrigation solution through the irrigation sleeve on the phaco tip is
determined by the height of the drip chamber (head pressure). The drip chamber
hangs from the bottle on the Programmable IV Pole. AMO recommends that at the
start of a procedure, the irrigation solution level in the drip chamber be located
approximately 65–70 cm above the patient's eye level. To increase irrigation
pressure, the IV bottle is raised. To decrease pressure, the bottle is lowered.
