ObjectiveThe present study intends to evaluate the effectiveness of a standardized cleaning process with negative pressure suction in cleaning phacoemulsification handpieces.MethodsSixty phaco handpieces requiring post-operative cleaning were randomly divided into the experimental groups using standardized cleaning or manual cleaning, and the control group receving no clearing treatment. In the standardized cleaning group, a negative pressure suction device and a pressure water gun were used to clean the lumen. In the manual cleaning group, the suction port and perfusion port of the handpiece were cleaned by a syringe. The cleaning effect was visually evaluated using a magnifying glass with light resources, and enzyme residue was detected by adenosine triphosphate (ATP) bioluminescence assay.ResultsThe cleaning time of the standardized cleaning group was significantly less than that of the manual cleaning group. The standardized cleaning time decreased as the negative pressure value increased. The optimal negative pressure range was 0.03Mpa to 0.05Mpa.ConclusionA negative pressure suction device can effectively save the cleaning time of the phaco handpiece. Thus, standardized phaco handpiece cleaning process with a negative pressure suction device can improve cleaning efficiency.
