Experimental analysis of destructive ability of vacuum pulsation in cataract phacoemulsification

The purpose of the work. To evaluate the destructive ability of vacuum pulsation in cataract phacoemulsification. Materials and Methods. The experiments were performed on 40 separate pig eyes, in which cataract was induced in 3 stages of density according to the WetLab method. In the study group (n=20), phacoemulsification was carried out using a vacuum pulsation generation unit, in the control group (n=20) by the method of traditional ultrasonic phacoemulsification. For comparison of the two methods in both groups, the time of complete destruction of the lens fragment in seconds was recorded. Results. The average time of destruction of a 5x5 mm fragment of the lens, using vacuum pulsation was 23.6±4.9 seconds, for traditional ultrasonic phacoemulsification 17.7±8.9 seconds (p
