Objective: To study the Infiniti Vision System phacoemulsification instrument (AJcon) phacoemulsification systems twist handle (ozil) and conventional phacoemulsification handle (ultra-soruc) in cataract surgery on corneal incision temperature. Methods: 40 freshly isolated porcine eyes were divided into 4 groups of 10, with the Infiniti Vision System phacoemulsification instrument (Alcon) Two systems handle (ultra-sonic and Ozil handle) for phacoemulsification surgery, conventional ultrasound energy is set to nonlinear energy 80%, twisting ultrasound swings set to 100%, flow rate 25ml/min, bottle height of 95cm, a negative pressure is 250mmHg, by way of clamping suction flow simulation phacoemulsification needle clogging state, respectively, in the blocked state and non-blocking state, measured with K-type thermocouple thermometer into three consecutive state foot stall cumulative time of 0,30,60,90 seconds corneal incision temperatures. Results: In non-blocking state, the conventional ultrasound group O, 30,60,90 sec temperatures were (26.O ± 0.6 ℃). (30.4 ± 1.1 ℃), (31.O soil 1.4 ℃), (32.2 ± 0.9 ℃), twist the ultrasound group (25.4 ± 1.3 ℃), (24.9 soil 1.O ℃), (25.2 ± 1.1 ℃) , (26.6 ± 1.O ℃). In blocking state, the temperature of the conventional ultrasound group were (26.3 ± 1_0 ℃), (39.2 ± 0.8 ℃), (41.1 ± 1.O ℃), (42.5 ± 1.2 ℃), the temperature of twist ultrasound group were (26.2 ± 1.1 ℃), (32.2 ± 0.8 ℃), (34.5 ± 0.9 ℃), (35.3 ± 1.1 ℃). In the non-blocking state and the blocked state, when the foot of the cumulative time entering three gears 60, 90 seconds, with the handle Ozil corneal incision surgery were significantly lower than the average temperature of the temperature of the conventional handle, the difference statistical significance (P <0.05).

 

Conclusion: Infiniti VisionSystem phacoemulsification instrument (Alcon) ultrasound system twist grip handle than conventional ultrasound heat production in fewer incisions, reducing the chances of corneal burns.
