Heat Generation and Efficiency of a New Modified Phaco Tip and Sleeve.

ABSTRACT:

Purpose

To compare a modified phacoemulsification tip with the established micro tip, in terms of temperature at the corneal wound, efficiency, and chatter events, using the Centurion® Vision system.

Methods

Eighty porcine eyes were randomized into 4 groups: 1)sleeveless conventional 45D MiniFlared ABS® Kelman tip (1.1-mm incision); 2)sleeveless new modified 45D ABS® INTREPID® balanced tip(1.1-mm incision); 3) Kelman tip with own sleeve (2.2-mm incision); 4)Balanced tip with modified 4-rib sleeve (2.2-mm incision). Measurements were taken with 2 settings: longitudinal(power 40% and 70%) and torsional mode (power 40% and 100%). Peak temperatures were measured 0, 10, 30, and 60 seconds after continuous ultrasound power. For the efficiency test, porcine lens nuclei were formali
