AdvanTec Legacy System and the NeoSoniX handpiece.

AdvanTec Legacy System and the NeoSoniX handpiece (Alcon Surgical, Fort Worth, Texas) are improvements to the Legacy System that allow power modulation and customization of surgical technique in phacoemulsification surgery. AdvanTec technology allows power modulation in terms of occlusion power management, global linear flow, mode sequencing, and visco mode. The NeoSoniX handpiece combines sonic oscillations with linear ultrasound to reduce thermal energy during nucleus removal. The AdvanTec System allows lower power, less delivered energy, a lower risk of thermal burns, less chatter, and improved followability during phacoemulsification. These improvements translate into successful clinical outcomes.
