PACS: Adaptive phaco control
The OS 4 Up™ reconsiders phaco surgery. Building on proven easyPhaco technolgoy, PACS (Phaco Assisted Cataract Surgery) further elevates Oertli's phaco competence.
How PACS adaptively controls phaco energy
By detecting resistance at the phaco tip and adjusting energy delivery in real time, PACS contributes to precise, controlled and efficient work under stable chamber conditions*.
Why PACS stands out
«Reducing phaco energy, especially in the first steps of the phaco is a very important thing to have better results or less impact on the eye during surgery. For me, PACS is the most significant improvement of the OS 4 Up in the anterior segment surgery.» (D)

PACS works like
cruise control
The video explains PACS through a direct comparison of phaco tip behaviour with and without adaptive control. PACS detects resistance at the tip and adjusts energy delivery in real time to keep longitudinal tip movement constant*.
Use case:
Access to low power ranges
The extended control range in the low power range allows emulsification with finely dosed energy and controlled holdability. This is particularly beneficial when working with soft lenses*.
Emulsification with and without PACS
The video compares emulsification behaviour with and without PACS side by side. Emulsification with PACS appears more consistent and fluid behaviour appears more controlled.
Why PACS contributes to a smoother phaco workflow
«With PACS, we see less scatter from fragments during nucleus removal, resulting in shorter phaco times, which is already clearly noticeable.» (D)
