Driven by PACS (Phaco Assisted Cataract Surgery) and built on easyPhaco technology, OS 4 Up further elevates Oertli’s phaco competence.
Chamber stability
- Fluidics based on physics is the principle behind our technology
- Irrigation capacity is significantly higher than aspiration
Result: stable anterior chamber4
Magnet-like attraction
- High vacuum and irrigation create a direct flow to the tip opening
- No chasing fragments as material moves toward the tip
Result: fragments come to your tip*
Occlusion is our friend
- Irrigation controls stability after occlusion break
- Angled tip opening firmly holds fragments
- Strong holdability and steady occlusion
Result: occlusion provides control
PACS – Phaco Assisted Cataract Surgery
- Contributes to a precise, controlled and efficient performance under occlusion
- Adaptive phaco delivery keeps longitudinal tip movement consistent regardless of nucleus hardness
- Detects when dense material restricts the tip and instantly adjusts energy delivery
- Unlocks finely dosed energy in newly accessible low-power ranges
Result: with PACS you achieve confident phaco performance under calm conditions
U/S energy absorbed by the fragments
- Ultrasound is longitudinally directed into occluded fragment
- Capillary aspiration path and high vacuum settings provide continuous aspiration after occlusion break
Result: a symphony of PACS and modern fluidics
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*.
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*.
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*.
«With PACS, we see less scatter from fragments during nucleus removal, resulting in shorter phaco times, which is already clearly noticeable.»D1

The easyPhaco technology is developed for safe and efficient phacoemulsification. It is characterised by direct fragment followability, strong holdability and a stable anterior chamber.
Proper hydrodissection: Only a proper hydrodissection releases the lens until it can be fully rotated. Once mobile, you can use your preferred technique to start, stop and chop, divide and conquer or direct chop.
Turn the bevel sideways: Rethink your habits: Turn the bevel sideways to reach full occlusion. Holding the bevel at 11 or 1 o'clock towards the fragment provides high performance.
Stay in the center: easyPhaco allows you to work at a safe distance from the capsular bag. The high vacuum setting and the wide infusion path of the easyTips create a direct flow to the tip. This results in a magnet-like attraction of the fragments while the capillary aspiration path porvides continuous aspiration.
The OS 4 Up is designed to ease the cognitive load of managing equipment, instrumentation and settings during delicate procedures. This supports focus, confidence and ease, so you can enjoy surgery.
