Phaco surgery reconsidered
Driven by PACS (Phaco Assisted Cataract Surgery) and built on easyPhaco technology, OS 4 Up further elevates Oertli’s phaco competence.
Driven by PACS, built on easyPhaco technology
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
