• Currently there is high patient demand for fast
  visual rehabilitation after cataract surgery
• Fluidics play a crucial role during
  phaco-emulsification

3
Fusion TM Fluidics
CASE
Occlusion

• Incorporation of Occlusion mode CASE settings
• It is available in Signature phacoemulsification
  platform (AMO)

4
CASE concept
ChAmber Stabilization Enviroment

• CASE mode aims to lower vacuum to a preset level
  (case vacuum) before occurance of occlusion break.

5
This study is aimed to highlight the value of
optimized Fusion FluidicsTM settings during
Bi-axial MICS.

In Conclusion

• Fusion FluidicsTM enhances US efficiency during
  cataract surgery with modest power settings and
  higher flow rate and vacuum parameters.

14
In Conclusion
Given the high expectations of cataract patients,
Fusion FluidicsTM provides greater assurance of
rapid visual recovery Than k You
