Intervention / Comparator Agent
|
| Type |
Name |
Details |
| Intervention |
Centurion Vision System |
The Centurion uses Active Fluidics feedback to compensate these flow variations so that the surgical IOP is more constant in the steady state.1 2
The Centurion also has less transient variations, especially after occlusion break 1 3
The Quadrant removal settings normally utilizes the most aggressive vacuum settings and is s good step to compare system performance
|
| Comparator Agent |
Infiniti vision system |
In traditional phaco systems, surgical IOP changes with variations in aspiration flow( Infiniti) |

Brief Summary
|
To measure Realtime, Dynamic, Intraocular Pressure during microaxial phacoemulsification using the Centurion Vision System and the Infiniti vision system Prospective, Randomized, Clinical Study: Based on a peer-reviewed method. an IOP measuring sensor will be introduced through a 1.2mm paracentesis incision during the surgery. This will be connected to an IOP transducer, then received and amplified, then converted into digital signals (via Picoscope). A video mixer will then overlay the input from the laptop and from the surgical overlay, and will allow simultaneous visualization of real-time IOP, along with the parameters being used during surgery. Likewise, this same test will be done on the Alcon Infiniti system. Mean IOP values and peak-to-peak variations will be recorded Total patients: 40 maximum (20 per group) |
