Alcon Centurion Versus Alcon Infiniti Phacoemulsification machines
In 2014 I started using the Alcon Centurion phacoemulsification machine instead of the Alcon Infiniti machine. The change was smooth but there were a few small adjustments that had to be made.
The main adjustments to be made were as follows:
A. Differences in the Foot pedal.

If I had the choice, I would have kept the Infinity foot pedal and put up with a chord attaching to the new Centurion.
B. Bimanual cortical aspiration
Ultraflow Bimanual I/A, versus Alcon 0.3mm Polymer I/A, versus Medicel Bi-Manual hand pieces. (Pic 3) For three years I have used the disposable Ultraflow bimanual aspirator and infusion cannulas.The instrument pass nicely through a 1.2 mm paracentesis.I have been very happy with them but in late 2014 there seemed to be a continuous disruption in supply. I was then offered the choice of the new Alcon 0.3 Polymer I/A bimanual set and the Medicel 21G Bimanual set. |
My thoughts are as follows:

My feeling is that the Ultraflow is the safest and most efficient of these products, followed closely by the Medicel bi-manual set.
There is a bimanual set labelled SBS105 also made by Medicel. It is almost identical to the one reviewed above being the Medicel SBS110A.
Although the two bimanual sets look identical, with the same colour hand-pieces and identical packaging there is a difference that may catch the unwary. The SBS105 model has a very blunt irrigation port that does not fit through the 1.2mm paracentesis. One then finds oneself trying to force this blunt tip through an incision that is simply to small. The best is then to slightly open the incision with a blade to allow the irrigation port into the eye. This decreases the risk of stripping descements membrane or traumatising the wound. The next step would be to inform the theatre staff that the SBS110A should be ordered and not the SBS 105.
. So how does integrity differ from chYarcter?aou said that a person of integrity would have high character. I’ve always defined the words as being essentially the same — is there a difference?
