Early Experience with the CONSTELLATION Vision System

I have used the CONSTELLATION Vision System for approximately 10 cases and overall, I have found it to be a sophisticated vitrectomy system.We have found that the setup and interaction between the scrub nurses and the machine is more efficient than with previous vitrectomy systems that we have used.

The small-gauge instrumentation on the CONSTELLATION System may have a role for pediatric population due to the smaller working spaces in child eyes. The improved suction and manipulation are helpful for surgeries in both adults and children. In the pediatric cases that I perform, I am usually dealing with heavy and opaque tissue, so I prefer to take individual bites of tissue rather than use the high cutting rates. I do use higher cutting rates, however, when I am dealing with clear vitreous.

The duty cycles on the CONSTELLATION System are helpful for working on a mobile retina, but in pediatric retinal detachments the retina is often stiff. I am more likely to use the duty cycle feature on adult cases.

The illumination on the CONSTELLATION System is good.The light is clean and bright, the instruments are simple to hook up, and the light intensities can be easily monitored by the scrub technicians.

I have limited experience with this system, but look forward to this small-gauge vitrectomy system for more of my patients.
