Dr. Boyer: Do you routinely use triamcinolone for visualization?

Dr. Kaiser: I have used triamcinolone acetonide injectable suspension (TRIESENCE, Alcon Laboratories, Inc.). I use TRIESENCE only for cases of posterior hyaloid traction with diabetes, where the vitreous is difficult to see. When I am working with fellows, I frequently inject Triesence—it is a great teaching tool because it enables clear visualization of the vitreous.

Dr. Rizzo: There are some cases, such as when a surgeon must differentiate an eye with vitreous schisis from a case of posterior vitreous detachment, for which triamcinolone must be used.

Dr. Boyer: Dr. Murray, can you discuss illumination?

Dr. Murray: The light source on the CONSTELLATION Vision System has four ports available for illumination. The new RFID technology recognizes a light probe when plugged into the system, so that when you plug an instrument into the port, the system prepopulates the settings for the correct light output. The ideal technology, in my opinion, is advanced, but I also want simplicity in the delivery, both of which the CONSTELLATION delivers.

Dr. Kaiser: Having multiple ports for lighting is a significant advantage because you can add a chandelier or another light source if needed, and the RFID ensures that the light output will be appropriate for 20-, 23-, or 25-gauge surgery.
