This ring is easy to use and very effective in managing patients who have IFIS. I use it often with confidence to help perform successful cataract surgery

Richard W., MD, United States

Have used this product in several situations, including IFIS, inadequate dilation, small pupils secondary to trauma(p. syn.). It works well consistently and has helped prevent complications in many cases.

The ring is easy to insert and to remove. Works well to maintain a stable iris with an adequate pupillary size for safe phacemulsification.
