These rings and their workings look similar, but there are 2 key
areas of difference between them. Depending on the number of points
of contact with the margins of the iris, some rings may make the dila-
tion more round and others more square. In addition, each has its
own insertion and removal device. Some physicians may find that a
particular device, and its unique manner of operation, works better
than others. This could be a critical deciding factor. While they can
probably get comfortable working with any ring during a case, the
ability to easily insert and remove that ring is essential to an efficient
process.
