TechniqueRepairing iridodialysis by riveting with a double-flanged polypropylene suture
Section snippets
Surgical Technique
A 6-0 polypropylene suture is prepared in advance. The diameter of this suture is three times that of a 10-0 polypropylene suture, but it is less than that of the IOL haptic. Approximately 3.0 cm of the polypropylene suture is reduced into a small ball with heat applied using high-temperature cautery (Accu-Temp, Beaver-Visitec International, Inc.) (Figure 1, A). The ball is then flattened and widened with a needle holder (Figure 1, B). The polypropylene suture is cut to reach a length of
Discussion
There were no surgery-associated complications in any of the cases. We observed that the polypropylene not only dislocated the atrophic iris but also fixed and retained its shape (Figure 2). There is little possibility of the rivets falling out in the long term because they were thicker than 10-0 polypropylene; however, some risk does exist.
In cases of shorter iridodialysis, which require just one stich to be fixed, a double-armed suture is still useful; however, our technique is more useful
