Staining with trypan blue and retroiridian synechiolysis

effective approach in cataract surgery for patients with chronic uveitis, severe miosis, and posterior synechiae

Abstract

The novel technique of “staining and retroiridian synechiolysis” emerges as an effective alternative to overcome challenges associated with anterior capsular staining and pupillary synechiolysis in patients with chronic uveitis, characterized by severe miosis and posterior synechiae. This technique involves initially performing a minimal peripheral iridectomy to access the retroiridian space and injecting trypan blue for complete staining of the anterior lens capsule. Subsequently, viscoelastic is applied in the anterior chamber, and synechiolysis is performed using an iris repository spatula through the iridectomy site, effectively reducing surgical time. The successful implementation of this technique has facilitated uncomplicated surgery initiation, demonstrating its potential as a viable alternative for these challenging cases.
