Challenges and Complication Management in Novel Artificial Iris Implantation

Figure 8

Electron microscopic images of the edge of an artificial iris with embedded fiber meshwork (a). Outstanding sharp-edged fibers of the smooth silicon tissue are shown (arrows) caused eventually by use of a reusable trephine in this case. These could cause chronic bleeding in contact areas between the artificial iris and adjacent intraocular surfaces. (b) Smoothly trephined edge of an implant without embedded fiber meshwork with a single-use trephine.
