A novel iridoplasty suture technique to repair iris defects and traumatic mydriasis

A new iridoplasty method is described, which uses the U-suture technique to repair traumatic mydriasis and large iris defects. Two 0.9 mm opposing corneal incisions were made. The needle was inserted through the first incision, passed through the iris leaflets, and removed through the second incisio...

Description
Summary:A new iridoplasty method is described, which uses the U-suture technique to repair traumatic mydriasis and large iris defects. Two 0.9 mm opposing corneal incisions were made. The needle was inserted through the first incision, passed through the iris leaflets, and removed through the second incision. The needle was reinserted through the second incision and removed through the first incision by re-passing the needle through the iris leaflets to form a U-shaped suture. The modified Siepser technique was applied to fix the suture. Thus, with a single knot, the iris leaflets were brought closer (shrinking like a pack), fewer sutures were used and fewer gaps were left. Satisfactory aesthetic and functional results were obtained in all cases in which the technique was applied. There was no suture erosion, hypotonia, iris atrophy, or chronic inflammation during the follow-up.
