The needle was inserted into the anterior chamber from the sclera 2.0 mm behind the corneal limbus parallel to the iris, and the 23-G anterior forceps were used to assist the needle tip puncture through the root of the detached iris. Back off the needle and lead out one side of the suture that passes through the iris to the outside of the eye.

The needle was inserted into the anterior chamber from the sclera 2.0 mm behind the corneal limbus parallel to the iris, and the 23 G anterior forceps (Belle Healthcare Technology Co, Ltd) were used to assist the needle tip puncture through the root of the detached iris, and the 7-0 polypropylene thread was clamped with 23 G forceps and inserted into the 30 G needle tube (Figure 1).
The needle was withdrawn, and the suture was taken out of the eye. The same procedure was repeated to guide the other arm of the suture through the iris and out of the eye.

The other side of the suture remains in the anterior chamber (Figure 2).
The suture was tightened to make the iris root adhere to the corneal limbus.

The same procedure was repeated, and the other end of the suture was passed through the iris and out of the eye (Figure 3).
After cutting the suture, it was cauterized into a flange and inserted in the sclera for fixation.

Each end of the suture was flanged and shortened using high-temperature cautery until the flange reached the sclera (Figure 4).
