Purpose: To show the modified scleral IOL fixation technique using a suture thread inserter combined with 25-gauge vitrectomy (DOC 2013).

Methods: Scleral fixation of the IOL was performed combined with 25-G vitrectomy. Instead of the making scleral tunnel or flap for being buried IOL fixation knot, we performed to make simply linear scleral incisions at 2- and 8-o’clock. Infusion cannula was inserted through the inferotemporal sclera and two cannulas were inserted through the scleral incision 1.5 mm posterior to the corneal limbus at 2- and 8-o’clock. After the vitrectomy, the looped part of the 10-0 polypropylene suture (PC-9: Alcon USA) was inserted at 2- and 8-o’clock port with suture thread inserter. The haptics of the foldable IOL were sutured by cowhitch method. Haptic externalization method was performed in the IOL dislocation eyes. After removing the infusion cannulas, 10-0 polypropylene were tied to linear scleral incisions.

Results: IOL fixation knots were buried in the linear scleral incision and the IOL was fixed stably.

Conclusions: This modified technique is safe and less invasive than the previous method which we presented at DOC 2013.
