Intraocular Suture Looping Technique for Flapless Four-Point Refixation of Dislocated Intraocular Lenses

Figure 1

Schematic figure of the intraocular looping technique for four-point fixation (drawn by Haiying Jin). This figure is authorized to be published by the present journal to demonstrate the surgical procedures. (a) The looping needle is externalized from the first fixation point and loaded with an 8–0 polypropylene thread in its lumen (arrow). Red arrows show the needle path from the eyelet of the IOL to the sclerotomy. (b) After loading the thread, the looping needle is recoiled into the anterior chamber and passed through the following paths: the first eyelet of the IOL, the second eyelet of the IOL, and ab externo pass through the second sclerotomy (red arrows). The thread in the lumen of the needle is finally pulled out (black arrow). A suture loop is created passing through both eyelets on the same side. (c) After the intrascleral passing (arrow 3) of the thread from the first fixation site to the second fixation site, a double knot technique is performed for a flapless IOL fixation. The first overhand knot in the sclerotomy (arrow 2) is used for the IOL fixation. The second knot (1) is used to lead the ends of the threads for burying in the sclera.
