“…Canabrava et al described a double-flanged 3-piece IOL haptic technique. 10 In this method, one of the IOL haptics is removed from the 3-piece IOL, and while one end is flanged and passed through the m-CTR or mCTS eyelet, the other end is taken out from the sclera and another flange is created. In their second study, the double flange is made by using a 5-0 polypropylene suture instead of the IOL haptic, and a CTS is used to support the dialysis area.…”

A new surgical technique was demonstrated for fixating the capsular bag to the sclera using a capsular tension segment (CTS) and a flanged iris hook. In a patient with a 180-degree zonular dialysis, a capsular tension ring was implanted into the capsular bag, and a CTS was placed into the zonular dialysis area after cataract removal. Then, an iris hook was directed to the anterior chamber through a side port opposite the zonular dialysis area. After the hook tip was placed into the eyelet of the CTS, a 30-gauge injector was used to guide the hook tip out. Tension was adjusted to ensure the capsular centralization, and a flange was created using cautery. Finally, the procedure was completed by embedding the flange into the sclera. This method is simple, minimally invasive, and time-saving by eliminating the scleral suturing, scleral flaps, or large conjunctival dissections.

“…After Yamane et al [ 12 ] reported his flanged intrascleral intraocular lens fixation with the double-needle technique, this technique has become more popularly used instead of suturing. Canabrava et al [ 13 , 14 ] reported the fixation technique for capsular tension segment: double-flanged polypropylene suture technique, and IOL repairing using four flanged. We also applied a technique for repairing iridodialysis by riveting with a double-flanged suture [ 6 ].…”

Repairing Cyclodialysis by Riveting: A Flanged Polypropylene Suture

Cyclodialysis causes intraocular lens (IOL) pupillary capture. It requires surgical repair to prevent this risk of IOL pupillary capture. However, since repairing cyclodialysis is often technically difficult, other methods such as barricading by suturing, pupilloplasty, and pars plana fixation of the IOL were preferred. We applied a double-flanged (riveting) technique for repairing cyclodialysis to prevent IOL pupillary capture following intrascleral fixation of the IOL. Cyclodialysis was surgically repaired by riveting with double-flanged 6-0 polypropylene sutures in 3 cases with no recurrence of pupillary capture during at least 12 months of follow-up. When pupillary capture is related to cyclodialysis, repairing cyclodialysis may help prevent pupillary capture after intrascleral fixation of the IOL. Riveting using a double-flanged 6-0 polypropylene suture could possibly make the procedure simpler and more efficient.

“…The haptic is threaded through the eyelet of a CTS and heated to create a flange that rests within the center of the eyelet. The other end of the haptic is externalized through the pars plana in the area of zonular weakness and flanged again with heat to allow for intrascleral fixation of the CTS [17]. Data on long-term stability of IOLs using this technique is still required.…”

Purpose of reviewThis review will focus on identifying causes of zonulopathy during cataract surgery and discuss various modalities for treatment. Recent findingsThere are multiple different options for capsular bag support in the setting of zonulopathy, including capsular or iris hooks, capsular tension rings as well as capsular tension segments (CTS). Surgical techniques on how to insert these devices are many and can be customized based upon the surgeon's preference and the patient's eye anatomy.
