Abstract:
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.
