Abstract

The present study describes a surgical technique for the management of complex dislocation and subluxation of the intraocular lens (IOL)-capsular bag (CB)-capsular tension ring (CTR) complex. During the procedure, one double-curved suture was inserted through the sclera into the posterior chamber, passing through the anterior capsules and then into the anterior chamber. The suture lines were pulled out from above and below the IOL-CB-CTR complex and a knot was tied 1 mm away from the corneoscleral incision. The IOL-CB-CTR complex was repositioned by adjusting the suture length. This novel method does not require explanting of the original IOL, allowing the IOL-CB-CTR complex to be immobilized in a simple and effective way.

Keywords: dislocation; intraocular lens-capsular bag-capsular tension ring complex; subluxation; suturing.

Dislocation of the IOL-capsular bag-CTR complex. One end of the CTR as well as the haptic of the IOL is visible (arrow). CTR, capsular tension ring; IOL, intraocular lens.

Suturing of the IOL-CB-CTR complex. Left panel: A corneoscleral incision is made and a needle with a 10-0 polypropylene suture (black arrow) is passed through the sclera to reach the IOL-CB-CTR complex. Middle panel: A suture (black arrow) is wrapped around the tangential contact point of the IOL haptic and the CTR. Right panel: The IOL-CB-CTR complex is repositioned to the center of the pupil (black cross). CTR, capsular tension ring; IOL, intraocular lens; CB, capsular bag.
Figure 3.
Figure 3.
A 10-0 polypropylene suture is hooked perpendicularly around the tangential point of the IOL haptic and the capsular tension ring. Through a 1-mm corneoscleral incision, a Z suture is formed and tied, leaving no sutures penetrating the corneoscleral limbus. IOL, intraocular lens.

At the one-year follow-up, the capsular tension ring and intraocular lens remain in the middle of the pupil and no further dislocation had occurred.
