Double-flanged-haptic and capsular tension ring or segment for sutureless fixation in zonular instability.

PURPOSE

This paper introduces a surgical technique for the sutureless management of zonular dialysis greater than 120° using a capsular tension segment (CTS) or a modified capsular tension ring (m-CTR; CTR with suturing eyelets) and a haptic removed from a 3-piece polypropylene IOL.

METHODS

A CTR is used as normal. Cataract removal is followed by connection of the CTS or m-CTR to the single haptic and created using heat to make a flange in one haptic's extremity. The other extremity is placed in the CTS or m-CTR's central hole. The CTS or m-CTR/flanged-haptic complex is introduced into the capsular bag and aligned with the weakest zonular quadrant. A 30-gauge needle guides the externalization of the free haptic extremity through the adjacent pars plana and creates a flange on the second haptic tip permitting intrascleral fixation of the CTS or m-CTR.

RESULTS

The result is a successful IOL implantation with a sutureless technique.

CONCLUSIONS

This double-flanged m-CTR/CTS technique allows suture-free option for managing zonular weakness or dialysis while performing cataract surgery.
