title: Suture refixation and recentration of a subluxated capsular tension ring-capsular bag-intraocular lens complex.
abstract: We describe a 3-point ab externo technique to refixate and recenter a subluxated Cionni capsular tension ring (CTR)-intraocular lens (IOL)-capsular bag complex to the sclera. A 9-0 polypropylene suture on a curved needle is looped through the eyelet of the CTR and back through a Hoffman scleral tunnel. Two other sutures passed in a similar fashion through the fibrotic continuous curvilinear capsulorhexis (CCC) edge are used to complete a tripod fixation, which centers and stabilizes the IOL. This surgical approach avoids the surgical trauma of removing and replacing a subluxated CTR-IOL-capsular bag complex, retains the optimal anatomical position, and ensures centration of the IOL.
