Entrapment of a Cionni ring hook by the pupil after suture rupture.

摘要

Cionni ring (CR) implantation is a procedure to correct limited lens subluxation in cases with Marfan syndrome, homocystinuria, Weill-Marchesani syndrome, and trauma. Although capsular tension ring implantation may be the solution for zonular weakness, it does not correct capsular bag decentration. Cionni ring implantation centers the intraocular lens (IOL), protects the capsular bag, and has few significant intraoperativeand postoperative complications 1 year after surgery. However, in a series of 90 eyes with CRs, Cionni et al. report an incidence of broken CR suture in 10% of eyes after a median follow-up of 18 months; 5 eyes required resuturing to recenter the IOL. Before this report, we had published our first 7 cases of phacoemulsification and CR implantation. One of our cases (case 3) has recently been checked, and a rupture of the suture was observed. The hook of this CR was entrapped by the pupil. To our knowledge, no similar CR complication has been reported.
