title: Modified capsular tension ring implantation in eyes with traumatic cataract and loss of zonular support.
abstract: OBJECTIVE
  To evaluate the outcomes of implantation of a Cionni modified capsular tension ring (CTR) and a posterior chamber intraocular lens (PC IOL) in patients with traumatic cataract and loss of zonular support.
  
  
  METHODS
  Eye Clinic II, Haydarpasa Numune Education and Research Hospital, Istanbul, Turkey.
  
  
  METHODS
  Case series.
  
  
  METHODS
  Eyes with traumatic cataract and loss of zonular support had phacoemulsification with implantation of a foldable IOL and a 1- or 2-eyelet modified CTR. Preoperative features, preoperative and postoperative corrected distance visual acuity (CDVA), intraoperative performance, IOL position, and complications were evaluated.
  
  
  RESULTS
  The study enrolled 16 eyes (16 patients). The mean CDVA was 0.89 logMAR ± 0.41 (SD) preoperatively and 0.33 ± 0.43 logMAR at the last postoperative examination (P=.001). Postoperatively, the mean spherical equivalent was -0.23 diopter (D) (range -1.50 to +1.00 D) and the mean postoperative astigmatism, 1.59 D (range 0.50 to 4.00 D). Eight eyes (50.0%) had phacodonesis preoperatively; no eye had pseudophacodonesis postoperatively. Preoperatively, 10 eyes (62.5%) had symptomatic decentration. Two eyes (12.5%) had asymptomatic nonprogressive decentration in the early postoperative period; no eye had symptomatic decentration throughout the follow-up. Three eyes (18.8%) preoperatively and 1 eye (6.2%) postoperatively had vitreous in the anterior chamber. Four eyes (25.0%) required anterior vitrectomy. Other complications were symptomatic posterior capsule opacification in 8 eyes (50.0%) and transient increased intraocular pressure in 2 eyes (12.5%).
  
  
  CONCLUSIONS
  The use of a modified CTR preserved the capsular bag and resulted in good PC IOL centration with few significant complications in patients with traumatic cataract and loss of zonular support.
