title: Management of traumatic severely subluxated cataracts.
abstract: OBJECTIVE
  To determine outcome of cataract surgery in severely subluxated traumatic cataracts.
  
  
  METHODS
  Noncomparative case series.
  
  
  METHODS
  Retrospective review of cataract surgery in all consecutive eyes with at least 6 clock hours of zonulysis, for patient demographics, presenting best-corrected visual acuity (BCVA) and postoperative BCVA at various time points, extent of zonulysis, and type and timing of insertion of capsular tension device. Main outcome measures were retention of the capsular bag and BCVA at last visit. Secondary outcome measures included IOL stability and centration, and perioperative complications.
  
  
  RESULTS
  There were 41 eyes (41 patients). Mean age at time of surgery was 57 years and the mean duration of follow-up was 21.4 months. The capsular bag was preserved with aid of a Cionni modified capsular tension ring (CTR) in 36 eyes (87.8%) and a combination of a capsular tension segment (CTS) and CTR in 2 eyes. In 3 eyes with total zonulysis, the bag could not be preserved despite the use of a CTS in 2 eyes. Preoperatively only 9 of the 41 eyes (22.0%) had a BCVA of 20/40 or better, as compared to 38 eyes at the last visit (92.7%, P < .001, χ(2) test). Posterior capsule rupture occurred in 3 eyes, 2 of which occurred during fixation of the CTR.
  
  
  CONCLUSIONS
  The capsular bag can be successfully preserved even in severely subluxated traumatic cataracts with the aid of fixated capsular tension devices.
