title: Surgical strategies for the management of zonular compromise.
abstract: OBJECTIVE
  To evaluate new surgical treatment of zonular instability during cataract surgery.
  
  
  RESULTS
  The increased risk of complications associated with zonular compromise during cataract surgery has led to development of the capsular tension ring. More recently, the modified capsular tension ring and capsular tension segment have been introduced, allowing improved capsular stability and intraocular lens centration by scleral-suture fixation. Capsule support hooks also have a role in capsular stabilization.
  
  
  CONCLUSIONS
  When faced with zonular instability, the increased availability and use of capsular support devices allow for improved safety and outcome in cataract surgery.
