title: [Application of capsular tension ring in cataract surgery for zonular dialysis].
abstract: OBJECTIVE
  To evaluate the application of capsular tension ring (CTR) in the cataract surgery for zonular dialysis.
  
  
  METHODS
  Eleven cases of partially traumatized zonular dialysis patients were managed with CTR after continuous curvilinear capsulorrhexis (CCC), cataract extraction and posterior chamber intraocular lens (IOL) implantation.
  
  
  RESULTS
  The IOLs in all the eyes were basically in the normal position without tilting or obvious decentration. One month postoperatively, the best-corrected visual acuity (BCVA) was 0.4 in 4 eyes, 0.5-0.8 in 5 eyes and over 0.8 in 2 eyes. A side-by-side overlap of both eyelets of the ring happened in 1 eye due to the bigger diameter of CTR, and no other complications were seen except the original complication of cataract surgery.
  
  
  CONCLUSIONS
  For the patients of zonular dialysis, the CTR can preserve the integrity of the capsular bag, provide the necessary capsular space while giving a counter-traction, reduce asymmetric capsular forces, stabilize the vitreous base, facilitate phacoemulsification, aspiration of cortex and IOL implantation, prevent the postoperative IOL decentration and allow a quicker visual recovery. The CTR is a useful device that effectively supplements the currently available cataract surgery armamentarium, and develops the application of posterior chamber IOL implantation.
