Purpose: The aim of this study is to review the usage of capsular tension rings during phacoemulsification Methods: Patients who underwent phacoemulsification and had capsular tension ring inserted during this procedure were identified from the theatre records during the periods 2001–2004. Details were obtained on sociodemographic variables of the patients, indications for the usage of the tension ring (i.e clinical findings predisposing to zonular weakness) biometric variables, intraoperative complications, type of ring utilised and postoperative capsular bag and intraocular lens implant (IOL) stability. Results: 20 eyes were identified that fulfilled the criteria of inclusion. 9 male and 11 females of mean age 74 were identified . The commonest indication for the usage of the tension ring was preoperative identification of zonular weakness (80%) such as pseudoexfilation syndrome and traumatic cataracts. In only a very small proportion of the cases (1%) there was intraoperative complication with vitreous loss. At the first postoperative visit all cases were judged to have a well centred stable posterior chamber IOL. Conclusions: This is a retospective study showing good results with the use of the capsular tension ring in cases where the preoperative examination suggests zonular weakness.
