title: Identification of retained nucleus fragment in the posterior chamber using ultrasound biomicroscopy.
abstract: OBJECTIVE
  To describe the use of ultrasound biomicroscopy (UBM) to image retained nuclear fragments posterior to the iris plane after uncomplicated phacoemulsification with posterior chamber intraocular lens (PCIOL) implantation in two patients.
  
  
  METHODS
  Interventional case report.
  
  
  METHODS
  Two patients presented with an iris elevation after uncomplicated phacoemulsification and lens implantation.
  
  
  RESULTS
  Visual acuity was 20/20 in the first patient and 20/30 in the second. There was no anterior chamber inflammation in either eye. UBM revealed a small, retained nuclear fragment between the iris pigment epithelium and the anterior lens capsule, causing localized anterior iris displacement in both patients. The PCIOL was within the capsular bag, and the iris root and ciliary body were normal in both patients.
  
  
  CONCLUSIONS
  UBM can demonstrate retained lens fragments within the posterior chamber.
