title: Double-ring and double-layer sign of the anterior lens capsule during cataract surgery.
abstract: BACKGROUND
  Splitting of the lens capsule with a double-ring contour during continuous curvilinear capsulorrhexis has not often been reported.
  
  
  METHODS
  An 86-year-old woman underwent phacoemulsification cataract extraction with intraocular lens implantation in the right eye. Preoperatively, the anterior lens capsule appeared normal.
  
  
  METHODS
  A double-ring sign was observed during capsulorrhexis. During intraocular lens implantation, the capsule developed radial tears, and a double layer of the capsule was noted. The patient's postoperative course was uneventful.
  
  
  CONCLUSIONS
  The findings in our patient may be uncommon and may differ from but resemble true exfoliation.
