title: Perforation rosette of the lens after Nd:YAG laser iridotomy.
abstract: OBJECTIVE
  To describe an unreported complication of Nd:YAG laser iridotomy.
  
  
  METHODS
  We examined a 31-year-old patient with pigment dispersion syndrome and moderately increased intraocular pressure whose left eye had been treated prophylactically with Nd:YAG laser iridotomy and who complained of blurred vision thereafter.
  
  
  RESULTS
  Slit-lamp examination of the left eye disclosed a typical perforation rosette of the posterior pole of the crystalline lens with a perforation of the anterior lens capsule under the iridotomy site and pigment within the lens. Opacity regressed spontaneously, and vision returned to normal.
  
  
  CONCLUSIONS
  A perforation rosette of the lens can occur after Nd:YAG laser iridotomy and should be considered a possible serious complication of the procedure.
