abstract: OBJECTIVE
  To analyze the experience and curative effect in treating chronic dacrocystitis by dacryocystorhinotomy with Ho:YAG laser under endoscope.
  
  
  METHODS
  20 patients of chronic dacryocystitis were treated by dacryocystorhinotomy with Ho:YAG laser under endoscope, followed-up for 1 approximately 2 years to observe the curative effects.
