AIM:To observe the clinical effect of joint implantation of straight silicon tube and spherical headed silicon tube in treatment of post-operative patients with recurrent chronic dacryadeitis.

METHODS:Forty-nine patients(50 eyes)with recurrent chronic dacryadeitis who had treated with straight silicon tube or spherical headed silicon tube were implanted with straight silicon tube combined with spherical headed silicon tube.Patients were followed up for 1a to observe the curative effect.

RESULTS:The operation was invalid in 5 cases(5 eyes)as their rigation of lacrimal passage was failure.The remaining 45 eyes in 44 cases were cured with no epiphora.The cure rate was 90% at 1a after the tubes were extracted.

CONCLUSION:The joint implantation of straight silicon tube and spherical headed silicon tube is an effective and safe technique in treatment of post-operative patients with recurrent chronic dacryadeitis,and worthy of widely use in patients with chronic dacryadeitis who have never been treated with surgeries.
