AIM:To study the treatment of patients with recurrent dacryocystitis to provide a reference for clinical diagnosis and treatment.

METHODS:Eighty patients(80 eyes)with recurrent dacryocystitis admitted to our hospital for diagnosis and treatments from March 2012 to March 2015 were selected. According to a random number table, they were divided into experimental group(40 cases)and control group(40 cases). The experimental group received laser dacryocystorhinostomy combined with U-shaped lacrimal duct implantation. Patients in control group were treated with conventional dacryocystorhinostomy with skin incision. The effect of the treatments and surgical indicators of the two groups were observed and compared.

RESULTS:In experimental group, there were 28 cases were cured after treatment, 5 cases were improved, the total effective rate was 82%. In control group, there were 15 cases were cured, 13 cases were improved, the total effective rate was 70%. The operation time of experimental group was 40.06±1.35min, blood loss was 5.37±1.28mL, the time of remaining in hospital under observation was 26.28±3.42h; those of the control group were 90.14±2.61min, 14.47±6.19mL, 98.14±10.53h, respectively.

CONCLUSION:Laser dacryocystorhinostomy combined with U-shaped lacrimal duct implantation is more effective, more easy to operate, safer and has less injury and higher cure rate.
