·AIM:To compare the clinical efficacy of implantation of lead-type silicone tubes combined with or without laser treatment for lacrimal duct obstruction.METHODS:The patients were randomly divided into two groups,one group were implanted with lead-type silicone tube only(A group);another group underwent the laser treatment combined with implantation of lead-type silicone tube(B group).RESULTS:The cure rate of lead-type silicone tube implantation for lacrimal duct obstruction was 77.6%,the cure rate of laser treatment combined with lead-type silicone tube implantation for lacrimal duct obstruction was 87.5%.CONCLUSION:The laser treatment combined with lead-type silicone tube implantation has a higher cure rate of lacrimal duct obstruction,and more obvious advantages.
