Laser plasty combined with nasolacrimal duct stent implantation for nasolacrimal duct obstruction

Objective To observe the effects of laser plastic operation combined with nasolacrimal duct stent implantation in treatment of nasolacrimal duct obstruction.Methods We chose 88 eyes of 85 patients of nasolacrimal duct obstruction for treatment of laser plastic operation combined with nasolacrimal duct stent implantation.They were followed up for 6 months.Results A total of 86 eyes were successfully implanted nasolacrimal duct stent.Two eyes were failure in laser probing.The success rate in 1,3 and 6 months were 95.45 ％,85.23 ％ and 81.18 ％ successively.Conclusion Laser plastic operation combined with nasolacrimal duct stent implantation is a simple,safe and effective treatment method for nasolacrimal duct obstruction.
