AIM: To observe the clinical effects of planting silicone lacrimal drainage tube for punctum lacrimale obstruction diseases.

METHODS: Forty-two punctum lacrimale obstruction patients(72 eyes)were involved and underwent silicone lacrimal drainage tube spherical under local anesthesia, after the surgery they all pointed antibacterial eye drops. All patients were divided into two subgroups; one were over 60 years old, the other all under 60. Irrigation of lacrimal passage was performed once a week for 4 times, then the drainage tube was removed one or three months later.

RESULTS: All the patients were successfully implanted with silicone lacrimal drainage tubes. No secretion was found by lacrimal passages irrigating during 14 months. 59 eyes(82%)were cured completely, 8 eyes(11%)were improved significantly, 5 eyes(7%)were unchanged. And the treatment success was more obvious in younger group than that in elder group.

CONCLUSION: The treatment for punctum lacrimale obstruction diseases by planting silicone lacrimal drainage tube is a perfect way. It is simple, safe, and timesaving, less bleeding without incision, scar and has high successful rate. So this method is worth being spread widely.
