Techinque Improvement of ringing intubation for lacrimal canaliculi occlusion

Abstract:

AIM: To ameliorate the techniques and instruments forlacrimal duct obstruction in order to learn easily and achieve better surgical effects.

METHODS:Group A: 90 eyes with lacrimal duct obstruction were treated with the ameliorated annular silicone stent intubation; Group B: 80 eyes were treated with the classical annular stent intubation. Follow up in 2 years after operation, comparing the rate of cure and efficiency between the two groups.

RESULTS: After a two-year follow-up, in group A, 80(89%)eyes were cured, 7 eyes(7.8%)turned better and 3 eyes failed to respond, the total effective rate was 97%; in group B, 60(75%)eyes were cured, 9(11%)turned better and 11 failed to respond, the total effective rate was 86%. Differences in cure rate(χ²=5.62, P<0.05)and total effective rate(χ²=4.78, P<0.05)between two groups had statistical significance.

CONCLUSION: The ameliorated means is simple and effective in treatment oflacrimal canaliculi occlusion, it is worth of spreading.
