方法：确诊泪道阻塞(不含慢性泪囊炎)患者102例134眼，随机分为两组，一组60眼行激光泪道成形联合硅油填充，另一组74眼行激光泪道成形联合眼膏填充，对比治疗3mo后两组疗效及冲洗和探通的次数，评估方法优劣。

结果：术后3mo，硅油组有效率87%，眼膏组有效率84%，两组比较差异无统计学意义(P>0.05)； 术后3mo冲洗次数硅油组7.20±1.22次、眼膏组7.96±1.79次，探通次数硅油组0.62±0.87次、眼膏组1.43±1.48次； 两组冲洗及探通次数比较差异均有统计学意义(均P<0.05)。

结论：作为泪道激光术后填充物，硅油不仅具有与眼膏接近的效果，而且可明显减少术后复诊冲洗及探通的次数。

METHODS: Totally, 134 eyes of 102 cases who were diagnosed as lacrimal duct obstruction(except chronic dacryocystitis)were divided into two groups. Sixty eyes were performed laser plastic operation and silicone oil filling. Seventy-four eyes were adopted laser plastic operation with cloth enzyme dexamethasone eye ointment filling. All patients were followed up for 3～15mo. The clinical effect and the number of irrigation of two groups were compared 3mo after treatment, and to assess the merits of the method.

RESULTS: The efficiency of the silicone oil group was 87% and that of the eye ointment group was 84%. There was no statistically significant difference(P>0.05). The number of lacrimal duct flushing of the silicone oil group was 7.20±1.22 times among postoperative 3mo, and that of the eye ointment group was 7.96±1.79 times. The number of lacrimal duct exploration through of the silicone oil group was 0.62±0.87 times, that of the eye ointment group was 1.43±1.48 times. There was statistically significant differences compared between the two groups(both P<0.05).

CONCLUSION: The effect of laser plastic operation and silicone oil filling treating obstructive diseases of lacrimal duct is similar to laser plastic operation with cloth enzyme dexamethasone eye ointment, but the postoperative care of the former is more simple. Patients can significantly reduce the frequency of lacrimal duct flushing and lacrimal duct exploration through.
