磷酸钾钛激光疏通及人工鼻泪管植入效果观察

目的观察磷酸钾钛（KTP）激光疏通联合人工鼻泪管植入术治疗鼻泪管阻塞合并慢性泪囊炎的治疗效果。方法鼻泪管阻塞合并慢性泪囊炎46例（46眼），采用KTP激光疏通阻塞的鼻泪管，通畅后逆行植入人工鼻泪管。随访3年。结果46例（46眼）中，半年内46眼泪道冲洗通畅，成功率100％；术后1年，治愈率91％，术后2年，治愈率87％，术后3年，治愈率80％。结论KTP激光联合人工鼻泪管植入术治疗鼻泪管阻塞合并慢性泪囊炎无瘢痕，不改变鼻泪管生理解剖结构，效果尚好。

Kalium titanyl phosphate laser dredging combined with artificial nasolacrimal duct intubation for na-solacrimal duct obstruction

Objective To evaluate the effect of Kalium titanyl phosphate （KTP） laser dredging combined with artificial nasolaerimal duct intubation for uasolacrimal duct obstruction. Methods 46 eyes of 46 patients with nasolacrimal duct obstruction were screened. They were also suffered with chronic dacryo- cystitis and were treated with KTP laser dredging combined with nasolacrimal duct intubation. All of them were followed up for 3 years. Results All of the 46 eyes of 46 patients were implanted with artificial naso-lacrimal duct. They were operated successfully. The success rate was 100% after half an year. The curative rate was 91% in 1 year, 87% in 2 years and 80% in 3 years after the operation. Conclusion KTP laser dredging combined with artificial nasolacrimal duct for nasolacrimal duct obstruction is a simple, safe and ef- fective treatment method for nasolacrimal duct obstruction, without skin scars or changing of the physical a- natomy.
