Background
Lacrimal passage obstruction is a common and frequently encountered disease in ophthalmology, and is a disease which usually occurs in punctum, lacrimal canaliculus, lacrimal duct and nasolacrimal duct, and has the main symptoms of epiphora caused by obstruction due to trauma and inflammation. Lacrimal duct obstruction is generally divided into upper lacrimal duct (punctum, canaliculus, common lacrimal duct) obstruction and lower lacrimal duct (lacrimal sac, nasolacrimal duct) obstruction. The obstruction of the lower lacrimal passage can be solved by probing the lacrimal passage, placing a supporting tube in the lacrimal passage for a short time, and performing a nasal cavity lacrimal sac fenestration or anastomosis operation. However, the upper lacrimal passage has small diameter, and the lacrimal passage is blocked or broken especially after the injury (mechanical or chemical) of the lacrimal passage, and the conventional solution can not solve the problem of the lacrimation. Artificial lacrimal passages are the last approach to the solution. However, in the prior art, the artificial lacrimal duct is mostly made of silica gel, glass and metal.
