Get the Best Treatment for Lacrimal Duct Obstruction Surgery in India
Tears drain through small openings in the corners of the lower and upper eyelids called puncta and enter the nose through the nasolacrimal duct. An obstruction in the duct blocks the normal flow of tears and causes a backflow in the eye. Blockage of the drainage system causes tears to well up on the surface of the eyes and overflow on the eyelashes, eyelids, and down the cheek.
In such a situation, the eyelids can become red and swollen, and sometimes may even stick together. The severity of such signs may vary under different conditions such as respiratory illness or outdoor exposure to wind and dust. The treatment procedure depends on the reasons for blockage of tear ducts. The reasons may be a tumor or infection and the treatment differs accordingly. It requires more than one approach to receive proper treatment.
In order to receive the best treatment for nasolacrimal duct obstruction, one should be well-informed about the surgical procedure, expected results and complications. DCR (Dacryocystorhinostomy) is the surgical procedure used to treat the duct obstruction. This surgical procedure eliminates the fluid and mucus retention in the lacrimal sac. It releases the tear drainage and relieves the epiphora. The DCR procedure involves the removal of the bone adjacent to the lacrimal sac and incorporating the lacrimal sac with the lateral nasal mucosa to bypass the nasolacrimal duct obstruction. It allows tears to directly drain into the nasal cavity from the canaliculi through a low-resistance pathway.
If stable, the patient is discharged post-surgery and advised rest for a week. The patient is instructed not to do any heavy lifting, exercise or undertake any strenuous activity that can induce bleeding. Hot drinks and food are also prohibited for the first 24 hours to reduce the risk of epistaxis caused by the heat induced nasal vasodilation. Ice should be placed on the site of incision for at least 48 hours while awake to minimize swelling and bruising. The patient is told to elevate the head always at a 45-degree angle and not blow air from the nose to reduce the risk of hemorrhage. The silicone tube is removed 4 to 8 weeks after the surgery.
