Clinical treatment of dry eye is mainly through removing the cause of the disease, topical medication, wearing therapeutic lenses, laser, surgery and other methods. 1. Remove the causes of the disease: if the dry eye is caused by medication, the medication should be stopped in time; if the dry eye is caused by systemic disease, the patient should consult the relevant department for systemic treatment. Correct bad eye habits, such as avoiding staying in an air-conditioned environment for a long time or avoiding the use of electronic products for a long time. 2. Topical medication for eyes: artificial tears or autologous serum, such as sodium vitrate eye drops, can be used topically; if accompanied by local inflammation, antibiotic eye drops, such as levofloxacin eye drops, can be used at the same time. 3. Wear therapeutic lenses: Wear wet room lenses or therapeutic corneal contact lenses to keep the surface of the eye moist. 4. Laser, surgery: Closure of tear ducts or lacrimal puncta by laser cauterization or surgical implantation to reduce tear absorption. It is recommended that dry eye patients go to the hospital for timely examination and treatment as prescribed by the doctor.
