Dry eye can be improved with surgery, often with embolization of the lacrimal dots. The lacrimal dots are the openings of the tear ducts, through which the tears are secreted by the tear glands and enter the tear ducts and drain into the nasal cavity. If the tear dots are embolized, the residence time of the tears on the surface of the eye will increase, which can theoretically improve the symptoms of dry eye, and this type of surgery can be very helpful in treating dry eye. For patients with dry eye, the first thing is to first carry out eye drop replacement therapy, such as sodium glassate or polyvinyl alcohol type of artificial tear drops, if the use of artificial tear drops still does not work, you can also consider autologous serum or eye cream or gel to maintain the environment of the eye surface. If none of these methods work, surgical treatment should be considered. However, tear plugs are biodegradable materials that often have little effect on the body, and the surgical results are good enough to consider.
