Description

Technical Field

[0001] The utility model relates to the technical field of lacrimal duct plugs, in particular to a novel lacrimal duct plug. Background Art

[0002] Tear duct embolization is one of the most commonly used methods to treat dry eyes. Tear duct embolization is implanted by partially blocking the tear drainage duct to increase the natural tears on the surface of the eye that lubricate it. This treatment can effectively relieve dry eye symptoms in the long term. For many people, tear duct embolization can effectively reduce or even eliminate the use of artificial tears.

[0003] Classification: Punctal plugs are divided into two types: degradable and permanent. Degradable collagen punctal plugs will eventually dissolve, while permanent ones can only be removed manually.

[0004] The two types of tear plugs currently available can solve the dry eye symptoms of some patients. However, some patients may experience excessive tear retention on the ocular surface after the tear plug is implanted, resulting in epiphora symptoms. Once the tear plug is removed, dry eyes may occur again due to insufficient tear secretion.

[0005] Based on this, a new type of tear duct plug is designed, which can slow down the loss of tears and retain some tears to achieve a sustained release effect, thereby maintaining a relatively normal tear volume on the ocular surface. Utility Model Content
