31 results about "Lacrimal gland" patented technology

In human physiology, the lacrimal glands are paired, almond-shaped exocrine glands, one for each eye, that secrete the aqueous layer of the tear film. They are situated in the upper lateral region of each orbit, in the lacrimal fossa of the orbit formed by the frontal bone. Inflammation of the lacrimal glands is called dacryoadenitis. The lacrimal gland produces tears which then flow into canals that connect to the lacrimal sac. From that sac, the tears drain through the lacrimal duct into the nose.

Contact lens for increasing tear production

Described here are devices, systems, and methods for increasing tear production by stimulating the cornea, conjunctiva, and / or subconjunctiva. In some variations, the devices may be in the form of a contact lens. The contact lens may comprise a lens body and a stimulator chip, where the stimulator chip is embedded in the lens body. An external power source wirelessly transmits energy to the stimulator chip, where the stimulator chip may convert the energy to an electric waveform to stimulate the cornea, conjunctiva, and / or subconjunctiva. Stimulation may activate the lacrimal reflex to increase tear production. The devices and systems for increasing tear production may be used in methods of treating dry eye, reducing the symptoms of tired eye, increasing comfort for contact lens wearers, and extending the number of years a contact lens user can wear contacts. Also described are methods of manufacturing a contact lens.

Lacrimal filler

A biomaterial mass is inserted through a punctum into a canaliculus in the lacrimal outflow system with a syringe. The mass has an outer cross section that is less than the inner cross section of the canaliculus. The mass absorbs liquid to swell to form a lacrimal filler or sealing mechanism. The lacrimal filler has an external cross section that conforms to the internal cross section of the canaliculus and a soft outer surface relative to the surrounding tissues to prevent erosion of the canaliculus lining. The lacrimal filler forms an occlusion that prevents the outflow of liquid through the lacrimal outflow system to retain tears within the eye to maintain eye lubrication and wetness. The mass and syringe are provided in kit with a rubber stopper and, optionally, a punctal dilator, an injecting catheter, and an enzyme for dissolving or degrading the lacrimal filler at a later time.
