If the lacrimal glands have ceased to function, then what kind of operation can compensate

If the lacrimal glands have ceased to function, then what kind of operation can compensate for the absence of tear fluid?

If the lacrimal glands have stopped functioning, then this has bad consequences. A person not only will not be able to cry. The lacrimal glands have a much greater function. They moisturize the eye and protect it from drying out. When a foreign particle enters the eye, tears wash it away. But if the lacrimal glands do not function, then you have to periodically drip your eyes with a special solution, which has the same composition as a tear. You also need to take special medications or do procedures to restore the glands.
