Punctal Plugs
see also:-
There is a simple non-surgical procedure that provides long-term
relief of Dry Eye that involves the use of permanent, yet removable
plugs called punctal plugs.
There are a number of reasons why punctal plugs have become the
most popular method of treating dry eye. They have a very high rate
of success; and the optometrist can insert them easily and painlessly.
They are also reversible if too much tearing is produced.
The idea behind punctal plugs is simple. Tiny, non-dissolvable plugs
are inserted into your tear drainage ducts (puncta) where they act
as a dam. Therefore, your precious tears have no other way place
go except onto the surface of your eyes.

More than 300,000 dry eye sufferers have been successfully treated,
through punctal and canalicular occlusion.
Here's how they work:
By blocking the tear drains, more natural infection-fighting tears
bathe and soothe the eye, which may eliminate the need for eye drops
altogether. Punctal Plugs can also reduce or eliminate the major
cause of contact lens discomfort.
Eye drops and artificial tears in general temporarily soothe the
symptoms of Dry Eye Syndrome. Sometimes, these solutions can actually
wash away the natural infection-fighting tear film on the eye. Also
most artificial tears contain preservatives which can disrupt the
mucous layer of the tears, that is required to hold your natural
tears in place on the eye.
