A punctal plug, also known as tear duct plug or lacrimal plug, is a small medical device that is inserted into the tear duct (puncta) of an eye to block the duct. This prevents the drainage of liquid from the eye. They are used to treat dry eye. Artificial tears are usually still required after punctal plug insertion. [1]
Punctoplasty is a surgical procedure to restore proper drainage of tears [1] when the lacrimal punctum (puncta lacrimalia) becomes blocked in one or both eyes.. If a blockage is present in the puncta, doctors may suggest a procedure called punctoplasty, performed to widen the drain opening.
In one study, about half of the transplant patients with lattice dystrophy had a recurrence of the disease between two and 26 years after the operation. Of these, 15 percent required a second corneal transplant. Early lattice and recurrent lattice arising in the donor cornea responds well to treatment with the excimer laser.
Persons with dry eye conditions can be fitted with punctal plugs that seal the ducts to limit the amount of fluid drainage and retain moisture. During an ear infection, excess mucus may drain through the nasolacrimal duct in the opposite way tears drain. [citation needed] In humans, the tear ducts in males tend to be larger than the ones in ...

A punctal plug may be inserted into the tear duct by an optometrist or ophthalmologist, decreasing the removal of natural tears from the affected eye. [8] The use of contact lenses may help prevent the abrasion during blinking lifting off the surface layer and uses thin lenses that are gas permeable to minimise reduced oxygenation.
The first phase, the prodrome phase, can begin as early as 24 to 48 hours before the pain hits, Broner says. For some, however, it's just 30 minutes to 5 minutes, she adds.
