Punctal plugs are thought to be "relatively safe", however, their use may result in epiphora (watery eyes), and more rarely, serious infection and swelling of the tear sac where the tears drain. [60] They are reserved for people with moderate or severe dry eye when other medical treatment has not been adequate.
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.
Some patients with more severe problems use goggles to increase local humidity or have punctal plugs inserted to help retain tears on the ocular surface for a longer time. [78] Additionally, cyclosporine (Restasis) is available by prescription to treat chronic dry eye by suppressing the inflammation that disrupts tear secretion.
Individuals with Medicare Part D who use Restasis may be eligible for myAbbVie Assist and other prescription cost support. Learn more here.
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]
Lifitegrast, sold under the brand name Xiidra (/ ˈ z aɪ d r ə / [2]), is a medication for the treatment of signs and symptoms of dry eye, a syndrome called keratoconjunctivitis sicca. Lifitegrast reduces inflammation by inhibiting inflammatory cell binding. [ 3 ]
