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]
When eyes are untaped during general anaesthesia, the incidence of ocular injury has been reported to be as high as 44%. [1] [2] If tape is used to hold the eyes closed, ocular injury occurs during 0.1-0.5% of general anaesthetics, and is usually corneal in nature. [3] [4]
Artificial tears work by adding similar lubricating elements that natural tears contain. [17] This helps thicken and stabilize the pre-corneal tear film, prolonging tear film breakup time, and allowing for tears to properly protect the surface of the eyes. [17] Most artificial tears do not require a prescription and can be used as often as needed.
With the eye generally profusely watering, the type of tears being produced have little adhesive property. Water or saline eye drops tend therefore to be ineffective. Rather a 'better quality' of tear is required with higher 'wetting ability' (i.e. greater amount of glycoproteins) and so artificial tears (e.g. viscotears) are applied frequently.

[2] This can be due to ocular irritation and inflammation (including trichiasis and entropion) or an obstructed tear outflow tract, which is divided according to its anatomical location (i.e., ectropion, punctal, canalicular or nasolacrimal duct obstruction).
