Punctal Occluders (plugs) are indicated for the treatment of “dry eye” syndrome. “Dry eye being a condition where there is insufficient lubrication in the eye and the conjunctive becomes much less moist than normal. This produces pain and discomfort in the eyes. This may occur in any condition that causes scars of the cornea, such as erythema multiforme, trachoma, or corneal burns;” Other patients that may benefit are: cataract patients, patients with arthritis, patients medicated for hypertension, contact wearers of any age, seasonal allergy sufferers, patients who live in dry climates, or spend extended periods in air conditioning, and any others who suffer from dry eye irritation. Treatment is to stop tear outflow via a specific punctum to enhance tear contact time in certain dry eye conditions. It is also reasonable that eye drops of many kinds would be more effective if retained on the surface of the eye, rather than drained into the sinus.
