## Indications for use
The OASIS® Medical Silicone Punctal Plug is intended for use in patients experiencing dry eye symptoms such as redness, burning, reflex tearing, itching or foreign body sensations which can be relieved by blockage of the punctum Silicone Punctal Plug may be used in the treatment of dry eye syndrome and the dry eye components of various ocular surface diseases such as corneal ulcers, conjunctivitis, pyterygium, blepharitis, keratitis, red lid margins, recurrent chalazions, recurrent corneal erosion, filamentry keratitis and other external eye diseases. 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. 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.
