Dry Eye Clinic

Dry Eye

Dry eye is a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film. It is accompanied by ocular symptoms, in which tear film instability and hyperosmolarity, ocular surface inflammation and damage, and neurosensory abnormalities play etiological roles. People suffering with dry eye disease usually have more than one reason for having it, and have more than one component of it.

Causes of Dry Eye  

Life style: Staring at computer screens, televisions or electronic readers for long periods of time, exposure to air conditioning, wind, smoke, and dry climates.

Age: Dry eye disease of ten gets worse as we age

Gender: Women are more likely to develop dry eyes

Other factors: Long term use of contact lenses, refractive eye surgery such as LASIK, PRK, cataract surgery, some medications such as antihistamine, glaucoma eye drop, medical conditions such as rheumatoid arthritis, sjogren’s, lupus, diabetes, thyroid problems and inflammation of the eyelids.

In a healthy eye, tears are responsible for the perfectly smooth ocular surface which allows clear vision. Tears also clean and lubricate the eye. Every time we blink, a fresh layer of tears, known as the tear film, spreads over the eye. The tear film is important for keeping the eye moist and comfortable. With dry eye disease, the eye may stop producing enough tears or tears evaporate too quickly.

Dry eye is a chronic and progressive disease that requires consistent and complete treatment with regular follow ups for monitoring and control. Approximately 34 million people (1 in 10) are affected with dry eye disease in the United states. Our goal at Thomas Eye Center is to identify patients with Dry Eye Disease, or at risk of Dry Eye Disease, and treat them well before these anatomical changes are seen and well before there are any symptoms.

Dry Eye affects quality of life. People suffering with dry eye disease may experience irritated, gritty, scratchy, burning eyes, excess watering, and blurred vision. The level of discomfort is increased if you wear contact lenses or live in a dry climate. Paying attention to dry eye symptoms is important. If left untreated it may become so severe that it interferes with work and normal life activities.
