Dry Eye Disease
Symptoms, Causes, and Modern Treatment
Dry eye disease is one of the most common conditions treated by eye specialists. Millions of people experience symptoms such as burning, irritation, fluctuating vision, or excessive tearing. Although these symptoms may seem minor at first, untreated dry eye can significantly affect visual comfort, contact lens tolerance, and overall eye health.
At Laser & Corneal Surgery Associates, we specialize in diagnosing and treating dry eye disease using advanced diagnostic technology and personalized treatment strategies designed to restore comfort and improve the health of the ocular surface.
What Is Dry Eye Disease?
Dry eye disease occurs when the eyes do not produce enough tears or when tears evaporate too quickly. Tears play a vital role in maintaining a healthy ocular surface. They lubricate the eyes, protect against infection, and provide a smooth optical surface necessary for clear vision.
A healthy tear film contains three important layers:
Oil Layer
Produced by the meibomian glands in the eyelids, this layer prevents tears from evaporating too quickly.
Water Layer
Produced by the lacrimal glands, this provides hydration and nutrients to the surface of the eye.
Mucus Layer
Helps the tears spread evenly across the cornea.
If any component of this tear film becomes unstable, the eyes may develop symptoms of dryness and irritation.
Symptoms of Dry Eye
Dry eye symptoms can vary widely and may fluctuate throughout the day. Common symptoms include:
Why Dry Eye Can Cause Excess Tearing
Many patients are surprised to learn that watery eyes are often a sign of dry eye disease.
When the surface of the eye becomes irritated due to inadequate lubrication, the lacrimal glands may produce a surge of reflex tears. These tears lack the oil layer necessary to remain on the eye’s surface, so they overflow and run down the cheeks.
Common Causes of Dry Eye
Dry eye disease may occur for many reasons, including changes in tear production, eyelid dysfunction, or environmental factors.
Contact Lenses and Dry Eye
Contact lens wear can contribute to dry eye symptoms through several mechanisms.
Studies have shown that contact lens wearers may experience a 20–40% decrease in blink rate, particularly during computer use. Blinking functions like a windshield wiper, spreading the tear film evenly across the surface of the eye.
Contact lenses may also reduce corneal sensitivity and alter the natural tear film, increasing evaporation and dryness.
For many patients, treating the underlying dry eye condition can significantly improve contact lens comfort.
How Dry Eye Is Diagnosed
Accurate diagnosis is essential for effective treatment. A comprehensive dry eye evaluation may include tests to measure:
Advanced imaging technologies may also be used to evaluate the structure of the meibomian glands and determine whether gland dysfunction is contributing to dry eye symptoms.
Treatment for Dry Eye Disease
Dry eye treatment is tailored to the underlying cause of the condition. In many cases, a combination of therapies is recommended.
Common treatments include:
When to See an Eye Specialist
Persistent dry eye symptoms should be evaluated by an eye doctor. Untreated dry eye may lead to:
Early diagnosis and treatment can significantly improve comfort and protect long-term eye health.
Advanced Dry Eye Treatment
Modern dry eye therapy focuses on identifying and treating the underlying cause of tear film instability.
At Laser & Corneal Surgery Associates, we use advanced diagnostic technology to determine the type and severity of dry eye.
Comprehensive Dry Eye Evaluation
Your evaluation may include:
These tests help determine whether your dry eye is caused by reduced tear production, excessive tear evaporation, or eyelid inflammation.
