Dry Eye Treatment

Dry eye syndrome (DES or dry eye) is a chronic lack of sufficient lubrication and moisture on the surface of the eye. Its consequences range from minor irritation to the inability to wear contact lenses and an increased risk of corneal inflammation and eye infections.

Signs and Symptoms of Dry Eye

These symptoms alone may be enough for your eye doctor to diagnose dry eye syndrome. Sometimes, he or she may want to measure the amount of tears in your eyes. A thin strip of filter paper placed at the edge of the eye, called a Schirmer test, is one way of measuring this.

Some people with dry eyes also experience a "foreign body sensation” – the feeling that something is in the eye. And it may seem odd, but sometimes dry eye syndrome can cause watery eyes, because the excessive dryness works to overstimulate production of the watery component of your eye's tears.

What Causes Dry Eyes?

In dry eye syndrome, the tear glands that moisturize the eye don't produce enough tears, or the tears have a chemical composition that causes them to evaporate too quickly.

Dry eye syndrome has several causes. It occurs:

  • As a part of the natural aging process, especially among women over age 40.
  • As a side effect of many medications, such as antihistamines, antidepressants, certain blood pressure medicines, Parkinson's medications and birth control pills.
  • After extended exposure to computers and other electronic devices (this is often referred to as, "computer eyestrain.")
  • Because you live in a dry, dusty or windy climate with low humidity.

Dry eyes are also associated with certain systemic diseases such as lupus, rheumatoid arthritis, rosacea or Sjogren's Syndrome (a triad of dry eyes, dry mouth, and rheumatoid arthritis or lupus).

Long-term contact lens wear, incomplete closure of the eyelids, eyelid disease and a deficiency of the tear-producing glands are other causes.

Dry eye syndrome is more common in women, possibly due to hormone fluctuations. Recent research suggests that smoking, too, can increase your risk of dry eye syndrome. Dry eye has also been associated with incomplete lid closure following blepharoplasty – a popular cosmetic surgery to eliminate droopy eyelids.

Treatment for Dry Eye

Dry eye syndrome is an ongoing condition that treatments may be unable to cure. But the symptoms of dry eye – including dryness, scratchiness and burning – can usually be successfully managed.

Your eyecare practitioner may recommend artificial tears, which are lubricating eye drops that may alleviate the dry, scratchy feeling and foreign body sensation of dry eye. Prescription eye drops for dry eye go one step further: they help increase your tear production. In some cases, your doctor may also prescribe a steroid for more immediate short-term relief.

Another option for dry eye treatment involves a tiny insert filled with a lubricating ingredient. The insert is placed just inside the lower eyelid, where it continuously releases lubrication throughout the day.

If you wear contact lenses, be aware that many artificial tears cannot be used during contact lens wear. You may need to remove your lenses before using the drops. Wait 15 minutes or longer (check the label) before reinserting them. For mild dry eye, contact lens rewetting drops may be sufficient to make your eyes feel better, but the effect is usually only temporary. Switching to another lens brand could also help.

Check the label, but better yet, check with your doctor before buying any over-the-counter eye drops. Your eye doctor will know which formulas are effective and long-lasting and which are not, as well as which eye drops will work with your contact lenses.

To reduce the effects of sun, wind and dust on dry eyes, wear sunglasses when outdoors. Wraparound styles offer the best protection.

Indoors, an air cleaner can filter out dust and other particles from the air, while a humidifier adds moisture to air that's too dry because of air conditioning or heating.

For more significant cases of dry eye, your eye doctor may recommend punctal plugs. These tiny devices are inserted in ducts in your lids to slow the drainage of tears away from your eyes, thereby keeping your eyes more moist.

If your dry eye is caused by meibomian gland dysfunction (MGD), your doctor may recommend warm compresses and suggest an in-office procedure to clear the blocked glands and restore normal function.

Doctors sometimes also recommend special nutritional supplements containing certain essential fatty acids to decrease dry eye symptoms. Drinking more water may also offer some relief.

If medications are the cause of dry eyes, discontinuing the drug generally resolves the problem. But in this case, the benefits of the drug must be weighed against the side effect of dry eyes. Sometimes switching to a different type of medication alleviates the dry eye symptoms while keeping the needed treatment. In any case, never switch or discontinue your medications without consulting with your doctor first.

Treating any underlying eyelid disease, such as blepharitis, helps as well. This may call for antibiotic or steroid drops, plus frequent eyelid scrubs with an antibacterial shampoo.

If you are considering LASIK, be aware that dry eyes may disqualify you for the surgery, at least until your dry eye condition is successfully treated. Dry eyes increase your risk for poor healing after LASIK, so most surgeons will want to treat the dry eyes first, to ensure a good LASIK outcome. This goes for other types of vision correction surgery, as well.

With the Keratograph® 5M, you can show your patients images they have never seen before. Gain patient trust by providing professional consultation during examinations and follow-ups.

Dry Eyes FAQ

Hey doc, my eyes water all the time. People ask me why I am crying. What causes that?

Well, the answer is counter-intuitive to what you might think.  Typically, watery eyes are a symptom of dry eye disease.

Dry eyes? I just told you they water all the time. What is dry eye disease?

Dry eye disease(DED) is a progressive and chronic disease that is multifactorial.  Hormones, or lack there of, environment, and medications are a few factors that lead to DED. In DED, the tear film that hydrates the eye is disrupted because of a decrease in the amount of tears made, the oil glands are not working properly, or there is inflammation present decreasing tear production.

Can I just use some Visine and make it stop tearing?

No! Visine and other drops that “get the red out” are not lubricating tears.  They may get the red out temporarily, but the redness will return and then some.  Redness is an indicator that something is wrong and should not be ignored.  

Alright, how can I stop my eyes from watering all the time?

The answer is not an easy one.  Dry eye disease can have many underlying causes that need to be addressed.  An eye doctor can look at the the eyes and assess the water, oil, and inflammation present in the eye to target therapy specifically for each person. 

DED in a 78 year old female looks very different from that in a 15 year old male and the treatment may be different for each.  Most people suffering from DED can benefit from good lid hygiene, proper blinking, good hydration and nutrition.  Over the counter artificial tears like Refresh, Systane or Blink can provide short term lubrication and mild relief of symptoms. 

High quality triglyceride fish oil like PRN DryEye Omega or Nordic Naturals are two I recommend to help decrease inflammation in the eye and increase the oil quality and production to help lubricate the eye naturally. Finally, there are prescription medications that can be given to help decrease ocular inflammation and increase tear production to relieve symptoms of DED.

What are some of the other symptoms of dry eye disease?

While eye watering is one of the most common symptoms, DED may cause burning, redness, itching, blurred vision, light sensitivity, or a feeling like a piece of sand or grit is under the lid.
