DRY EYE TECHNOLOGY
When tears decrease in frequency, Dry Eye is typically the result.
What is Dry Eye Syndrome?
Dry Eye Syndrome, referred to as DES, is a chronic eye condition that occurs when the eyes produce an insufficient amount of tears or when the tears lack the essential oils that lubricate the eye’s surface. (This often results in watery eyes and excessive tearing!). A well-lubricated eye blocks foreign bodies or substances from irritating the eye’s surface.
Dr. Eric Underwood treats patients from all over Sugar Land, Texas who have Dry Eye symptoms, helping them achieve long-lasting relief from Dry Eye Syndrome.
What Causes Dry Eye?
Dry Eye can result from a number of factors, including genetics, the natural aging process, or prescription medications, to name a few.
Hormonal changes are a common cause of Dry Eye. In fact, women who are pregnant, breastfeeding, taking oral contraceptives, or experiencing menopause find that their eyes feel dry and uncomfortable during these times. Women over the age of 50 have a 50% greater chance of developing DES than men of the same age.
Common Symptoms of Dry Eye
Patients with DES experience a number of symptoms that can disrupt their daily activities or cause chronic pain.
The most common signs of DES include the following:
- Feeling as if something is in your eye
- Itchy eyes
- Red eyes
- Watery eyes
Those who suffer from DES often try to alleviate the pain by blinking either less or more often, rubbing their eyes, or by using over-the-counter artificial tears.
Why is blinking important? Blinking is healthy because it naturally moisturizes the eyes and gets rid of tiny particles that may enter the eye. Less blinking can increase dryness, itching, or redness, making DES symptoms even more acute.
Rubbing your eyes, especially when they’re already irritated, can intensify your symptoms. This is because the added pressure can make the pain worse. If your hands aren’t 100% clean, you can unintentionally spread germs or bacteria into your eyes when you rub them. Rubbing the eyes can also cause tiny blood vessels to break, increasing the redness of your eyes.
Artificial tears provide some temporary relief by lubricating the eyes with a medicated solution. These can be quite effective at alleviating soreness and itchiness, however, excessive use isn’t recommended. Many brands include preservatives, which aren’t good for your health in the long-term. Other preservative-free brands can, over time, fail to relieve the basic Dry Eye symptoms. Patients may find that having to continuously purchase artificial tears can become costly, and consistently using them throughout the day disrupts their daily activities.
Dry Eye Technology
Advancements in medical technology and scientific breakthroughs have made treatment for Dry Eye easier, with quicker results, and longer-lasting benefits. Three of the up-and-coming technologies for DES treatment are InflammaDry, LipiFlow, and TearLab.
Texas State Optical Riverstone has some of the most cutting-edge and advanced technologies to quickly and effectively test for Dry Eye Syndrome. Let Dr. Eric Underwood and the talented, experienced staff help get you started on the path to real long-term relief from Dry Eye.
Our tears contain a natural protein enzyme called matrix metalloproteinase-9, or MMP-9. Patients with Dry Eye usually have elevated levels of this protein. The InflammaDry system measures MMP-9 levels by analyzing the tears taken from inside the lower eyelid. The entire process is fast and results are received in about 10 minutes. The disposable test is performed in the office, making it a top choice for doctors and DES patients.
Meibomian glands are located by the eyelashes, towards the edge of the eyelid. These glands secrete oils, which lubricate the eye and keep your tears moist. When the glands become blocked, Dry Eye occurs.
The LipiFlow system takes detailed images of the tear film in the eye, so that the doctor can determine if you have MGD. Then a combination of gentle heat and light pressure are applied on both the inside and outside of the eyelid, removing the blockage and stimulating your eye’s natural moisture. The procedure takes around 12 minutes to administer and is done in the doctor’s office.
The TearLab device measures concentration levels in human tears. This helps diagnose DES by noting any levels of tear concentration that are elevated, which can be a sign of Dry Eye.
TearLab consists of a 3-in-1 device: the test card, test pen, and countertop unit. The test card is a single-use microchip that collects a tiny sample of tear fluid in under 30 seconds. It sits inside the test pen, which analyzes and sends the data t the reader, which is in the unit. The unit rests on a flat surface and displays the test results in seconds.
