Dry eye is a medical condition where the individual fails to have enough quality tears to nourish and lubricate the eye. Tears are critical to the health of the eye and necessary for clear vision. As the individual blinks, tears are dispersed over the cornea to:

  • Wash away pollutants
  • Minimize the risk of eye infection
  • Provide lubrication
  • Keep the eye surface clear and smooth

Any extra tears in the eye are channeled into tiny drainage ducts, called the punctum, in the corner of the eyelid, which then drain to the back of the nose. Dry eye can also occur when drainage and tear production is out of balance. 

At Keeler, our HD Analyzer Optical Quality Analysis System (OQAS) is a powerful tool used by ophthalmologists and eye care professionals to diagnose and treat dry eye. Let's take a closer look at dry eye and how the HD Analyzer OQAS can help improve patient outcomes.

Bringing Dry Eye into Clearer Focus

People who suffer from dry eyes either have tears of poor quality or do not produce sufficient tears. 

Poor Quality Tears

Tears are composed of three layers: oil, water, and mucus. Each component has a specific job to protect and nourish the front of the eye. The mucus layer is tasked with evenly spreading tears over the eye's surface, while the smooth oil layer works toward preventing the water layer from evaporating. 

If tears fail to evenly spread over the cornea (due to deficiencies with the layers or quick evaporation), the individual will most likely experience dry eye symptoms. 

Keratoconjunctivitis Sicca 

Keratoconjunctivitis Sicca (KCS) is the most common type of dry eye. KCS occurs when the individual has an inadequate water layer. 

Insufficient Tears

The tears in the eye are created by multiple glands around and in the eyelids. As an individual ages, tear production tends to diminish due to medication side effects or because of different medical conditions. 

Dry climates, wind, and other environmental factors can also reduce tear volume and increase the evaporation of tears. Anytime the tears evaporate too quickly or when normal tear production decreases, dry eye symptoms can start to develop. 

What Are the Symptoms of Dry Eye?  

Dry eye symptoms and signs may affect one or both of the individual's eyes. A few of the most common symptoms of dry eye include:

  • Blurred vision, particularly when reading
  • Sensitivity to light
  • Burning and stinging sensation of the eye
  • Strings of mucus around or on the eye
  • Difficulty with driving at night
  • Eye fatigue
  • A gritty or scratchy sensation as if something were in the eye
  • Pain when wearing contact lenses
  • Irritated or red eyes, especially when near cigarette smoke or wind
  • Overproduction of tears or watery eyes

Risk Factors and Causes of Dry Eye

Certain factors can increase the likelihood of developing dry eye. Some of the risk factors include:

  • Age. People over 50 are more likely to experience dry eye due to diminished tear production because of age.
  • Sex. Dry eye and a lack of tears are more common among women.
  • Hormonal Changes. Women who are experiencing hormonal changes are even more at risk to develop dry eye. Hormonal events such as pregnancy, going through menopause, or using birth control can all increase the risk of developing dry eye.
  • Diet. Individuals with a diet low in Omega-3 Fatty Acids (vegetable oils, walnuts, and fish) or low in Vitamin A (broccoli, carrots, and liver) are found to be more susceptible to dry eye.

Other common causes of dry eye include:

  • Engaging in activities that reduce blinking, such as staring at a computer screen, reading, etc.
  • Certain diseases like thyroid disease, rheumatoid arthritis, and lupus
  • Being in dry climates, smoke, or wind
  • Ectropion and entropion
  • Certain medications like diuretics, anxiety medication, antidepressants, sleeping pills, antihistamines, beta-blockers, and heartburn medicines.

Confidently Diagnose Dry Eye with the Keeler HD Analyzer OQAS

HD Analyzer in Use

With the HD Analyzer in your clinic, you can grow your practice by confidently and objectively diagnosing poor tear film in asymptomatic patients. It is an extremely fast, non-invasive, and objective way to measure the fluctuation in vision caused by dry eye disease. When you measure vision breakup time, you'll create a clear path toward increasing patient satisfaction, improving outcomes, and efficiently growing your practice revenue. 

How Does the Keeler HD Analyzer OQAS Work?  

Seeing Dry Eye Differently

The Keeler HD Analyzer’s diagnostic software quantifies vision breakup time, which is the amount of time a patient takes to lose one line of vision on the snellen chart. You don't have to wait for drops, long protocols, or strips; the HD Analyzer OQAS completes the analysis in less than one minute. 

In addition, the device analyzes tear film without disturbing it in its natural state. This leads to more precise and accurate results that reflect the real-world environment, which means patients enjoy greater comfort. 

Remove Variability — Achieve Objectivity with the HD Analyzer Optical Quality Analysis System

The HD Analyzer OQAS works to completely remove variability within patient reporting. You'll also establish a baseline that empowers you to track how effective the dry eye treatment has been. It delivers an easy-to-read report you can use to best educate your patients on not only their current status, but also any progression on their treatment program. 

Simply put, your patients will be able to clearly see how their overall vision is impacted by the poor tear film.
