6 Reasons Scleral Lenses Can Manage Your Dry Eye Syndrome

6 Reasons Scleral Lenses Can Manage Your Dry Eye Syndrome 640×350If your eyes are chronically itchy, dry, red or irritated, there’s a good chance you have dry eye syndrome.

Eye drops and artificial tears may provide temporary relief, but they often don’t help individuals with chronic or severe dry eye syndrome. That’s why so many people seek out other treatment options.

One such option is scleral lenses. Although custom-made scleral contact lenses are widely used to correct corneal abnormalities and refractive errors, they can also help patients with intractable dry eye symptoms. Here’s why:

1. Scleral lenses don’t irritate the cornea

Standard contact lenses are typically not an option for people who need vision correction and also have persistent dry eye syndrome. Standard soft lenses sit on the cornea, which can be exceedingly irritating. In contrast, scleral lenses vault over the cornea and sit on the sclera (the white of the eye). The lenses do not come into contact with the corneal surface, reducing discomfort.

2. The scleral lens design ensures constant hydration of the eye

Thanks to sclerals’ unique design, saline solution fills the space between the surface of the cornea and the scleral lens. This provides the eyes with constant hydration. To help lubricate and promote healing of the ocular surface, artificial tears and antibiotics can be administered to the lens’ bowl prior to insertion.

3. Scleral lenses protect the cornea

Dry eye syndrome makes the corneas more susceptible to injury. Due to the mechanical friction of the eyelids on the cornea, even something as basic as rubbing the eye or even blinking can exacerbate any current corneal damage. Sclerals can act as a barrier between a patient’s eyes and their eyelids, as well as the outside environment.

4. Sclerals allow the eye to regain a healthier appearance

Dry eye patients frequently present with eyes that are red or bloodshot. Scleral lenses perform a therapeutic role by providing a shield from the outside world and ensuring a constant supply of hydration. The redness will begin to dissipate once the eyes receive enough moisture.

5. Patients can continue using artificial tears and eye drops while wearing scleral lenses

Patients can continue to moisten their eyes with preservative-free eye drops or artificial tears while wearing scleral lenses. With that said, many patients discover that after they start wearing scleral lenses, they can reduce the frequency of artificial tear use. Some need eye drops only at night, after they have removed their lenses.

6. Scleral lenses can dramatically improve quality of life

Patients with dry eye syndrome can feel worn down by the almost constant discomfort and eye fatigue, not to mention looking tired all the time due to eye redness.

For patients who have suffered from severe dry eye syndrome for months or years, finding relief while enjoying clear and comfortable vision definitely boosts their quality of life.

If you suffer from dry eye syndrome and have been looking for a more effective treatment option, ask Dr. Aisha Cheng, Dr. Brendan Wallace, and Dr. Logan Phenuff about scleral lenses. Call Peninsula Lifetime Eyecare Centre today to schedule your consultation and learn more about these special lenses.

Peninsula Lifetime Eyecare Centre serves patients from Sidney, Brentwood Bay, Saanich, and Victoria, British Columbia and surrounding communities.

Frequently Asked Questions with Dr. Aisha Cheng

Q: What are scleral lenses?

  • A: Scleral contact lenses are gas-permeable lenses that sit on the sclera (the white area of the eye) and form a dome over the cornea. This dome forms a new optical surface over the injured, uneven or dry cornea, allowing for sharper and more comfortable vision.

Q: How long do scleral lenses last?

  • A: These rigid gas permeable contacts are made of high-quality, long-lasting materials and typically last 1-3 years. While scleral lenses are more expensive than standard contact lenses, they’re a worthwhile investment, particularly for those with hard-to-fit eyes, keratoconus, astigmatism or dry eye syndrome.

5 Common Keratoconus Questions, Answered

5 Common Keratoconus Questions, Answered 640If you’re reading this, you or someone you care about may have been recently diagnosed with keratoconus. We’ve compiled a few commonly asked questions about keratoconus to help you understand what it is, what causes it, and how your eye doctor can help.

1. What Is Keratoconus?

Keratoconus is a progressive, non-inflammatory disease that causes the cornea to thin and bulge, resulting in a cone-shaped cornea. Over time, this bulge leads to myopia and irregular astigmatism, and vision becomes progressively distorted. Ongoing treatment is crucial to prevent significant vision loss.

2. What Are the Symptoms of Keratoconus?

Many patients aren’t aware that they have keratoconus, which typically begins during the teenage years.

Symptoms of keratoconus include:

  • Difficulty seeing at night
  • Blurry vision
  • Halos and glare around lights
  • Increased sensitivity to bright light
  • Headaches or eye irritation associated with eye pain
  • Progressively worsening vision that’s not easily corrected

3. What Causes Keratoconus?

While there is no one cause of keratoconus, a paper published in Biomed Research International (2015) identified these risk factors:

  • Genetics – About one in 10 people with keratoconus also has a family member with the condition.
  • Inflammation – Irritation and inflammation from allergies, asthma and other atopic eye diseases can lend to the development of keratoconus.
  • Rubbing your eyes – Intense and frequent eye rubbing is thought to thin out the cornea and can worsen the condition if you already have it.
  • Underlying disorders – Keratoconus has been associated with several conditions, including Down syndrome, Ehlers-Danlos syndrome, Leber congenital amaurosis, Marfan syndrome and Osteogenesis imperfecta.
  • UV light – UV light can cause oxidative stress, which weakens the corneas in predisposed eyes.
  • Weak collagen – In a healthy eye, small protein fibers called collagen help keep the cornea in a dome-like shape and free from bulges. In an eye that suffers from keratoconus, the collagen fibers become weak and therefore can’t maintain the shape of the eye, which causes the cornea to bulge.

4. How Is Keratoconus Treated?

Scleral lenses are the most common and successful treatment for patients with keratoconus. They are specialized rigid, gas permeable contact lenses that have a very wide [diameter] and vault over the entire corneal surface, making them effective and comfortable for people with keratoconus.

5. Is There a Cure for Keratoconus?

Currently, there is no cure for keratoconus. However, in most cases, it can be successfully managed.

For mild to moderate keratoconus, scleral contact lenses are typically the treatment of choice, as they provide clear, comfortable vision.

A relatively non-invasive procedure called corneal cross-linking (CXL) can stabilize and strengthen a thinning and irregularly shaped cornea.

Learning the answers to these common questions is just the first step to preserve your vision. At Peninsula Lifetime Eyecare Centre, we can recommend the best treatment options for your keratoconus, to ensure the highest level of comfort and visual acuity. Call to schedule an appointment to start discussing your keratoconus treatment options.

Frequently Asked Questions with Dr. Aisha Cheng

Q: Can You Go Blind If You Have Keratoconus?

  • A: Keratoconus does not typically cause total blindness. However, as keratoconus progresses it can cause visual impairment including blurred distance vision, distortion, glare, astigmatism, extreme light sensitivity and even vision loss that can be classified as “legal blindness.

Q: Does keratoconus affect both eyes?

  • A: Yes, in approximately 90% of keratoconus cases, the disease will manifest in both eyes. However, the rate of progression and the timing of the onset of the disease is different for each eye.

4 Reasons Why Scleral Lenses Are a Big Deal

happy girl wearing contact lenses 640Scleral contact lenses have been called “life-changing” and “transformative” by patients who wear them.

What makes these contact lenses so revolutionary?

What Are Scleral Lenses?

Scleral lenses are contacts that vault over the entire cornea and rest on the white part of the eye (sclera). Their diameter is much larger than standard lenses, which adds to their comfort and compatibility with hard-to-fit eyes.

Here’s why they’re gaining popularity in the contact lens world and why patients and doctors are calling sclerals a big deal.

1. Sclerals are Ideal for People with Corneal Irregularities or Dry Eyes

There was a time when patients with corneal irregularities or severe dry eye syndrome weren’t able to wear contact lenses at all, due to the discomfort associated with direct corneal contact. Nowadays, patients with keratoconus, other corneal aberrations or dry eye can successfully wear scleral contact lenses and enjoy comfortable and crisp vision.

Scleral lenses are also great for patients with corneal dystrophy, high astigmatism, Sjorgren’s syndrome, corneal trauma and corneal ectasia, or who have undergone cataract surgery.

2. They’re Completely Custom-Made

Each pair of scleral contact lenses is custom-designed to gently and securely rest on your unique eyes. The fitting process for scleral lenses starts with corneal topography, where the optometrist creates a digital map of your eye’s surface. This information is then used to customize your perfectly fitted pair of sclerals.

3. They Offer Optimal Visual Clarity and Comfort

The liquid reservoir that sits between the lens and the eye helps enhance the visual optics of the lens. Moreover, scleral lenses are made of very high-grade materials and don’t place any pressure on the cornea, delivering ultimate all-day comfort. Many patients have reported that they comfortably wear sclerals for up to 14 hours a day, which is longer than the wear time for standard soft contact lenses.

4. They Promote Eye Healing

Scleral contact lenses protect the eye by surrounding it with an oxygen-permeable, liquid-filled chamber. This hydrating environment gives the eye the moisture and oxygen it needs to stay healthy and ward off outside irritants.

This can also explain why scleral lenses promote healing of the eye’s surface, whether after a corneal transplant or when recovering from a chemical burn or other eye injury.

If you or a loved one have been diagnosed with a corneal condition that prevents you from wearing standard lenses, consider scleral lenses. To schedule an appointment or to learn more, call Peninsula Lifetime Eyecare Centre in Sidney today!

Frequently Asked Questions with Dr. Aisha Cheng

Q: #1: How long do a pair of scleral lenses last?

  • A: Scleral lenses can last 1-2 years before requiring replacement. Your optometrist will provide you with instructions on how to wear and care for your lenses to keep them feeling fresh and clean, day in day out.

Q: #2: Are scleral lenses expensive?

  • A: Just like any other customized product, scleral lenses tend to be more expensive than standard soft contact lenses. Although they have a higher price point, most patients who wear them will tell you that their comfort, visual clarity and stability make them worth the cost.
