Everything You Need To Know About Keratoconus

Everything You Need To Know About Keratoconus 640×350If you’ve been diagnosed with keratoconus, our Murrysville eye doctors understand your challenge and are here to help you see clearly and comfortably.

Below are some of the most commonly asked questions to help you gain a better understanding of what keratoconus is and how it can be treated.

What is Keratoconus?

Keratoconus affects about 1 in every 2,000 people. This progressive eye disease impacts the shape of the cornea, weakening it and causing it to thin and bulge outward into a cone shape.

The cornea is the clear, dome-shaped outer covering of the eye. It’s responsible for focusing incoming light onto the retina at the back of the eye to enable clear vision. So, when keratoconus develops, the change in the cornea’s shape directly impacts the way light is focused.

Keratoconus often results in nearsightedness and high levels of astigmatism — two refractive errors that cause blurry and distorted vision.

If left untreated, keratoconus can lead to permanent corneal damage and even loss of vision.

What Typically Causes Keratoconus?

Keratoconus develops when the collagen fibers that support the cornea begin to weaken. While having a family member with the disease is a significant risk factor, the following conditions can also lead to keratoconus:

  • Eye trauma
  • Eye allergies
  • Excessive eye rubbing
  • Certain eye diseases
  • Marfan syndrome
  • Ehlers-Danlos syndrome
  • Down syndrome
  • Osteogenesis imperfecta
  • Addison’s disease
  • Leber’s congenital amaurosis

The Signs & Symptoms of Keratoconus

The symptoms of keratoconus include:

  • Blurry vision
  • Distorted vision, with straight lines appearing bent or wavy
  • Sensitivity to bright light and glare
  • Red and irritated eyes
  • Increasing difficulty wearing standard contact lenses

Keratoconus tends to be initially detected in teens or young adults in their 20s, but symptoms can develop at any age.

Keratoconus symptoms usually start out mild but grow progressively worse over time — often over a decade or two — until the condition plateaus.

Both eyes are usually affected, and it’s common to have a difference in optical prescriptions between each eye.

Can Keratoconus Cause Vision Loss?

Keratoconus progression causes nearsightedness, astigmatism and visual distortions to worsen.

Eventually, corneal swelling can lead to scarring of the corneal tissue, which diminishes its transparency and increases your risk of vision loss.

Early detection and treatment of this condition are therefore critical for preventing permanent vision loss.

Can Keratoconus Be Corrected?

Initially, blurry and distorted vision can be corrected with custom-fit soft contact lenses or eyeglasses. However, as the condition progresses and your cornea becomes increasingly cone-shaped, these standard methods of vision correction become less effective.

At this point, many patients with mild to moderate keratoconus opt for scleral lenses, an effective, non-surgical method of achieving clear vision.

Severe keratoconus may require a corneal transplant procedure to replace your damaged cornea with a healthy donor cornea.

Scleral Lenses for Keratoconus

Custom designed scleral lenses help patients with corneal irregularities achieve dramatic improvements in visual acuity and comfort. Scleral lenses vault over the cornea and rest on the sclera while avoiding the diseased cornea. This creates a new optical surface instead of the damaged cornea and prevents discomfort by resting on the sclera of the eye. Moreover, the reservoir of pure saline solution between the back surface of the lens and the front of the cornea ensures that the eye is always in a liquid environment – making it optimal for healing.

Don’t let keratoconus impact your quality of life. We can help you achieve clear, comfortable vision with scleral contact lenses.

If you or a loved one has been diagnosed with keratoconus, call Ives Eyecare Center today to schedule a scleral lens consultation.

Our practice serves patients from Murrysville, West Newton, Delmont, and Pittsburgh, Pennsylvania and surrounding communities.

4 Facts You Should Know About Scleral Lenses

Woman wearing Scleral Lenses scenic viewDo you have keratoconus or another type of corneal irregularity due to a medical condition or post-surgical complications? Are you considering giving up conventional contacts due to dry eye syndrome?

Consider scleral contact lenses! Contact Ives Eyecare Center in Murrysville to learn more and to discover a new sense of freedom with sclerals!

What Are Scleral Contact Lenses?

Sclerals are customized rigid gas permeable lenses that are wider than conventional lenses. Their name reflects the fact that they vault over the cornea and rest on the sclera, the white part of the eye.

Scleral contact lenses are 14-24 mm in diameter, while regular contacts are 9mm. This gives sclerals room to accommodate irregularly shaped corneas and provides a reservoir of moisture to soothe dry eyes.

4 Essential Facts About Scleral Contact Lenses

1. Sclerals Are the Right Fit for Irregularly Shaped Corneas

Keratoconus, astigmatism and complications from eye surgery can all result in an irregular-shaped cornea, and wearing contact lenses when your eyes are hard to fit can be challenging. Because sclerals are larger than regular contacts and don’t sit on the sensitive cornea, they provide lots of space and a comfortable fit.

2. Scleral Contact Lenses Can Reduce Dry Eye Symptoms

If you have dry eye syndrome, you may be tempted to give up on wearing contacts altogether. Scleral lenses are ideal for people with dry, itchy and irritated eyes. A lubricating pool of saline solution inside each scleral lens can reduce or even eliminate dry eye discomfort.

3. Sclerals Create a Wider Field of Vision

The width of sclerals not only makes them more comfortable but can extend your field of vision. Their diameter can expand your optic zone and make your peripheral vision sharper and clearer.

4. Sclerals Are Durable and Long-Lasting

Rigid gas permeable contact lenses, including scleral lenses, last longer than conventional soft contacts. Their durable materials are designed to resist wear and tear, which is also why scleral lenses don’t require frequent replacements.

Enjoy the convenience and clear vision scleral lenses by scheduling an appointment with Ives Eyecare Center and discover whether scleral lenses are the right choice for you.

Our practice serves patients from Murrysville, West Newton, Delmont, and Pittsburgh, Pennsylvania and surrounding communities.

 

Frequently Asked Questions with Dr. Paul Ives

Q: Can I exercise with scleral lenses?

  • A: Scleral lenses are ideal for people who lead active lives—whether you’re a professional athlete or just like to pass a ball around with friends at the park. Thanks to their greater width, scleral lenses stay in place on the eye more than standard lenses while simultaneously providing clear crisp vision. That said, scleral lenses aren’t recommended for martial arts and other sports with a higher-than-usual rate of facial injuries.

Q: If I have keratoconus, can I avoid corneal surgery with scleral lenses?

  • A: A study published in the Journal of Ophthalmology (2018) that examined 51 patients with advanced keratoconus found that 40 of them didn’t need surgery after wearing scleral lenses. In fact, wearing them reduced the need for corneal transplant or keratoplasty by half during a 5-year period.

6 Things To Know About Keratoconus

happy couple in winterKeratoconus is an eye disease that causes the cornea, the clear dome-shaped front surface of the eye, to become misshapen and bulge. This progressive disease usually occurs in both eyes and affects approximately 50-200 in every 100,000 individuals.

People who have keratoconus often experience problems like blurred vision, distorted vision, night blindness and sensitivity to light. Clear vision correction for keratoconus can be challenging to achieve because the irregular corneal shape makes it difficult or impossible for standard eyeglasses or contact lenses to provide you with sharp vision.

Thankfully, there are ways for people with keratoconus to achieve clear and comfortable vision, something we explore below, along with several other key points about keratoconus.

1. Everyone has different risk factors for developing keratoconus

Some risk factors for developing keratoconus include:

  • Hereditary predisposition
  • Eye rubbing
  • Other medical conditions like Down syndrome, allergic dermatitis and connective tissue disorders
  • Eye inflammation

2. Keratoconus can develop at any age

Although most cases of keratoconus are first diagnosed in adolescence or young adulthood, it can appear during any stage of life. That’s why regular eye exams are crucial, even if your vision seems clear and your eyes appear to be healthy.

3. Early diagnosis is key

This rings true for almost every eye disease, especially keratoconus. Catching it early in its tracks can allow the eye doctor to implement various treatments to slow down its progression during the initial stages, when this condition tends to worsen more rapidly.

4. Keratoconus progresses at different rates throughout life

Keratoconus progression varies from person to person, and one person can experience varying degrees of progression in each eye. Some patients live with mild keratoconus their entire lives, while other patients develop severe keratoconus early on.

Often, optometrists will recommend that patients undergo certain procedures to strengthen the cornea and prevent or slow down further progression.

5. Keratoconus can be treated with surgery or scleral contact lenses

Corneal cross-linking surgery is an effective option to provide enhanced strength to the cornea and is the only FDA-approved method of stopping or slowing keratoconus progression. However, if the condition develops into severe keratoconus, a corneal transplant may be the best option for treating the condition and restoring clear vision.

Scleral contact lenses offer another option to surgery. They are ideal for patients with early or moderate levels of keratoconus because they safely and effectively correct vision without irritating the misshapen cornea. In fact, studies have shown that patients with keratoconus who wear scleral contact lenses greatly reduce their risk of needing keratoplasty (corneal transplant surgery).

The large diameter of scleral contact lenses allows them to vault over the sensitive corneal tissue and then also coat the cornea in a nourishing reservoir of fluid for optimal comfort and visual clarity. Because eye rubbing and corneal irritation are significant risk factors for the progression of keratoconus, the protective qualities of scleral lenses can help to minimize keratoconus progression.

6. You can live a normal life with keratoconus

With the proper care and treatment from your optometrist, keratoconus shouldn’t stop you from living your life to the fullest. Although it can be discouraging to experience vision problems that can’t be resolved with standard lenses or glasses, know that there are other options available.

At Ives Eyecare Center, we help patients with keratoconus and other corneal abnormalities achieve crisp and comfortable vision using scleral contact lenses and other specialty lenses.
