Everything You Need To Know About Keratoconus

Everything You Need To Know About Keratoconus 640×350If you’ve been diagnosed with keratoconus, our Morton 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 Vintage Optical today to schedule a scleral lens consultation.

Our practice serves patients from Morton, Mayfair, Tremont, and Mackinaw, Illinois 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 Vintage Optical in Morton 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 Vintage Optical and discover whether scleral lenses are the right choice for you.

Our practice serves patients from Morton, Mayfair, Tremont, and Mackinaw, Illinois and surrounding communities.

 

Frequently Asked Questions with Dr. Paul Velting

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.

Regular Contact Lenses Not Working for You? Consider Scleral Lenses

Woman wearing scleral lensesIf you have dry eye syndrome, a corneal transplant, keratoconus or who simply find conventional contacts uncomfortable to wear, you may want to try scleral contact lenses. Scleral lenses are larger than standard lenses and vault over the entire surface of the cornea. Because the lens sits firmly on the eye, it offers more comfortable and stable vision than traditional lenses.

Eye Problems That Can Make Contact Lens Wearing Difficult

If your cornea is irregularly sized or shaped, standard contact lenses may not fit you properly or may move when you blink. Furthermore, standard contacts can also cause or exacerbate dry eye symptoms, such as red, irritated, itchy or dry eyes.

Below are common eye conditions that can make contact lens wearing a struggle:

  • Keratoconus
  • Dry eye syndrome
  • Astigmatism
  • Corneal transplant
  • Post-refractive surgery (i.e. LASIK)

Why are Scleral Lenses a Comfortable Alternative?

These oversized lenses provide relief, clear vision, and visual rehabilitation for dry eye, keratoconus, corneal degeneration, eyelid abnormalities, and corneal ectasia, among other conditions. That’s because the custom-designed scleral lenses are fitted to your unique eye shape, providing a superior level of comfort.

Moreover, a fluid reservoir between the lens and the cornea optically neutralizes any corneal irregularities and hydrates the ocular surface, providing a moist and comfortable environment between the eye and the lens.

How Large are Scleral Lenses?

The average size of regular contact lenses is 9mm, which is smaller than the cornea, whereas scleral lenses measure between 14.5mm to 24mm in diameter. This allows the scleral lens to form a dome over the cornea, creating a cushion of tears between the lens and the eye.

What Happens During a Scleral Lens Fitting?

Scleral lenses are custom-fit to each person’s unique eye shape, corneal curves, and contours, providing unparalleled comfort. Their size and shape also ensure stability.

To design the lenses, your Vintage Optical eye doctor in Morton will take exact measurements of your cornea through a process called corneal topography. This process ensures that your personal pair of scleral lenses allows the right amount of light in and sits stably on the eye, thus offering superior vision, all-day ocular hydration, and increased comfort.

Schedule an appointment with Dr. Paul Velting and talk to us about getting fitted with scleral lenses.

Our practice serves patients from Morton, Mayfair, Tremont, and Mackinaw, Illinois and surrounding communities.

 

Frequently Asked Questions with Dr. Paul Velting

 

Q: Can Scleral Lenses Treat or Cure Keratoconus?

  • A: While scleral lenses aren’t a cure for keratoconus, they are highly effective at correcting vision if you have irregular-shaped corneas or cone-shaped corneas.Because those with keratoconus have irregular, cone-shaped corneas, glasses and standard contact lenses cannot conform to the shape of the eyes and thus cannot adequately correct the patients’ vision. The best solution, therefore, is scleral contact lenses, since they sit on the sclera without touching the cornea and deliver maximal clarity while being perfectly comfortable in most cases.

Q: Can Scleral Lenses Help Improve Vision Following Corneal Transplants?

  • A: Though corneal transplants have a high rate of success, it can take more than a year for the eye to recover from surgery. This is because the eye needs time to adapt to the new cornea, during which time nearsightedness or astigmatism may develop. For this reason, scleral lenses are the ideal choice for clear and comfortable vision following a corneal graft.

Stay Active and See Better With Scleral Lenses

Stay Active and See Better With Scleral Lenses 640×350Scleral contact lenses have long been the way to provide clear and comfortable vision to people with keratoconus, severe dry eye syndrome, irregularly shaped corners and patients recovering from corneal transplants and refractive surgeries.

But did you know that scleral lenses are also a great option for active people who need their lenses to sit securely and not pop out? Many people find that traditional contact lenses don’t provide the stable and clear vision required for their active lifestyle. This is especially true for athletes with high astigmatism who want to achieve a greater level of clarity comparable to LASIK surgery.

Whether you like to run marathons, go skiing or play sports that require sharp vision, scleral lenses can provide the vision correction and peace of mind you’ve been seeking.

What Makes Scleral Lenses Different?

Scleral lenses are hard, gas-permeable contact lenses that settle on the eye in a more stable position than regular soft or hard contacts. That’s because scleral lenses have a larger diameter than standard lenses, so they’re less prone to falling out or moving on the eye.

In addition, these lenses vault over the cornea to rest on the sclera, the whites of the eyes, on a cushion of fluid, providing additional comfort. Your eyes stay hydrated when exposed to harsh winds during winter sports or in hot and dry conditions.

These features make sclerals a good option for active people and athletes.

What Else Are Scleral Lenses Used For?

Scleral lenses are the go-to lenses if you have an irregularly shaped cornea or keratoconus, which causes the lens to thin, bulge and develop a cone-like shape. As keratoconus progresses, patients often can’t achieve clear vision from eyeglasses or regular contact lenses.

The fact that scleral lenses are custom-designed to fit a patient’s eyes can make them the best option for people who can’t wear traditional hard or soft lenses.

Who Is a Good Candidate for Scleral Lenses?

The following people may find a particular benefit from scleral lenses:

  • Active people and athletes who need clear vision and want contacts that will stay firmly in place
  • People with irregular corneas, such as keratoconus
  • Those with dry eye syndrome
  • Post-corneal transplant patients
  • Those who have poor vision due to complications after eye surgery.

Can You Play Sports with Scleral Lenses?

Thanks to their greater width, scleral lenses stay in place on the eye more than standard lenses while simultaneously providing clear crisp vision. Many wearers also find them more comfortable than other contact lenses. This makes sclerals ideal for most sports, including baseball, basketball, cycling and skiing.

There are, however, some direct contact sports, such as karate, boxing and wrestling, where sclerals aren’t recommended due to the risk of eye injury if the lens is damaged.

Do Scleral Lenses Treat Keratoconus?

Scleral lenses aren’t a cure. However, sclerals are highly effective at correcting vision if you have irregular-shaped corneas because the lenses vault over the cornea and rest on the sclera, compensating for the misshapen cornea.

If you love sports, live an active lifestyle, have an irregularly shaped cornea or dry eyes, consult with Dr. Paul Velting at Vintage Optical to see whether scleral lenses are the right solution for you.

Our practice serves patients from Morton, Mayfair, Tremont, and Mackinaw, Illinois and surrounding communities.

Frequently Asked Questions with Dr. Paul Velting

Q: How Can Scleral Lenses Improve An Athlete’s Vision?

  • A: Athletes are typically exposed to challenging environmental conditions, such as dust, chalk, sand and wind. These can all interfere with the comfort of wearing soft contact lenses. Because scleral lenses provide a seal over the eye’s surface, the eyes are better protected from the elements, allowing athletes more stable, clear, crisp vision.

Q: Do Scleral Lenses Cure Keratoconus?

  • A: No. Custom-designed scleral lenses help patients with corneal irregularities, like astigmatism and keratoconus, achieve dramatic improvements in visual acuity and comfort. These lenses vault over the cornea and rest on the sclera, thus creating a new optical surface. 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, ensuring optimal vision and comfort for those with keratoconus.
