Everything You Need To Know About Keratoconus

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

Our practice serves patients from McDonough, Stockbridge, Ellenwood, and Jonesboro, Georgia 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 Elevated Eyecare in McDonough 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 Elevated Eyecare and discover whether scleral lenses are the right choice for you.

Our practice serves patients from McDonough, Stockbridge, Ellenwood, and Jonesboro, Georgia and surrounding communities.

 

Frequently Asked Questions with Dr. Santrell Hart-Moreland

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 Elevated Eyecare eye doctor in McDonough 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. Santrell Hart-Moreland and talk to us about getting fitted with scleral lenses.

Our practice serves patients from McDonough, Stockbridge, Ellenwood, and Jonesboro, Georgia and surrounding communities.

 

Frequently Asked Questions with Dr. Santrell Hart-Moreland

 

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. Santrell Hart-Moreland at Elevated Eyecare to see whether scleral lenses are the right solution for you.

Our practice serves patients from McDonough, Stockbridge, Ellenwood, and Jonesboro, Georgia and surrounding communities.

Frequently Asked Questions with Dr. Santrell Hart-Moreland

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.

8 Benefits of Wearing Scleral Lenses

Woman Wearing Scleral LensesScleral contact lenses are rigid gas permeable lenses with an extra-wide diameter. As opposed to standard contacts, scleral lenses vault over the entire cornea, leaving a gap between the lens and the corneal surface before coming to rest on the white part of your eye (your sclera).

They are custom-fit to your eye and are perfect for those with hard-to-fit eyes, astigmatism, keratoconus, severe dry eye, or for those simply seeking more comfort when wearing contact lenses.

Here are 8 reasons why scleral contact lenses may be beneficial for you:

1. Clear Vision For Those With Keratoconus

Keratoconus (keh-rah-toe-cone-us) is an eye disorder in which the round dome-shaped cornea progressively thins and causes a cone-like bulge to develop. The irregular, cone-shaped corneas cannot be properly corrected using glasses or traditional contact lenses. Scleral lenses, on the other hand, sit comfortably sit on the sclera without touching the cornea, while providing sharpness, clarity and comfort in vision.

2. Great Solution for Hard-to-Fit Eyes

Patients with an irregularly shaped cornea, whether due to natural causes, an eye condition (i.e. keratoconus or astigmatism) or complications following surgery (such as LASIK), can occasionally develop vision problems that cannot be corrected with glasses or soft contact lenses. Consider scleral lenses for a comfortable, secure fit, and improved vision.

3. Relief for Dry Eyes

Though generally used to treat corneal irregularities and refractive errors, scleral lenses can also provide immense relief to dry eye patients.

These custom-designed lenses vault over the cornea and rest on the sclera while avoiding the cornea. The liquid reservoir between the lens and the cornea provides a continuous moist environment that protects the cornea and provides relief for those with dry eyes.

4. Stable Vision

The lenses’ super-size diameter ensures that they stay centered and stable on your eye, which also prevents them from popping out easily, even if you play sports or lead an active lifestyle.

5. Wide Visual Field and Reduced Glare

Because of their large diameter, scleral lenses are more stable and have a wider optic zone than other lenses. They offer a more accurate perception of peripheral vision and help minimize glare and sensitivity.

6. Eye Protection

The large size of the lens protects your eyes from debris, dust, and allergens, providing a perfect solution if you suffer from eye allergies.

7. Long-Lasting Lenses

These rigid gas permeable contacts are made of high-quality, durable materials made to last for the long haul. Refer to your eye doctor to discuss the right time to replace your lenses.

8. Cost-effective

Because they’re custom fit, the cost of scleral lenses is usually higher than standard contact lenses. However, sclerals last up to 2 years, so they’re more cost-effective in the long term. Your insurance coverage may pay for scleral lenses if you have a corneal disease or other eye condition.

Ready to Try Sclerals?

If you’re looking for an eye doctor in McDonough who can assess whether scleral contacts are right for you, look no further than Elevated Eyecare. Whether your contacts are uncomfortable or you have a corneal irregularity that makes wearing regular contacts impossible, we welcome you to contact us today to discuss whether sclera lenses are right for you!

 

Frequently Asked Questions with Dr. Santrell Hart-Moreland

Q: Why are regular lenses uncomfortable for people with dry eye syndrome?

  • A: When the contact lenses dry out, they can create discomfort, especially if the eye is also dry. People with dry eye syndrome suffer from itchy, red, burning or a gritty feeling in the eye. That is why scleral lenses are better for dry eye patients than regular contact lenses because they have a wider curve to hydrate the eye and keep it moist, alleviating dryness.

Q: Why is it difficult for people with keratoconus to wear traditional contact lenses?

  • A: Keratoconus is caused by a weakness in the cornea that causes it to bulge forward and compromise vision. Contact lenses help keratoconus patients see properly, and yet, because of the irregular shape of the cornea, it can be difficult to fit them with standard contact lenses. Since scleral lenses are wider and are custom-designed, they are usually the contact lens of choice to correct vision in keratoconus patients.

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

Our practice provides scleral lenses to patients from McDonough, Stockbridge, Ellenwood, and Jonesboro, Georgia and surrounding communities.

Frequently Asked Questions with Dr. Santrell Hart-Moreland

Q: Who else can benefit from wearing scleral contact lenses?

  • A: Scleral contact lenses are ideal for patients with any of the following conditions: corneal abnormalities, severe dry eye syndrome, post-LASIK or corneal transplant, eye allergies, high refractive error or corneal trauma. Speak with your optometrist to find out if scleral lenses are right for you.

Q: Do all optometrists fit specialty contact lenses like sclerals?

  • A: No. If you are interested in scleral contact lenses, be sure to choose an optometric practice that has years of experience fitting specialty lenses. At Elevated Eyecare, we have the knowledge, skill and experience necessary to provide you with the best lenses for your eyes. Call us to learn more or schedule your scleral lens fitting.

6 Tips For Adjusting To Wearing Scleral Lenses

6 Tips For Adjusting To Wearing Scleral Lenses 640×350Congratulations on your new pair of customized scleral contact lenses! As with most new things, there can be a learning curve when getting your scleral contacts to feel and fit just right.

Whether you’ve been prescribed sclerals for keratoconus, dry eye syndrome, corneal abnormalities or other conditions, it can take up to two weeks for you to feel completely comfortable in your new contacts.

Here are some tips to help shorten the adjustment period on your scleral lens journey:

1. Stick to proper hygiene protocol

Even the most perfectly fitted scleral lenses won’t feel right if they aren’t cleaned and cared for properly. Carefully follow the hygiene guidelines prescribed by your optometrist without cutting any corners. Although it may seem tedious at first, your efforts will be well worth the results.

2. Practice makes progress

The only way to make inserting and removing your lenses second nature is to wear them. Don’t be discouraged if it takes a bit more time to insert them than you’d anticipated. Wearing your sclerals daily will give you the opportunity to practice wearing and caring for your lenses.

3. Try out different insertion tools and techniques

At your initial fitting or follow-up consultation, your eye doctor will show you ways to safely and comfortably insert your lenses. Some patients prefer using a large plunger, while others prefer the scleral ring or O-ring. If neither of these recommended techniques are working for you, seek advice from your eye doctor.

4. Overfill the lens

A common problem that many patients encounter when they begin wearing scleral contact lenses is how to get rid of tiny air bubbles that get trapped in the lens’ bowl. Try filling up the lens with the recommended solution until it is almost overflowing. That way, you’ll have enough fluid left in the lens even if some spills out when you bring it up to your eye.

5. Give it time

If your scleral lenses feel slightly uncomfortable upon insertion — don’t worry. It’s recommended to wait 20-30 minutes to allow them to settle on the eye’s surface before attempting to readjust or remove them. Of course, remove them immediately and try again if you feel significant discomfort.

6. Follow up with your optometrist

Even once you leave your optometrist’s office, we encourage you to remain in touch with your eye doctor if something doesn’t feel right or if you have any questions regarding your scleral lenses.

Frequently Asked Questions with Dr. Santrell Hart-Moreland

Q: What are scleral contact lenses?

  • A: Scleral contact lenses are rigid gas permeable lenses with a uniquely large diameter. They rest on the sclera (whites of the eyes) instead of the cornea, making them a more comfortable and stable option for people with corneal irregularities or dry eye syndrome. Scleral contacts hold a reservoir of nourishing fluid between the eye’s surface and the inside of the lens, providing the patient with crisp and comfortable vision.

Q: Who is an ideal candidate for wearing sclerals?

  • A: Patients with keratoconus, corneal abnormalities, ocular surface disease (dry eye syndrome) and very high refractive errors can all benefit from scleral lenses. Moreover, those with delicate corneas due to disease or after surgery find scleral lenses to be comfortable and therapeutic, as the lenses don’t place any pressure on the sensitive corneal tissue.

World Keratoconus Day + Keratoconus Treatment Options

world keratoconus day November 10 640×350World Keratoconus Day is dedicated to raising awareness about keratoconus (KC), as well as educating and advocating for those living with keratoconus and ectatic corneal disorders.

Keratoconus, or KC, is a degenerative non-inflammatory eye condition affecting the cornea. In KC, the cornea, which is normally dome-shaped, gradually becomes thinner and bulges out as it begins to assume a cone shape.

Keratoconus tends to develop during the early teens, with mild symptoms. As the disease progresses, the cornea’s shape changes to a point where wearing regular contact lenses is no longer an option and eyeglasses cannot fully correct one’s vision.

Fortunately, with the right contact lenses, those with keratoconus can once again see the world clearly and comfortably.

Keratoconus and Contact Lenses

In its early stages, people with keratoconus can usually wear glasses or standard soft contact lenses to correct resulting astigmatism and improve clarity. As the condition progresses, however, your eye doctor will prescribe the most suitable contact lens to accommodate a cone-shaped cornea to provide you with the clearest vision possible.

There are a variety of contact lens options for keratoconus, all of which depend on the severity of the condition.

1. Soft Toric Lenses

Astigmatism can be corrected with soft toric lenses, a comfortable and effective solution during the early stages of KC. However, this may not be a good treatment option as the condition worsens.

2. Custom Soft Contact Lenses

Custom soft contacts are an improvement over soft toric lenses since they are designed to match the exact contour of your cornea. Soft contact lenses can be custom-made for KC patients and may eliminate the need for glasses by fully correcting astigmatism.

3. Gas Permeable Contact Lenses

Gas permeable contact lenses (hard lenses) allow more oxygen into the eye than standard soft lenses. A gas permeable lens has a somewhat different shape than soft contact lens alternatives, as it rests on the cornea, and because the lens is hard, it creates a new optical surface. These lenses are suitable for people with moderate KC.

4. Hybrid Contact Lenses

These lenses are a cross between hard and soft lenses. The hard center provides a flat surface, which helps alleviate the issues associated with a misshapen KC cornea. The lens is rendered more comfortable by the soft outer ring. Hybrids combine the convenience and comfort of soft lenses with the crisp, clear vision of rigid gas permeable contacts.

5. Scleral Lenses

Scleral lenses are larger than standard hybrid, gas permeable or custom soft contact lenses. They vault over the cornea and rest on the sclera, the white of the eye. The advantage of scleral lenses is that they do not sit on the cornea, which removes any rubbing and irritation on the corneal bulge. This reduces the risk of corneal injury from the contact lens.

Furthermore, as the scleral lens vaults above the cornea, the reservoir of pure saline solution between the underside of the lens and the front of the cornea keeps the eye in a liquid environment at all times. This enables the eye to receive an abundance of oxygen.

While both rigid gas permeable (GP) and scleral lenses deliver enough oxygen to the eyes, scleral lenses provide more comfort and better stability than regular GP lenses. For this reason, scleral contact lenses are a very successful option for people with keratoconus and irregularly shaped corneas.

Treatment for Keratoconus

We offer treatment for keratoconus that is tailored to each patient based on the severity and progression of the condition, as well as the patient’s lifestyle.

Contact Elevated Eyecare to learn more about scleral lenses and to discover ways we can help you manage your keratoconus.

 

Frequently Asked Questions with Dr. Santrell Hart-Moreland

Q: For how many hours can scleral lenses safely be worn in a day?

  • A: Scleral lenses can be worn for 12-14 hours per day. To preserve the greatest possible vision and comfort, some patients may need to remove the lenses, clean them, and reapply fresh saline several times a day.

Q: Can scleral lenses completely correct my vision?

  • A: Scleral lenses hide abnormalities on the eye’s surface and may improve vision over other types of correction. However, you’ll probably need to wear glasses over the lenses to see clearly at all distances, particularly if you’re over 40 and require reading glasses for close work.

Elevated Eyecare provides scleral lenses to patients from McDonough, Stockbridge, Ellenwood, and Jonesboro, Georgia and surrounding communities.

7 Questions And Answers About Astigmatism

7 Questions And Answers About Astigmatism 640×350If you wear glasses or contact lenses, you probably have some degree of astigmatism. But how much do you really know about this all-too-common refractive error?

Below, we answer some of the most frequently asked questions about astigmatism and explain why scleral contact lenses are often prescribed to astigmatic patients.

1. What is Astigmatism?

Astigmatism is a common refractive error caused by a cornea that isn’t perfectly spherical. The cornea is the outer front covering of the eye and is partially responsible for refracting light onto the retina. When the cornea is misshapen, it refracts light incorrectly, creating two focus points of light entering the eye. Since the light is no longer focused on the retina, it results in blurred vision at all distances.

2. What are the Symptoms of Astigmatism?

The main symptom of astigmatism is blurred vision, but it can also cause symptoms like:

  • Objects appearing wavy or distorted
  • Squinting
  • Headaches
  • Poor night vision

3. How Common is Astigmatism?

Astigmatism affects approximately 1 in 3 individuals around the world. Most people with myopia (nearsightedness) or hyperopia (farsightedness) also have some level of astigmatism.

4. What’s the Difference Between Astigmatism, Nearsightedness and Farsightedness?

Although all 3 of these refractive errors negatively affect visual clarity, they are caused by different mechanisms.

Astigmatism is a result of a non-spherical cornea, which causes two focal points and blurry vision. Myopia occurs when the corneal focusing power is too high and the light focuses in front of, instead of directly, on the retina. Hyperopia occurs when the corneal power is too weak, so the light rays focus behind the retina, not on it. Both myopia and hyperopia can occur with a spherical cornea.

5. How is Astigmatism Corrected?

In cases of mild to moderate astigmatism, the blurred vision can be easily corrected with prescription glasses or contact lenses. But for patients with high levels of astigmatism, standard contact lenses may not be an option. Toric contact lenses are a popular choice for patients with mild or moderate astigmatism due to their unique focusing features and oblong shape. Scleral contact lenses are suitable for moderate to severe astigmatism.

Refractive surgery is also an option, but comes with the risk of surgical complications.

6. Why Can’t Individuals With High Astigmatism Wear Standard Contact Lenses?

A highly astigmatic cornea has an irregularly shaped surface that isn’t compatible with standard soft contact lenses. Standard soft lenses are limited in the amount of astigmatism they can correct, as these lenses move around on the cornea due to the cornea’s irregular shape. This, in turn, reduces visual clarity and comfort.

Regular hard lenses can often correct astigmatism better than soft lenses, but they, too, have limitations: these lenses are smaller and may also move around too much.

7. Why are Scleral Lenses Ideal For Astigmatism?

Scleral contact lenses are customized to each patient. They have a larger diameter than standard lenses, and thus cover the entire front surface of the eye. These specialized rigid lenses gently rest on the white part of the eye (sclera) and don’t place any pressure on the sensitive cornea, making them suitable for even highly astigmatic eyes.

Furthermore, scleral contact lenses contain a nourishing reservoir of fluid that sits between the eye and the inside of the lens, providing the cornea with oxygen and hydration all day long. In fact, patients typically report that sclerals provide sharper vision than other types of contact lenses.

Have Astigmatism? We Can Help

If you’ve been told that you have astigmatism and that your current contacts or glasses just aren’t cutting it, ask your optometrist whether scleral contact lenses are right for you.

At Elevated Eyecare, we provide a wide range of eye care services, including custom scleral lens fittings and consultations. Our goal is to help all patients achieve crisp and comfortable vision, no matter their level of astigmatism or corneal shape.

Frequently Asked Questions with Dr. Santrell Hart-Moreland

Q: Can a person outgrow astigmatism?

  • A: About 20% of all babies are born with mild astigmatism, but only 1 of those 5 babies with astigmatism still have it by the age of 5 or 6, at which point it is unlikely to diminish or disappear. Astigmatism can continue to change and even progress as the child grows, but tends to stabilize at around age 25.

Q: Can eye surgery cause astigmatism?

  • A: Yes. For example, cataract surgery may cause or worsen astigmatism as the surgeon makes a tiny incision in the cornea to replace the lens. During the healing process, the cornea may change its shape and lead astigmatism to develop.

Are Your Eyes Sensitive To Light? Consider Scleral Lenses!

Are Your Eyes Sensitive To Light 640×350For some people, standard soft contact lenses are a great way to conveniently correct vision. For those with very dry eyes or corneal conditions like keratoconus, standard contacts simply aren’t an option.

Scleral contact lenses, however, are a great alternative for these patients with hard-to-fit eyes. They provide several benefits, such as reducing sensitivity to light (photophobia).

What Does Light Sensitivity Feel Like?

Patients with keratoconus and other corneal conditions tend to experience discomfort or unclear vision in brightly lit environments, even after undergoing treatment for their conditions.

They may see halos around lights while driving or may not be able to drive at all due to the worsening or clouding of vision that comes with light sensitivity. Bright fluorescent lights, like in an office setting, can trigger eye pain and interfere with their productivity and creativity.

Moreover, a photophobic person may not be able to comfortably look at a computer screen or other digital device. Even with the brightness setting turned all the way down, the light that’s emitted from the screen may be too intense.

How Can I Reduce Light Sensitivity?

While implementing the following suggestions can ease your symptoms of light sensitivity, we recommend that you speak with your optometrist for a more personalized approach.

  • Try to stay out of the sun whenever possible, but when you do go outside, wear dark sunglasses to block out the light.
  • Consider installing filters on fluorescent light sources.
  • Take frequent breaks when using a digital device.
  • Reduce glare in your home by turning mirrors away from light sources and keeping windows clean and streak-free. You may want to consider removing reflective surfaces from your home altogether.
  • Speak with your optometrist about whether scleral contact lenses can help you.

What are Scleral Contact Lenses?

Scleral lenses are larger in diameter than standard lenses and rest on the white part of the eye (sclera). Their large surface area vaults over the entire cornea (the eye’s top layer), and thus avoid placing pressure on the sensitive corneal tissue.

The scleral lens holds a reservoir of nourishing fluid between the inside of the lens and the surface of the eye, providing visual clarity and optimal comfort. In fact, many patients report that they are able to wear scleral contacts for longer amounts of time as compared to standard contacts.

Scleral lenses are customized to fit each individual eye, and are suitable for patients with keratoconus, dry eye syndrome, irregular/excessive astigmatism, Sjorgen’s syndrome, other corneal abnormalities and for those having undergone LASIK surgery.

How Do Scleral Lenses Reduce Light Sensitivity?

Light sensitivity, or photophobia, is a common side effect of several eye conditions, such as dry eye syndrome and keratoconus. When the cornea is irregularly shaped, it doesn’t properly reflect light onto the retina, which can lead to light sensitivity.

Thanks to their unique and customized design, scleral lenses act as a new, accurately curved cornea that is able to reflect light in a healthy way. Because of their large diameter, scleral lenses are more stable and have a wider optic zone than other lenses. They offer a more accurate perception of peripheral vision and help minimize glare and sensitivity.

An irregularly shaped cornea is not the only reasons one experiences photophobia. In fact, there are several conditions that can cause it. Your optometrist will determine what’s causing your discomfort through a comprehensive eye exam and will determine whether scleral lenses are the optimal solution for you.

Frequently Asked Questions with Dr. Santrell Hart-Moreland

Q: How long does it take to adjust to scleral contact lenses?

  • A: Scleral lenses are usually very comfortable right off the bat, but some patients may find that it takes up to 10 days to get used to the lenses. Your optometrist will guide you on how to shorten the adjustment period.

Q: How long do scleral contact lenses last?

  • A: Under normal conditions, scleral lenses last between 1 and 3 years — far longer than standard lenses. Your tear film composition and your lens care habits will influence your lenses’ lifespan.
