If 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 Norwalk Vision Scleral Lens and Keratoconus Center eye doctor in Norwalk 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. David Folman and Dr. Martin Arkin and talk to us about getting fitted with scleral lenses.

Our practice serves patients from Norwalk, Weston, New Canaan, and Westport, Connecticut and surrounding communities.

 

 

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.

 

Scleral 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. David Folman and Dr. Martin Arkin at Norwalk Vision Scleral Lens and Keratoconus Center to see whether scleral lenses are the right solution for you.

Our practice serves patients from Norwalk, Weston, New Canaan, and Westport, Connecticut and surrounding communities.

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.

Scleral 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 Norwalk who can assess whether scleral contacts are right for you, look no further than Norwalk Vision Scleral Lens and Keratoconus Center. 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!

 

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.

Our practice serves patients from Norwalk, Weston, New Canaan, and Westport, Connecticut and surrounding communities.

Keratoconus 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 Norwalk Vision Scleral Lens and Keratoconus Center, 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 Norwalk, Weston, New Canaan, and Westport, Connecticut and surrounding communities.

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 Norwalk Vision Scleral Lens and Keratoconus Center, 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.

World 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 Norwalk Vision Scleral Lens and Keratoconus Center to learn more about scleral lenses and to discover ways we can help you manage your keratoconus.

 

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.

Norwalk Vision Scleral Lens and Keratoconus Center provides scleral lenses to patients from Norwalk, Weston, New Canaan, and Westport, Connecticut and surrounding communities.

If 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
• Frequent eye strain

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 Norwalk Vision Scleral Lens and Keratoconus Center, 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.

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.

For 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.

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.
