Scleral Contact Lenses for Sjogren’s Syndrome

What Is Sjogren’s Syndrome?

Sjogren’s syndrome is an autoimmune disease that causes extreme dryness that affects much of the body, including the eyes. In addition to dryness of the mucous membranes, Sjorgren’s syndrome can cause pain, exhaustion, nerve damage and blood cancer.

About 4 million Americans have the disease, 90% of them women. An additional 3 million may be living with the disease without knowing it, according to the Sjogren’s Syndrome Foundation. In fact, an estimated 1 in 10 patients with dry eye symptoms have Sjogren’s syndrome.

Why Sjogren’s Syndrome Causes Dry Eyes

Individuals with the syndrome have inflammation of the lacrimal glands, which causes them to produce a lower quantity of tears. Lower tear volume means that irritants that would ordinarily be washed away by tears remain on the ocular surface, leading to inflammation, irritation and, if left untreated, corneal scarring.

Many individuals with Sjogren’s syndrome also have other autoimmune diseases, such as lupus, celiac disease or rheumatoid arthritis.

Eye Symptoms Related to Sjogren’s Syndrome

In those with Sjogren’s syndrome, having dry eyes is a given.

dizzyOther common symptoms include:

  • Burning eyes
  • Sensitivity to light
  • Blurry vision
  • Eye strain and fatigue
  • Blepharitis – an inflammation of the eyelids
  • Discomfort while wearing regular contact lenses

How Is Sjogren’s Syndrome Diagnosed?

Because the symptoms are varied and develop gradually, it can take several years for those with Sjogren’s syndrome to be diagnosed with the disease.

However, eye doctors are often the first to suspect the condition since dry eyes are a key symptom of the disease.

After taking your medical history and providing a thorough eye exam, your eye doctor may perform the Schirmer’s test to see whether your tear glands are working properly.

During the test, the eye doctor will place special paper inside your lower eyelids while you keep your eyes closed for a few minutes. Once the paper is removed, the doctor will measure the amount of liquid on the paper.

Another test, which uses dye to make your tears more visible, measures how quickly your tears evaporate.

How Scleral Lenses Alleviate Dry Eyes

Individuals with dry eye syndrome, whether caused by Sjorgren’s syndrome or another condition, often complain that traditional contact lenses irritate their eyes. That’s because traditional contacts dry out easily and compensate by drawing moisture away from the eye.

Scleral lenses, which are gas-permeable, do the exact opposite. They form a protective dome over the cornea that conserves saline solution. The solution acts as a liquid buffer between the lens and the cornea’s surface. That, in turn, alleviates the irritation, itchiness and redness that are the hallmarks of dry eye.

Due to their larger diameter and custom fit, scleral lenses don’t move around as much as conventional lenses. This boosts visual acuity and reduces irritation.

If your eyes feel parched and gritty, contact Dr. Heather Shear O.D. for a comprehensive eye exam to determine whether you have dry eye syndrome and to discuss whether your symptoms could be due to Sjorgren’s syndrome.

Scleral Lenses For Keratoconus And Other Eye Conditions

The cornea, which is the clear tissue on the eye’s outermost surface (covering the pupil and the iris), bends and focuses light going into the eyes. However, for those with irregularly-shaped corneas, the light entering the eye is not properly focused — which results in distorted vision.

Thankfully, scleral lenses offer excellent visual acuity and comfort for those with corneal irregularities, due to their large shape, unique features and customized fit.

Scleral Lenses for Keratoconus

Keratoconus (keh-rah-toe-cone-us) is an eye disorder in which the round dome-shaped cornea progressively thins, causing a cone-like bulge to develop.

Because patients with keratoconus have irregular, cone-shaped corneas, glasses cannot be used to properly correct vision. The ideal solution, therefore, are scleral contact lenses. They sit on the sclera without touching the cornea, while providing sharpness, clarity and comfort.

Scleral Lenses for Severe Dry Eye

People suffering from severe dry eye can find therapeutic benefits from transitioning to custom designed scleral lenses. Scleral lenses tackle three factors simultaneously: they provide vision correction, they protect the eye, and they serve a therapeutic purpose by lubricating the eye.

Scleral lenses also decrease pain, discomfort, eye redness and itchiness in those with dry eyes.

Scleral Lens RA Transplant 1280×853Scleral Contact for Astigmatism

Astigmatism is a refractive error caused by irregular corneal curvature, resulting in blurred and distorted vision. Scleral lenses offer exceptional vision correction in patients with astigmatism, whether by birth, following post-refractive surgery, or due to other corneal procedures. The lenses improve visual acuity and comfort while keeping eyes hydrated all day long.

Scleral Lenses for Myopia and Presbyopia

Scleral contacts are ideal for anyone with severe nearsightedness or farsightedness. For presbyopic patients, scleral contacts can be designed as multifocal contacts to correct nearsightedness and farsightedness simultaneously. Because scleral lenses are firmly positioned on the eye, they provide significantly more comfort when compared to standard multifocal lenses.

Mini Scleral Contacts Vs. Full-Size Scleral Contact Lenses

All scleral lenses rest on the white part of the eye, the sclera. However, Dr. Heather Shear O.D. will customize the scleral lenses by determining the exact diameter and space needed between the cornea and sclera. Certain scleral lenses may have a space of a few millimeters (mini scleral lenses), while standard scleral lenses are larger, full-sized lenses. Larger scleral lenses are typically recommended for highly irregular corneas.

Ask Us About Scleral Lenses

If you struggle with keratoconus, astigmatism, dry eyes or any of the other conditions listed above, ask your Northwestern Eye Associates Scleral Lens and Keratoconus Center doctor about scleral lenses. Dr. Heather Shear O.D. will patiently assess and explain your condition to you, and will perform a specialized, scleral lens custom-fitting to ensure that you receive the best fit for optimal visual clarity and comfort.

Scleral Lenses for Giant Papillary Conjunctivitis (GPC)

Giant Papillary Conjunctivitis (GPC) is an inflammatory reaction that occurs on the eyelids when proteins are secreted in your tears. These proteins then form a filmy coating on contact lenses that not only makes wearing them uncomfortable but also irritates the eyelids, causing an inflammatory reaction.

In the initial phase of the condition, the inside of your eyelid may become red, itchy, swollen and irritated, but as time goes on, bumps (also called papillae) will develop, occasionally growing to the size of a pimple. GPC can thus make wearing contact lenses irritating and uncomfortable.

Fortunately, GPC isn’t permanent. Wearing scleral lenses not only reduces GPC’s effects but, unlike other lenses, can prevent a recurrence. If you suspect that you have GPC or are simply interested in seeing whether scleral lenses are right for you, speak with Dr. Heather Shear O.D. today.

What Causes GPC?

  • Wearing certain types of contact lenses heightens the risk of developing GPC
  • Protein deposits or other substances on the contact lenses
  • A contact lens, artificial eye, or exposed stitches that rub against the lower eyelid
  • An allergic reaction to either contact lenses or their cleaning products
  • Asthma, hay fever, or other allergies coupled with the use of contact lenses

Can People With GPC Wear Contact Lenses?

Yes. However, those with GPC have more difficulty finding a contact lens that doesn’t further exacerbate the irritation.

Gas permeable (GP) lenses, such as scleral lenses, are highly recommended since proteins don’t accumulate on GP lenses the way they do on soft lenses. This ensures that gas permeable lenses remain cleaner and are therefore less likely to cause an inflammatory reaction.

Another alternative is daily disposable lenses, as they are discarded after a single day of wear. This prevents protein deposits from accumulating on the lenses.

Monthly soft lenses tend to retain protein deposits over time, no matter how well they’re cleaned on a daily basis.

Scleral Lenses for GPC

Due to their large size, scleral lenses are more stable on the eye than conventional GP lenses, and are therefore less likely to dislodge from the eye. Moreover, all scleral lenses are customized and made with highly breathable gas permeable material so that plenty of oxygen reaches the front of the eyeball. 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 moist environment. It’s no surprise that scleral lenses consistently rank at the top of the charts when it comes to providing sharp visual acuity, comfort and healthy eyes.

Why Do Scleral Lenses Help Prevent GPC?

The customization of scleral lenses is one of the key factors in preventing GPC. Because the lens is properly fitted to the specific eye, and the vault over the cornea is filled with artificial tears, it prevents debris from entering while soothing GPC symptoms simultaneously. Furthermore, those who have highly sensitive eyes and are prone to experiencing allergic reactions can benefit from wearing scleral lenses, as they protect both the tear film layer and are easier to clean than other GP lenses.

Speak with Dr. Heather Shear O.D. to learn how to care for your lenses and avoid developing GPC. If you’re susceptible to getting GPC, make sure to schedule follow-up visits with Dr. Heather Shear O.D..

Can GPC Develop in Scleral Lens Wearers?

Although the chances are much lower than in conventional contact lenses, giant papillary conjunctivitis may at times develop with scleral lenses due to potential lens surface debris buildup. For those with allergies, it is ideal to use a peroxide cleaning solution as it provides in-depth disinfection.

Make sure to regularly visit Dr. Heather Shear O.D. to have your cornea monitored in order to prevent GPC from worsening or recurring.

Scleral Lenses for Astigmatism

Scleral lenses are a great nonsurgical solution that provides exceptional vision correction in patients with astigmatism, whether by birth, due to post-refractive surgery, or other corneal procedures. Astigmatism is a refractive error caused by irregular corneal curvature, resulting in blurred and distorted vision. Scleral lenses allow astigmatic patients to experience improved visual acuity and comfort while keeping eyes hydrated all day.

If you have been told that your astigmatism is too severe to wear contacts, ask Dr. Heather Shear O.D. about scleral contact lenses. At the Northwestern Eye Associates Scleral Lens and Keratoconus Center in Mt. Dennis, we work hard to give each patient a superior contact lens fit and know that these lenses can truly make a difference in our patients’ lives.

What is Astigmatism

Histoplasmosis Retinopathy ThumbnailAstigmatism is a common type of refractive error caused by an irregularly shaped cornea. The abnormal cornea causes light to enter unequally onto the retina, which results in blurred or distorted vision, eye strain, headaches, squinting and eye irritation. People are either born with this condition or can develop it later in life.

This condition typically occurs with myopia (nearsightedness) or hyperopia (farsightedness) and can be easily diagnosed using a simple eye exam.

Astigmatism falls into three categories:

  • Myopic (nearsighted) astigmatism: For the myopic, light rays focus in front of the retina, leading objects in the distance to appear blurred. Myopic people who have astigmatism experience further blurring and vision distortion due to the refractive error caused by mismatched curvatures of the cornea or lens.
  • Hyperopic (farsighted) astigmatism: For the farsighted, light focuses beyond the retina. Individuals with hyperopia and astigmatism experience blurred and distorted vision and have difficulty focusing on objects that are up close.
  • Mixed astigmatism: In people with mixed astigmatism, one curvature of the cornea or lens focuses light to the front of the retina while the other focuses light to the back of the retina.

Astigmatism falls into the regular or irregular camp:

Most cases of astigmatism are regular, meaning that the front surface of the eye is oval-shaped. Irregular astigmatism is often caused by scarring of the cornea, keratoconus or from certain types of eye surgeries.

Can People With Astigmatism Wear Contact Lenses?

In cases of moderate to severe astigmatism, sometimes the distortion is too severe to be compensated for properly by soft contact lenses, which simply conform to the irregular shape of the cornea. Scleral lenses, on the other hand, sit on the sclera – not the cornea. They are rigid and maintain their shape regardless of the corneal dimensions. This allows the eye to properly focus light and thus ensures the sharp vision and exceptional comfort. The liquid reservoir that gets trapped underneath the scleral lens masks corneal astigmatism and ensures a stable fit.

What are Scleral Lenses?

Scleral lenses get their name from the way they fit on the eye. The sclera is the white part of the eye, and these lenses rest on the sclera while the lens itself vaults over the cornea.

Scleral lenses have become an important therapeutic strategy in the visual rehabilitation of patients with irregular corneas, such as astigmatism. The liquid reservoir between the lens and the cornea neutralizes astigmatism and provides a continuous moist environment that protects the cornea from exposure to air and friction from blinking.

Scleral lenses offer better comfort, breathability and improved visual acuity due to their rigid optical surface and a shape designed specifically for each patient’s eye. We have found that for our patients with astigmatism, scleral lenses have proven to be the best solution in providing sharp and comfortable vision all day long.

Are Scleral Lenses for Astigmatism Expensive?

Scleral lenses are custom-fit to each eye, and though the fees for fitting scleral and the cost of the lenses are higher than traditional lenses, their life span and benefits offset the costs.

Coverage rates and restrictions vary among providers, and if considered a medical necessity, many insurance companies will cover the cost of scleral lenses. That said, every country and state has its own restrictions and regulations. Consult with our eye care team at the Northwestern Eye Associates Scleral Lens and Keratoconus Center to discuss your specific payment options and cost of scleral lenses.

Specialized optometrists, such as Dr. Heather Shear O.D., are trained in fitting scleral lenses for excellent, effective vision correction, and help patients with astigmatism and other corneal irregularities enjoy great vision and comfort with specialty lenses.

Specialty Contact Lenses For Presbyopia 1280×480

Specialty Contact Lenses For Presbyopia

As we get older our vision starts to change. Between the ages of 40 and 50, almost all people develop presbyopia (age-related farsightedness), which makes nearby objects appear blurry.

Reading glasses used to be the only option for contact lens wearers with presbyopia who wanted to perform tasks that require good near vision such as reading a book or menu.

Nowadays, several specialty contact lenses offer patients with presbyopia clear near and distance vision for ultimate visual comfort and convenience.

Contact Lenses for the Farsighted

Monovision

This is a vision correction technique in which the contact lens in one eye corrects for distance vision and the other eye for near vision. Basically, each lens has a different prescription.

Scleral Lenses

Scleral contacts are large-diameter gas-permeable contact lenses that vault over the entire corneal surface and rest on the white part of the eye (sclera) instead of the cornea.

Scleral contacts can also be designed as multifocal contacts for presbyopic patients to correct both farsightedness and nearsightedness. When compared to regular multifocal lenses, scleral lenses are firmly positioned on the eye, offering substantially better stability and comfort.

Multifocal

Patients who wear multifocal contact lenses are able to see at all distances without sacrificing depth perception. Those who participate in outdoor activities, use the computer regularly or don’t like using reading glasses to view their smartphone, tablet, or newspaper might consider multifocal contact lenses.

There are two basic types of multifocal contact lenses: simultaneous vision design and segmented vision design.

1. Simultaneous vision design – Concentric rings of distant and near powers encircle a primary viewing zone in the lens’s center. The central viewing zone is typically used to view distant things, although there are also center-near designs. Under other circumstances, the dominant eye is fitted with a center-distance design, whereas the non-dominant eye is fitted with a center-near design. These multifocal contacts are similar to concentric multifocal lenses, but instead of discrete rings of distance and near power encircling the lens’s center, the multifocal lens power gradually changes from distance to near (or near to distant) from the lens’s center to the periphery. Aspheric multifocal contact lenses are similar to progressive eyeglass lenses in this way.

2. Segmented vision designs – Bifocal and trifocal eyeglass lenses have a similar design to segmented multifocal contact lenses. The upper and center zones of the lens feature a zone for distant vision, while the lower half of the lens has a zone for near vision. A noticeable line in the lenses separates the distant and near zones.

These contact lenses are made of rigid gas permeable (GP) contact lens material. These lenses have a smaller diameter than soft contact lenses and rest above the edge of the lower eyelid on a layer of tears. A segmented multifocal contact lens stays in place as your look shifts downward for reading or seeing close objects, allowing you to see through the lower, near-correction part of the lens.

Rigid gas-permeable (RGP)

RGP contact lenses are composed of rigid silicone polymers that allow oxygen to pass through the cornea. Unlike soft contact lenses, they hold their shape and can often provide clearer vision than soft lenses.

Orthokeratology

Orthokeratology, also called ‘ortho-k’ lenses, are lenses that are worn overnight to reshape the cornea. Ortho-k can be used to correct both eyes for distance vision and be used as monovision and multifocal vision.

If you have presbyopia and are looking into your contact lens options, contact Northwestern Eye Associates Scleral Lens and Keratoconus Center to learn more about which specialty contact lenses are right for you.

Our practice serves patients from Mt. Dennis, Toronto, York, and Rockcliffe Smythe, ON and surrounding communities.

Scleral Lenses for Athletes

Clear and comfortable vision is vital in sports—it can make a huge difference to optimizing your game-time performance. Fortunately, scleral lenses offer a way for athletes who need corrective eyewear to achieve their goals, even in contact sports like basketball, football and hockey.

Scleral lenses are custom-fit contact lenses for people with corneal irregularities, hard-to-fit eyes and severe dry eye syndrome, among other conditions. They provide comfort and offer sharp vision on and off the playing field.

Scleral lenses are extremely stable on the eye, as they vault over the cornea and rest on the sclera. Moreover, the reservoir of saline solution between the back surface of the lens and the front of the cornea ensures that the eye remains moist all day long. Furthermore, the lenses’ highly breathable gas permeable material ensures that plenty of oxygen reaches the front of the eye.

What Kind Of Athletes Wear Scleral Lenses?

Scleral lenses benefit athletes who find wearing traditional contact lenses challenging or impossible, and/or who have any of the following eye conditions:

  • Astigmatism
  • Dry eye syndrome
  • Presbyopia
  • Keratoconus
  • Post-refractive surgery (i.e. LASIK, PRK)
  • Giant papillary conjunctivitis (GPC)

Scleral Lenses for Athletes with Keratoconus

Keratoconus is an eye condition in which the cornea thins and weakens over time. This causes a cone-like bulge to develop and an irregular-shaped cornea. Keratoconus can result in increased sensitivity to light, distorted vision, slightly blurred vision and even significant vision loss. Professional athletes diagnosed with keratoconus often worry that the condition could end their career.

Scleral lenses are a long-term solution that helps athletes with keratoconus to continue to perform at their peak with amazing vision. Just ask professional athletes Brandon Williams from the Baltimore Ravens, Steph Curry from the Golden State Warriors, or Diamond DeShields from the Chicago Sky. These star athletes all wear scleral contact lenses and can now show off their true sporting prowess due to their sharp vision.

Do Scleral Lenses Work For All Sports?

When fitted correctly, the edges of these customized lenses fit comfortably under the eyelids, which prevents them from easily falling out. Moreover, because of their stability and extreme comfort, they offer an added advantage for athletes who engage in contact or extreme sports or those with rapid movements, such as in:

  • Basketball
  • Baseball
  • Football
  • Gymnastics
  • Hiking
  • Hockey
  • Rock Climbing
  • Soccer
  • Skiing
  • Tennis

However, scleral lenses are not advised for wrestling, karate, or boxing, other martial arts or any sports where facial injuries are common.

How Can Scleral Lenses Improve An Athlete’s Vision?

Athletes are often exposed to challenging environmental conditions, such as dust, chalk, sand and wind, all of which can lead to discomfort with soft contact lenses. As scleral lenses provide a seal over the eye’s surface, their eyes are much more protected from the elements. Because athletes have demanding visual needs, stable, clear, crisp vision is essential for optimal athletic performance.
