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
  • 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.

Frequently Asked Questions with Dr. Jason Holtom

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.

The Eye Studio serves patients from Red Deer, Innisfail, Lacombe, Central, and throughout Alberta.

 

Frequently Asked Questions with Dr. Jason Holtom

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.

Do You Struggle With Contact Lens Comfort? Scleral Lenses May Be the Answer!

boy wearing a gray hoodie 640Most people are familiar with traditional soft lenses, which provide clear vision for those who are nearsighted or farsighted.

In certain cases, particularly for those with corneal irregularities or astigmatism, standard gas permeable (GP) lenses may be recommended. However, people with several eye conditions can’t tolerate standard GPs and find scleral lenses a much better, more comfortable alternative.

What are Scleral Lenses?

Patients with sensitive eyes or corneal abnormalities may benefit from custom-designed scleral lenses, which provide crisp vision and comfort thanks to their unique design.

Scleral lenses are usually recommended for those with keratoconus, severe dry eye syndrome, astigmatism or anyone who find it difficult or impossible to wear standard contact lenses.

Scleral lenses are large gas permeable lenses that vault over the cornea and rest on the sclera, the white part of the eye, instead of the cornea. This creates a new optical surface and prevents corneal irritation. Furthermore, a reservoir of pure saline solution between the back surface of the lens and the front of the cornea keeps the eye hydrated all day long.

Benefits of Wearing Scleral Lenses

Scleral lenses provide comfort, visual acuity and stability.

Stable Vision

With scleral lenses, you’ll experience continual clear vision. Because of their wide diameter, the lenses remain centered on your eye. Even if you play sports or lead an extremely active lifestyle, scleral lenses will stay in place and won’t easily pop out.

Long-Lasting Lenses

These gas permeable lenses are made of high-quality long-lasting materials. As a result, scleral lenses usually last between 1-2 years. While the initial cost of scleral lenses is higher than the cost of regular contacts, they give you more bang for your buck.

Safe and Easy-to-Use

Scleral lenses are easier to insert and remove from your eyes than regular GP lenses, thanks to their large size and rigid material. This also limits the risk of damaging your cornea while handling your lenses.

Comfort for Dry Eyes

It’s not uncommon for certain contact lens wearers to suffer from eyes that feel dry, red, itchy, uncomfortable, and at times very painful. Eye drops and artificial tears can deliver relief, but they are no more than a temporary solution.

One of the best contact lenses for optimal comfort and hydration are scleral lenses, as they simultaneously provide vision correction, protect the eyes, and lubricate them.

If you’ve experienced discomfort while wearing regular contact lenses, you may have keratoconus, irregular corneas, dry eyes or hard-to-fit eyes. Find out whether custom-designed scleral lenses are right for you by scheduling an eye exam at Dr. Jason Holtom today!

The Eye Studio serves patients from Red Deer, Innisfail, Lacombe, and Central, Alberta and surrounding communities.

Frequently Asked Questions with Dr. Jason Holtom

Q: Can you sleep with scleral lenses?

  • A: It’s not recommended to wear scleral lenses while you sleep. Sleeping with your scleral lenses on can cause the tear layer behind the lens to become stagnant, thus increasing the risk of eye infections.

Q: Are scleral lenses more comfortable than standard gas permeable lenses?

  • A: Scleral lenses provide clear vision and long-term comfort for those with irregularly shaped corneas. This is due to their unique design that covers a wider area of the eye while avoiding direct contact with the cornea.

6 Reasons Scleral Lenses Can Manage Your Dry Eye Syndrome

6 Reasons Scleral Lenses Can Manage Your Dry Eye Syndrome 640×350If your eyes are chronically itchy, dry, red or irritated, there’s a good chance you have dry eye syndrome.

Eye drops and artificial tears may provide temporary relief, but they often don’t help individuals with chronic or severe dry eye syndrome. That’s why so many people seek out other treatment options.

One such option is scleral lenses. Although custom-made scleral contact lenses are widely used to correct corneal abnormalities and refractive errors, they can also help patients with intractable dry eye symptoms. Here’s why:

1. Scleral lenses don’t irritate the cornea

Standard contact lenses are typically not an option for people who need vision correction and also have persistent dry eye syndrome. Standard soft lenses sit on the cornea, which can be exceedingly irritating. In contrast, scleral lenses vault over the cornea and sit on the sclera (the white of the eye). The lenses do not come into contact with the corneal surface, reducing discomfort.

2. The scleral lens design ensures constant hydration of the eye

Thanks to sclerals’ unique design, saline solution fills the space between the surface of the cornea and the scleral lens. This provides the eyes with constant hydration. To help lubricate and promote healing of the ocular surface, artificial tears and antibiotics can be administered to the lens’ bowl prior to insertion.

3. Scleral lenses protect the cornea

Dry eye syndrome makes the corneas more susceptible to injury. Due to the mechanical friction of the eyelids on the cornea, even something as basic as rubbing the eye or even blinking can exacerbate any current corneal damage. Sclerals can act as a barrier between a patient’s eyes and their eyelids, as well as the outside environment.

4. Sclerals allow the eye to regain a healthier appearance

Dry eye patients frequently present with eyes that are red or bloodshot. Scleral lenses perform a therapeutic role by providing a shield from the outside world and ensuring a constant supply of hydration. The redness will begin to dissipate once the eyes receive enough moisture.

5. Patients can continue using artificial tears and eye drops while wearing scleral lenses

Patients can continue to moisten their eyes with preservative-free eye drops or artificial tears while wearing scleral lenses. With that said, many patients discover that after they start wearing scleral lenses, they can reduce the frequency of artificial tear use. Some need eye drops only at night, after they have removed their lenses.

6. Scleral lenses can dramatically improve quality of life

Patients with dry eye syndrome can feel worn down by the almost constant discomfort and eye fatigue, not to mention looking tired all the time due to eye redness.

For patients who have suffered from severe dry eye syndrome for months or years, finding relief while enjoying clear and comfortable vision definitely boosts their quality of life.

If you suffer from dry eye syndrome and have been looking for a more effective treatment option, ask Dr. Jason Holtom about scleral lenses. Call The Eye Studio today to schedule your consultation and learn more about these special lenses.

The Eye Studio serves patients from Red Deer, Innisfail, Lacombe, and Central, Alberta and surrounding communities.

Frequently Asked Questions with Dr. Jason Holtom

Q: What are scleral lenses?

  • A: Scleral contact lenses are gas-permeable lenses that sit on the sclera (the white area of the eye) and form a dome over the cornea. This dome forms a new optical surface over the injured, uneven or dry cornea, allowing for sharper and more comfortable vision.

Q: How long do scleral lenses last?

  • A: These rigid gas permeable contacts are made of high-quality, long-lasting materials and typically last 1-3 years. While scleral lenses are more expensive than standard contact lenses, they’re a worthwhile investment, particularly for those with hard-to-fit eyes, keratoconus, astigmatism or dry eye syndrome.

5 Common Keratoconus Questions, Answered

5 Common Keratoconus Questions, Answered 640If you’re reading this, you or someone you care about may have been recently diagnosed with keratoconus. We’ve compiled a few commonly asked questions about keratoconus to help you understand what it is, what causes it, and how your eye doctor can help.

1. What Is Keratoconus?

Keratoconus is a progressive, non-inflammatory disease that causes the cornea to thin and bulge, resulting in a cone-shaped cornea. Over time, this bulge leads to myopia and irregular astigmatism, and vision becomes progressively distorted. Ongoing treatment is crucial to prevent significant vision loss.

2. What Are the Symptoms of Keratoconus?

Many patients aren’t aware that they have keratoconus, which typically begins during the teenage years.

Symptoms of keratoconus include:

  • Difficulty seeing at night
  • Blurry vision
  • Halos and glare around lights
  • Increased sensitivity to bright light
  • Headaches or eye irritation associated with eye pain
  • Progressively worsening vision that’s not easily corrected

3. What Causes Keratoconus?

While there is no one cause of keratoconus, a paper published in Biomed Research International (2015) identified these risk factors:

  • Genetics. About one in 10 people with keratoconus also has a family member with the condition.
  • Inflammation. Irritation and inflammation from allergies, asthma and other atopic eye diseases can lend to the development of keratoconus.
  • Frequent eye rubbing. Intense and frequent eye rubbing is thought to thin out the cornea and can worsen the condition.
  • Underlying disorders. Keratoconus has been associated with several conditions, including Down syndrome, Ehlers-Danlos syndrome, Leber congenital amaurosis, Marfan syndrome and Osteogenesis imperfecta.
  • UV light. UV light can cause oxidative stress, which weakens the corneas in predisposed eyes.
  • Weak collagen. In a healthy eye, small protein fibers called collagen help keep the cornea in a dome-like shape and free from bulges. In the case of keratoconus, the collagen fibers become weak and therefore can’t maintain the shape of the eye, which causes the cornea to bulge.

4. How Is Keratoconus Treated?

Scleral lenses are the most common and successful treatment for patients with keratoconus. These are specialized rigid, gas permeable contact lenses that have a very wide [diameter] and vault over the entire corneal surface, making them effective and comfortable for people with keratoconus.

5. Is There a Cure for Keratoconus?

Currently, there is no cure for keratoconus. However, in most cases, it can be successfully managed.

For mild to moderate keratoconus, scleral contact lenses are typically the treatment of choice, as they provide clear, comfortable vision.

A relatively non-invasive procedure called corneal cross-linking (CXL) can stabilize and strengthen a thinning and irregularly shaped cornea.

At The Eye Studio, we can recommend the best treatment options for your keratoconus, to help preserve your vision, and ensure the highest level of comfort and visual acuity. Call to schedule an appointment to start discussing your keratoconus treatment options.

The Eye Studio serves patients from Red Deer, Innisfail, Lacombe, and Central, all throughout Alberta.

Frequently Asked Questions with Dr. Jason Holtom

Q: Can You Go Blind If You Have Keratoconus?

  • A: Keratoconus does not typically cause total blindness. However, as keratoconus progresses it can cause visual impairment including blurred distance vision, distortion, glare, astigmatism, extreme light sensitivity and even vision loss that can be classified as “legal blindness.

Q: Does keratoconus affect both eyes?

  • A: Yes, in approximately 90% of keratoconus cases, the disease will manifest in both eyes. However, the rate of progression and the timing of the onset of the disease is different for each eye.

4 Reasons Why Scleral Lenses Are a Big Deal

happy girl wearing contact lenses 640Scleral contact lenses have been called “life-changing” and “transformative” by patients who wear them.

What makes these contact lenses so revolutionary?

What Are Scleral Lenses?

Scleral lenses are contacts that vault over the entire cornea and rest on the white part of the eye (sclera). Their diameter is much larger than standard lenses, which adds to their comfort and compatibility with hard-to-fit eyes.

Here’s why they’re gaining popularity in the contact lens world and why patients and doctors are calling sclerals a big deal.

1. Sclerals are Ideal for People with Corneal Irregularities or Dry Eyes

There was a time when patients with corneal irregularities or severe dry eye syndrome weren’t able to wear contact lenses at all, due to the discomfort associated with direct corneal contact. Nowadays, patients with keratoconus, other corneal aberrations or dry eye can successfully wear scleral contact lenses and enjoy comfortable and crisp vision.

Scleral lenses are also great for patients with corneal dystrophy, high astigmatism, Sjorgren’s syndrome, corneal trauma and corneal ectasia, or who have undergone cataract surgery.

2. They’re Completely Custom-Made

Each pair of scleral contact lenses is custom-designed to gently and securely rest on your unique eyes. The fitting process for scleral lenses starts with corneal topography, where the optometrist creates a digital map of your eye’s surface. This information is then used to customize your perfectly fitted pair of sclerals.

3. They Offer Optimal Visual Clarity and Comfort

The liquid reservoir that sits between the lens and the eye helps enhance the visual optics of the lens. Moreover, scleral lenses are made of very high-grade materials and don’t place any pressure on the cornea, delivering ultimate all-day comfort. Many patients have reported that they comfortably wear sclerals for up to 14 hours a day, which is longer than the wear time for standard soft contact lenses.

4. They Promote Eye Healing

Scleral contact lenses protect the eye by surrounding it with an oxygen-permeable, liquid-filled chamber. This hydrating environment gives the eye the moisture and oxygen it needs to stay healthy and ward off outside irritants.

This can also explain why scleral lenses promote healing of the eye’s surface, whether after a corneal transplant or when recovering from a chemical burn or other eye injury.

If you or a loved one have been diagnosed with a corneal condition that prevents you from wearing standard lenses, consider scleral lenses. To schedule an appointment or to learn more, call The Eye Studio in Red Deer today!

The Eye Studio serves patients from Red Deer, Innisfail, Lacombe, Central and throughout Alberta.

Frequently Asked Questions with Dr. Jason Holtom

Q: #1: How long do a pair of scleral lenses last?

  • A: Scleral lenses can last 1-2 years before requiring replacement. Your optometrist will provide you with instructions on how to wear and care for your lenses to keep them feeling fresh and clean, day in day out.

Q: #2: Are scleral lenses expensive?

  • A: Just like any other customized product, scleral lenses tend to be more expensive than standard soft contact lenses. Although they have a higher price point, most patients who wear them will tell you that their comfort, visual clarity and stability make them worth the cost.

Living With Keratoconus | Kenneth’s Story

Kenneth’s Story 640From the time Kenneth was 11 years old, he wore glasses to correct his quickly deteriorating vision. He was always forced to sit at the front of the classroom and felt embarrassed by it. This time in his life marked the beginning of seemingly endless visits to various eye doctors to try and figure out what was causing his vision problems.

Four years later, at the age of 15, Kenneth was diagnosed with keratoconus, a progressive eye disease that affects the shape and condition of the cornea. Kenneth was referred by his ophthalmologist to an optometrist who [specializess] in treating keratoconus.

The optometrist explained that keratoconus is a condition that causes the cornea to thin and bulge out in a cone-like shape, leading to visual impairment. The early stages of this progressive eye disease usually cause mild to moderate vision problems that can be corrected with eyeglasses. But as the cornea’s shape continues to distort, glasses are no longer suitable and rigid contact lenses must be prescribed.

The optometrist prescribed rigid gas permeable contact lenses, which significantly improved Kenneth’s vision. But Kenneth sometimes found his contacts hard to manage, and even uncomfortable at times. People would tell him to just ‘switch back to glasses’ and ‘stop wearing the lenses if they give you so much grief.’

That wasn’t possible. He simply couldn’t see without the contacts.

Thankfully, before Kenneth’s condition progressed to the point where cornea surgery was required, new technology gave him fresh hope.

At the age of 20, Kenneth was fitted for scleral contact lenses for the first time. The day of the fitting was an emotional one for him and his family, as he was truly able to see the world around him in detail—and with great comfort.

Kenneth walked out of the optometrist’s practice, looked around, and saw leaves on the trees for the first time in 5 years. Prior to this, his perception of trees were brown stumps with green shrubbery—but never leaves.

He noticed that the cars driving past him on the street looked astonishingly clean. Nothing seemed faded anymore. Colors were vivid, lines were sharp.

The detail and clarity of each object were genuinely overwhelming for him. His mom, who also suffers from keratoconus, was overcome with emotion as she watched her son visually experience his surroundings in a whole new way.

From that day forward, Kenneth’s life changed drastically. His scleral contact lenses enabled him to function normally and achieve his goals. Wearing his sclerals allows him to work, exercise, socialize and be his authentic self.

Kenneth confesses that when he doesn’t wear his sclerals, his entire personality changes. He becomes timid, quiet and apprehensive.

Having keratoconus will no longer hinder Kenneth from living his best life, and it doesn’t have to hinder you or an affected loved one.

To a person with corneal disease, scleral lenses can be truly life-changing. If you or a loved one has keratoconus or other corneal irregularities, contact The Eye Studio today.

The Eye Studio serves patients from Red Deer, Innisfail, Lacombe, and Central, all throughout Alberta.

Q&A

Q: #1: How do scleral lenses work?

  • A: Scleral contact lenses are hard lenses that have a much larger diameter than standard soft contact lenses. They vault over the entire cornea and rest on the sclera (the white of the eye) so that no part of the lens is touching the cornea itself. The lens holds a reservoir of soothing and nourishing fluid between the eye and the lens, providing the best in visual clarity and comfort.

Q: #2: What other conditions do scleral lenses help with?

  • A: Any patient with irregular corneas can benefit from scleral lenses. They’re also suitable for patients with severe dry eye syndrome, as the fluid reservoir helps maintain comfort and ocular hydration. They’re also great for patients with very high refractive errors (high myopia, hyperopia, or astigmatism). Speak to your eye doctor if you think scleral lenses may be right for you.

A Guide to Scleral Lenses

Vision And Medicine Concept. Accessories For Contact Lenses: Con

Many people can’t wear standard contact lenses. This is especially true of patients with severe dry eye syndrome, keratoconus, irregular astigmatism, among other conditions.

That’s why eye doctors often prescribe scleral lenses to such patients. These specialized rigid, gas permeable contact lenses have a very wide diameter and extend over the entire corneal surface, making them effective and comfortable for people with irregular corneas.

At first, some patients may find scleral lenses to be difficult to insert and remove. However, after some practice, you’ll find it easy to care for your sclerals!

Safety and Hygiene for Scleral Lenses

Handling scleral lenses incorrectly can increase your risk of eye infection. Additional risk factors include improper lens cleaning, poor hygiene, and smoking. Therefore, it’s important to follow your eye doctor’s instructions on how to handle your lenses hygienically.

Before handling, inserting, or removing scleral lenses, make sure to:

  • Always wash your hands thoroughly with non-oily soap or antibacterial-based pump soap and dry them with a clean lint-free towel or paper towel.
  • Sit at a desk or table and place a lint-free cloth down to insert and remove lenses. Avoid bathrooms, as they often contain more germs than other rooms in the home.
  • Inspect your lenses for chips or cracks and protein deposits on the lens surface. If you notice any defects or are unsure whether your lenses are damaged, don’t wear them until your eye doctor has inspected them.

How to Insert Scleral Lenses

  1. Remove your scleral lenses from their storage case and rinse with them with saline. If you’re using a hydrogen peroxide solution, wait at least 6 hours from when the lenses were placed into the storage case for the solution to neutralize. Always rinse with saline before placing the lens on the eye.
  2. Either place the scleral lens between your middle, forefinger, and thumb — known as the tripod method — or secure the lens to a suction tool (plunger) supplied by your optometrist.
  3. Fill half the bowl of the lens with preservative-free saline solution to prevent air bubbles from forming between your eye and the lens. Insert the lens directly onto the center of your eye in a facedown position.
  4. Dry and wipe your lens case with a tissue and leave the case lid off to air dry.

How to Remove Scleral Lenses

There are two methods to remove scleral contact lenses: with your fingers, or with the aid of a plunger. First, to detach your scleral lenses from your eye, press firmly with your finger on your bottom eyelid just below the edge of the lens, then push upwards.

Method 1 – Manual Removal

  1. Try Scleral Lenses Thumbnail.jpg

    Insert a drop of preservative-free saline solution or artificial tears to loosen the lens.

  2. Look down onto a flat surface (a mirror or towel can be placed there).
  3. Use your middle finger to open your eyelid wider than the lens diameter.
  4. Apply pressure to the middle of the lid — as close to the lashes as you can — and push down on the eyelid to move your eyelid under the lens and lever it off the eye.

Method 2 – Suction Tool

  1. While looking at a mirror in front of you, hold your bottom lid open. Wet the tip of the suction tool to allow for better adhesion and attach it to the bottom of the lens.
  2. Using the suction tool, remove the lens by tilting the lens up and out of the eye.

How To Care for Your Scleral Lenses

The number one rule in contact lens care is always to follow the professional advice of your optometrist. If you need any clarification, always contact their office first.

Never ever use tap water in any area of lens care, whether to rinse or fill your lens case. Tap water contains a multitude of dangerous microorganisms, including acanthamoeba, that can cause a severe, painful, and sight-threatening infection. Be sure that your hands are fully dry after using a lint-free towel prior to handling your lenses.

Remove Before Going to Sleep

Most people can comfortably wear scleral contact lenses for up to 12-14 hours at a time. Approximately an hour before going to sleep is the best time to remove the lenses. If your lenses fog up in the middle of the day, it’s best to remove them and try various methods to clear up the fogginess before reinserting.

Use a Peroxide Cleaner

You can sterilize your scleral lenses by immersing them in 3% hydrogen peroxide. Over a period of 6 hours, the catalyst in the case transforms the hydrogen peroxide into water and oxygen gas. This gives your lenses a deep clean and removes the need to rub them, thus decreasing the risk of accidental breakage. Do not use the lenses until they have been immersed for 6 hours, as the un-neutralized peroxide will painfully sting your eyes. Leave the lens case to dry when not in use.

Use a Filling Solution That Is Preservative-Free

When inserting scleral lenses, use unpreserved sterile saline solution by filling the bowl of the lens upon insertion. Don’t use tap water or a preserved solution as these can lead to an eye infection.

Remove Debris Using Multi-Purpose Lens Solution

Once you’ve thoroughly washed and dried your hands, remove your scleral lenses and rub them for 2 minutes in a contact lens case filled with saline solution. This effectively removes microorganisms and deposits, lowering your risk of infection. While scleral lenses are strong, too much force or an incorrect technique can cause them to break.

After rubbing your lenses, thoroughly rinse them using the solution for 5-10 seconds. Then place them in a case filled with fresh solution and leave them to disinfect for at least 4 hours.

Routinely Clean and Replace Your Lens Case

Regularly clean and replace your lens case to prevent infection due to bacterial contamination.

It is recommended to clean the storage case on a daily basis and to replace it monthly or as advised by your eye doctor.

Your optometrist will recommend when to get a new pair of scleral lenses, and will advise you when to schedule follow-up appointments. Failure to show up for scheduled appointments can compromise the lenses’ efficacy.

At The Eye Studio, we can recommend the best wearing schedule for your contact lenses to ensure the highest level of comfort and visual acuity. Always follow the instructions provided by your eye care professional. Call to schedule an eye exam and a scleral lens fitting today.

The Eye Studio serves patients from Red Deer, Innisfail, Lacombe, and Central, all throughout Alberta.

Tips For Wearing Scleral Lenses

Pretty Cheerful Woman Gesturing With Two Fingers Near Eyes. Youn

Scleral lenses are ideal for patients with corneal irregularities, dry eyes, and hard-to-fit eyes. Their uniquely large circumference offers the best in visual comfort and clarity. But wearing and caring for your scleral lenses can take some getting used to.

Below are our top 5 tips for anyone who wears scleral lenses. If you have questions about scleral lenses or any other optometric matter, The Eye Studio in Red Deer is here for you.

1. Lens Hygiene is Top Priority

Keeping your scleral lenses hygienic and free of buildup is key in ensuring the clearest possible vision. When you remove them from your eyes, rub them for several seconds with lens cleaner to remove surface debris and bacteria. Then, rinse them on both sides with saline solution before storing them.

Another hygiene tip: Before handling your lenses, be sure to wash your hands with soap and water, and to rinse and dry them with a lint-free cloth or paper towel. Good hygiene will significantly minimize possible complications and keep your eyes feeling fresh.

2. Manage Your Dry Eye

Many patients with dry eye syndrome (DES) choose to wear scleral lenses for their hydrating and soothing properties. While sclerals can offer substantial relief from their dry eye symptoms, patients shouldn’t forget to seek treatment for their DES.

That’s because scleral lenses help manage dry eye, but don’t actually treat it. So, it’s best to follow up with your eye doctor about any eye drops, medications, or at-home remedies to support healthy tears.

3. Use a Cotton Swab For Cleaning

Patients with long fingernails can find it challenging to thoroughly clean their scleral lenses. Rubbing the inside bowl of the lens with a cotton swab and cleaning solution can effectively remove the buildup from the lens. Then, rinse off the cleaning solution with saline to remove the cleaning solution and any lint from the cotton swab.

4. Try Different Insertion Tools

Is your current insertion method not working as smoothly as you’d like? No worries! Ask your eye doctor about different tools you can use, such as the O-ring or applicator ring.

But please only insert your lens with tools that your eye doctor recommends!

5. Follow Up With Your Eye Doctor

Because scleral lenses are customized, they often require a few visits with your optometrist to optimize their fit. Even after the fitting process is complete, follow-ups will help ensure that your lenses are still in good condition.

If your scleral lenses are giving you any trouble at all, we can help. To schedule your scleral lens consultation, call us today!

Frequently Asked Questions with Our Scleral Lenses Expert in Red Deer, Alberta:

Q: How do scleral lenses work?

  • A: Scleral lenses rest and vault over the entire sclera (white of the eye), encasing a hydrating reservoir in between the lens and the cornea (front surface of the eye). This allows people with irregular corneas to wear contact lenses, since the lens isn’t in direct contact with the cornea itself.

Q: How long do scleral lenses last?

  • A: Scleral lenses generally last 1-2 years, depending on how well you care for them and how your tear film reacts with them. Even so, check-ups every 6 months are recommended to ensure they still fit well and provide clear vision.

Can I Wear Contacts If I Have Astigmatism?

brunette girl smiling 640Many people choose to wear contact lenses to correct their vision due to the freedom and convenience contacts provide. But for those with astigmatism, wearing contact lenses isn’t always simple.

At The Eye Studio in Red Deer we offer specialized contact lenses that provide clear and comfortable vision, even if you have moderate to severe astigmatism.

What is Astigmatism?

Astigmatism is a refractive error caused by an irregularly shaped cornea. The abnormal cornea causes light to disperse unevenly into the eye, leading to blurred or distorted vision. Other symptoms of astigmatism can include headaches, eye strain, and difficulties with reading or using digital devices.

Astigmatism may be congenital, meaning that you are born with the condition, or you can develop it later in life. People with astigmatism usually also have myopia (nearsightedness) or hyperopia (farsightedness), two of the most common refractive errors.

Which Contact Lenses Can You Wear With Astigmatism?

Although traditional soft contact lenses may not be suitable for patients with astigmatism, there are two other types of contact lenses specifically designed for those with unusually shaped corneas.

Toric Contact Lenses

Toric lenses are a popular choice for people with mild astigmatism. Patients with higher levels of astigmatism, however, generally require a higher level of expertise.

Toric lenses are designed to provide clear vision and a comfortable fit. There are two main issues with toric lenses. First, the range of corrective powers is limited, so patients with moderate to high levels of astigmatism may not be able to wear toric contacts. Second, these lenses need to rotate on the cornea to find the correct position and orientation, leading these lenses to occasionally provide unstable or varying clarity of vision.

Toric lenses are available in either soft disposable or rigid gas permeable (RGP) lens materials.

Scleral Contact Lenses

Unlike standard lenses, scleral lenses vault over the cornea and sit on the sclera (the white of the eye). These lenses do not have the issues faced by toric lenses as they are individually designed for each patient and do not sit on the cornea. By vaulting over the cornea, scleral lenses create a liquid reservoir between your cornea and the lens. This dome provides a continually hydrating environment that protects the cornea, promotes healing, and increases comfort.

Scleral lenses have become a staple therapeutic tool in the visual rehabilitation of patients with astigmatism and other corneal irregularities. They also can provide better visual acuity than standard soft lenses thanks to their rigid surface and personalized fit. Scleral lenses have proven to be an excellent solution for patients with astigmatism that appreciate sharp and comfortable vision.

How We Can Help

At The Eye Studio, we can provide you with customized toric or scleral contact lenses that are tailor-made for patients with astigmatism or other corneal irregularities, as well as hard-to-fit eyes. By taking precise and detailed measurements of your cornea, we will be able to ensure a secure fit and crisp, clear vision. To learn more information or to schedule your consultation, call us today.
