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, Family Eye Care in Old Bridge 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 Old Bridge, New Jersey:

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 can provide. At Family Eye Care in Old Bridge we offer specialized contact lenses that provide clear and comfortable vision, even if you have moderate or severe astigmatism.

What is Astigmatism?

Astigmatism is a refractive condition, meaning, how light is bent and reaches the back of your eye. The cornea, the front part of your eye, bends light onto the retina, at the back of the eye. When the cornea is shaped like a sphere (think of a ball), then all the rays of light can focus onto the retina equally. When the cornea is not shaped like that, we need a special type of lens so that is CAN focus correctly onto the back of the eye.

Symptoms of astigmatism include blurred vision, headaches, eye strain, and difficulties with reading or using digital devices.

Astigmatism may be congenital, meaning that you are born with it, 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 conditions.

Which Contact Lenses Can You Wear With Astigmatism?

Although regular 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 Soft lenses are prescribed for people with mild astigmatism. It may be obvious, but the power in the contact lens, must coincide with the power you need. Patients with higher levels of astigmatism, however, may require a higher level of expertise.

Toric lenses are designed to provide clear vision and a comfortable fit. There are some limitations with toric lenses. First, the range of corrective powers is limited to what the manufacturers produce. Second, the lenses rotate to align to the shape of your cornea. At times that can leading to occasional unstable or varying clarity of vision. Third, all soft lenses are made wit ha high amount of water. That’s what makes them comfortable when we first put them in, but as the day goes on, they tend to lose water. The water evaporates out of the lenses because when we spend time on computer and other digital devices, we tend to blink less and the lenses dry out. Also, we work in heated or air conditioned environments that tend to de-hydrate, meaning, they pull moisture out of the air and out of the contact lenses. That is why people sometimes complain about soft lenses as the day progresses

Toric lenses are available in either soft disposable or Gas Permeable (GP) lens materials.

Gas Permeable Contact Lenses

Gas Permeable (GP) lenses are made of a different material that does not have water in it, so they don’t dry out like soft toric lenses do. Another advantage is that vision is more distinct and ‘crisper’. The lenses last longer. Gas Permeable lenses tend to take a little longer to adjust to initially, but once someone becomes accustomed to them, they really love those lenses.

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. They are individually custom designed for each patient and do not sit on the cornea. They are great for people who have astigmatism and other corneal irregularities. Scleral lenses vault over the cornea and create a liquid reservoir between your cornea and the lens. Your eye stays moist, the cornea is protected, and they give better comfort. The best part is that people can see clearer.

How We Can Help

At Family Eye Care, we can prescribe standard and customized soft toric lenses and we also provide scleral contact lenses that are tailor-made for patients with astigmatism or other corneal irregularities. We use a special instrument, called a topographer, that precisely maps out the surface of the cornea, so we can then design a lens that has the best possibility of obtaining crisp clear vision.

5 Facts About Scleral Lenses

happy teenagers 640Scleral contact lenses are large-diameter gas permeable contact lenses that vault over the cornea and rest on the “white” of the eye (the sclera). In doing so, the lenses form a dome over the irregular cornea that provides clear and comfortable vision for individuals with keratoconus, dry eye and other ocular surface conditions.

Here are 5 facts about scleral lenses and why they are a great choice for many patients.

1- They work when nothing else will.

Patients with an irregularly shaped cornea, whether due to natural causes, an eye condition or complications following surgery, can at times develop vision problems that cannot be corrected using glasses or soft contact lenses. In such cases, scleral lenses provide a more comfortable, stable, secure fit, and improved vision.

For those with keratoconus, scleral contact lenses provide advanced care that resolves visual distortions and creates clear vision while providing a comfortable wearing experience.

In addition to helping those with keratoconus, scleral lenses are also recommended for those with an astigmatism, particularly for high astigmatism that other contacts cannot comfortably correct.

2- Scleral contacts provide relief for those who suffer from dry eye.

Unlike traditional contact lenses, scleral lenses minimize eye irritation. Since they vault over the dry, irritated cornea and sit on the sclera, they offer comfort and clear vision. Sclerals leave a space between the lens and the cornea containing a liquid reservoir of artificial tears that provides a protective cushion that soothes the eye.

This is crucial, because even blinking can irritate the eye or injure the cornea due to the mechanical friction of the eyelids on the cornea. Scleral lenses can act as a shield between a patient’s eyes and their eyelids, protecting the eyes from further irritation or damage.

3- Sclerals are long lasting lenses.

Constructed from high quality, durable materials, these rigid gas permeable contacts typically last 1-3 years. Therefore, while the initial cost of scleral lenses is higher than standard contacts, you’ll benefit from maximum value for your money.

While scleral lenses are long lasting, it is important to book follow up visits with your eye doctor to determine when it’s time to replace them with a new pair, so as not to harm your cornea.

4- Scleral contacts are worth the cost

People assume that because sclerals must be fitted and customized to fit each individual eye, they are exorbitantly expensive. In fact, the lenses are often covered by insurance and certain vision and health savings plans.

These lenses provide enough of an improvement over regular lenses — in both comfort and vision — to justify the investment.

5- Scleral lenses are very comfortable.

Some people mistakenly assume that rigid contacts aren’t comfortable. In reality, scleral contact lenses are very comfortable because they don’t touch the cornea and lubricate the eyes.

If you have irregular corneas, dry eye or hard-to-fit eyes, scleral lenses may be right for you. Find out more about scleral lenses by scheduling an eye exam at Family Eye Care today!

Kerataconus and Coronavirus

Middle Aged Couple Multifocal Contacts

Keratoconus is an eye disease affecting the cornea. The cornea is the clear front part of the eye that is responsible for bending light onto the retina. The retina receives that information and sends it to the brain. In Keratoconus the cornea becomes thin and distorted, and becomes a cone-like shape, hence the term Kerato-Conus. This then causes blurred vision, glare, and a halo affect around lights.

  • Some of the choices to help people with Keratoconus are:
  • Eyeglasses or soft contact lenses for those who have a mild or moderate condition.
  • Scleral lenses that vault over the cornea and rest on the sclera, the white part of the eye.
  • Some benefit from corneal cross linking that helps make the cornea more firm, but it does not correct vision or help people see clearly. It’s purpose is to prevent the progression of the keratoconus.
  • In some cases, a corneal transplant is needed.

Hygiene for Scleral-Lens Wearers in the Coronavirus Era

As always, hygiene is paramount when you handle and wear and contact lenses and that goes for scleral lenses as well. Washing your hands thoroughly before touching the lenses is essential. Cleaning and rinsing the lenses with recommended solutions is equally important.

Wearing scleral lenses and other contact lenses during the COVID pandemic is safe, and it has the benefit of eyeglasses not fogging up while you wear a mask.

Consider taking these added preventative steps:

  • Use disinfectant wipes to clean the counters and other surfaces where you place the scleral-lens cases and solutions. This includes disinfecting the cases and containers of solutions before using.
  • Wash your hands before touching your eyes or removing your lenses.
  • Try not to touch your eyes or face.

We, at Family Eye Care in Old Bridge, NJ, treat patients with Keratoconus, Pellucid Marginal Degeneration, post-corneal transplant, post cross-linking, and after LASIK surgeries that have had less than the best outcomes.

We treat patients from all the surrounding towns: Aberdeen, East Brunswick, Manalapan, Matawan, Marlboro, Monroe, Parlin. Sayreville, South Amboy, South River, Spotswood, Lawrence Harbor, Cliffwood Beach, and patients throughout New Jersey.

Succeeding With Sclerals

Succeeding With ScleralsNormally, the cornea bends light onto the retina so we can see clearly, but certain corneal conditions, such as keratoconus and astigmatism cause the cornea to be distorted and that leads to reduced and blurred vision. The same thing can happen after LASIK, or after a corneal transplant.

That’s precisely what happened to three patients described below. Their corneas were irregular, and the distortion caused them to struggle with vision. Fortunately, with scleral lenses, they, and many others who have a corneal condition, obtain improved clarity, sharper focus along with good comfort. Let’s first explain what scleral lenses are, and how do they improve the sight of those who have distorted or irregular corneas, and then we can see how it impacted their lives.

Irregular Corneas and Scleral Lenses

The cornea has an irregular shape when someone has astigmatism, keratoconus, prior eye surgeries (such as LASIK, cataracts, corneal transplant), trauma, scarring, and Pellucid Marginal Degeneration. Eyeglasses and regular contact lenses are sometimes useless when someone has an irregularly shaped cornea. Scleral Lenses are a non-surgical solution to this problem and are often the only solution. They provide clear vision and better comfort.

The lenses vault over the cornea and rest on the sclera, the white part of the eye, which prevents corneal irritation. It creates a new surface on the eye and replaces the distorted corneal surface. That enables allows light to focus onto the retina, restoring vision and comfort.

When patients have a dry eye, we can prescribe scleral lenses. The scleral lenses creates a reservoir that keeps the cornea moist.

Below are the accounts of how some patients have benefitted from scleral lenses.

Everything Is Now in Focus for Ben

Ben entered was excited to enter college. He made friends and studied hard, but he struggled to read the content on the classroom whiteboard and in his textbooks. This presented challenges similar to what he experienced much of his life. Ben has astigmatism, meaning that his corneas were unevenly curved, and because of that, images and texts appeared blurry. He had to squint in order to see better, and that led to frequent headaches. Ben updated his eyeglass prescription regularly, and tried wearing standard contact lenses, he he still struggled with his vision. He then decided to visit our office.

The scleral lenses are custom designed lenses specifically for that individual. They enabled Ben’s eyes to focus light onto the retina and he was now able to see clearly and effortlessly. He was able to read the board and his textbooks and was ultimately able to graduate from college with honors.

If you or your child have astigmatism, please consider scheduling an appointment to see us in so we can determine if scleral lenses would benefit you.

For Jennifer, Scleral Lenses are the Perfect Fit

Jennifer was 15 when she was diagnosed with keratoconus. Her vision had progressively become worse and she often squinted in order to see more clearly. The reason was that her corneas were becoming thinner and then bulging outward into a cone shape. Jennifer had never worn contact lenses and was hesitant at first. The special lenses were designed and ordered. When the lenses arrived, we spent time teaching her how to insert and remove the lenses until she was comfortable doing so on her own. She now enjoys clear undistorted vision and is significantly less sensitive to light. That enables her to enjoy the outdoors during the day and to more comfortably work on computer and study.

Jake had a Corneal Transplant, but now sees clearly with special scleral lenses

Jake’s corneas had scared and needed a corneal transplant, but even with the transplant, he was not able to see clearly and light bothered him. That, unfortunately, occurs relatively commonly after a corneal transplant. Standard contact lenses were painful to wear and his vision continued to fluctuate. Jake ultimately came to our office and we prescribed customized scleral lenses that enabled him to see clearly and comfortably.

Dr. Roth and Dr. Tiomno of Family Eye Care in Old Bridge prescribe scleral lenses to patients from Old Bridge, Aberdeen, East Brunswick, Manalapan, Matawan, Marlboro, Monroe, Parlin. Sayreville, South Amboy, South River, Spotswood, Lawrence Harbor, Cliffwood Beach, and throughout New Jersey.

When Other Contact Lenses Have Failed, Scleral Lenses May Be the Answer

Girl Beach Contact Lenses

Scleral Lenses vs. Standard Soft Lenses

Standard Soft contact lenses are the most common choice for people who want to see clearly without having to wear glasses. Scleral Lenses are a good choice for individuals who have

  • dry eyes
  • irregularly shaped corneas due to keratoconus, or
  • poor vision and complications after LASIK surgery.

These lenses rest on the sclera (the white part of the eye), and are about the same size as soft lenses. They serve as a new surface over the eye and that is why they restore vision for people who have distortions due to keratoconus or complications after LASIK. Scleral lenses store saline solution between the back of the lens and the front of the cornea and that is why they are give relief to those who suffer from dry eye. Scleral lenses are custom-designed for each eye. They are therefore more stable and less likely to pop out. Scleral lenses correct astigmatism even in people with highly irregular corneal surfaces and are a great option for people that are very nearsighted.

To learn if you have a corneal condition that would benefit from scleral lenses, call our office; 732-679-2020. We help patients from Aberdeen, East Brunswick, Manalapan, Matawan, Marlboro, Monroe, Parlin. Sayreville, South Amboy, South River, Spotswood, Lawrence Harbor, Cliffwood Beach, and throughout New Jersey.

Scleral Lenses Can Prevent Dry Eye, Tiredness, and Discomfort

protect your eyes 640x350It’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.

What are Scleral Lenses?

These rigid gas permeable lenses have an extra-wide diameter that vaults over your whole cornea. In contrast to other contact lenses, they rest on the white part of your eyes (sclera) and not the cornea. As a result, scleral lenses consistently rank at the top of the charts when it comes to providing sharp visual acuity, comfort, and healthy eyes.

Common Contact Lens Complaints

Below we’ll explore the most common contact lens complaints we hear at our practice and ways scleral lenses can prevent them.

End-of-day tiredness and dry eyes

After just 6 to 8 hours of contact lens wear during the day, many contact lens wearers experience tired and dry eyes. Though standard hydrogel contact lenses allow a high concentration of oxygen to permeate the eye, some people need an alternative.

End-of-day eye discomfort can be resolved with scleral lenses, as these custom-designed lenses have a liquid reservoir between the lens and the cornea that provides a continuous moist environment that soothes tired, dry eyes.

Not only does this cushion of moisture lead to a comfortable wearing experience; it also promotes healthy eyes throughout the day, allowing you to wear these lenses for 12 to 14 hours! It is for this reason that many of our patients turn to scleral lenses for unparalleled comfort and all-day ocular hydration.

Chronic dry eye syndrome

Certain dry eye patients may experience painful, red, and swollen eyes. For them, traditional soft contact lenses can be unbearable because they sit right on the irritated cornea. Moreover, these contact lenses tend to act as sponges, soaking up the moisture from the surface of the eye.

If you struggle with dry eye syndrome and have been looking for a more effective treatment method beyond eyedrops and artificial tears, ask your Family Eye Care doctor about scleral lenses.

Feeling the contact lens in the eye

Feeling your contact lenses in your eyes often indicates a poor fitting. Everyone’s eyes are different and when it comes to contact lenses, no size fits all. Furthermore, if lenses are insufficiently curved, they can be dislodged with every blink. This isn’t just uncomfortable — the wrong size lens can damage your cornea.

Because scleral lenses have a large diameter and are custom-made to your eye shape and size, it is almost impossible for scleral lenses to dislodge during normal wear. And since these lenses do not make contact with the surface of your cornea, there is a decreased risk of corneal abrasions.

Operating in dusty environments

Dry, dusty or dirty conditions can cause contact lenses to not only dry out, but can also lead irritants to attach themselves to the lenses. Scleral lenses offer comfort, even in dusty or dirty environments. This is because the lenses cover a large area of the eye, and since the outer layer of the lens protects the eye surface, dust and tiny particles can’t reach it. While not a complete barrier, scleral lenses can provide you with more relief and all-day comfort than traditional lenses.

If you’ve tried traditional contact lenses and have experienced any of the above, or if you’re simply seeking a more comfortable alternative to wear all day, it’s worth considering scleral lenses.

Contact a knowledgeable and experienced eye care professional, Dr. Moshe Roth and Dr. Steffani Tiomno, who will patiently assess and explain your condition to you. Dr. Moshe Roth and Dr. Steffani Tiomno will perform a specialized scleral lens custom-fitting to ensure that you receive the best fit for optimal visual clarity and comfort.

Call the Family Eye Care today to schedule your consultation. We help patients from the Old Bridge, East Brunswick, Woodbridge, and Edison, in the New Jersey area enjoy great vision and comfort with scleral lenses.

This Contact Lens Can Actually Treat Dry Eye Syndrome!

something in my eyeWearing traditional contact lenses can be a convenient method of correcting vision — unless you are suffering from dry eye. Dry eye symptoms, such as red, itchy eyes, or a feeling of having something in your eye, tend to worsen when wearing traditional contact lenses.

There is, however, one type of lens that isn’t only comfortable to wear, but also improves vision and reduces symptoms — it’s called a scleral lens. This lens differs from a conventional contact lens in several ways, most notably in size. Scleral lenses are large custom-fit contact lenses that offer multiple benefits for people with dry eyes and a variety of other eye conditions.

If you are experiencing dry eye symptoms, speak with Dr. Moshe Roth and Dr. Steffani Tiomno to see whether wearing scleral lenses is the best course of action for your condition.

Dry Eye Symptoms

First things first, what does dry eye mean? If you’ve been experiencing any of these symptoms for some time, you may be suffering from dry eye syndrome:

  • Red eyes
  • Itchy eyes
  • Sensitivity to light
  • Mucus in or around your eyes
  • A feeling of dust or sand in your eyes
  • Difficulty wearing contact lenses
  • Watery eyes
  • Blurred vision or eye fatigue

Why Do the Symptoms Occur?

Your eyes are usually covered with a thin film of tears to keep them lubricated and protected. If the lubrication is inadequate, that is, if the quality or quantity of the tears is out of balance, one of the above symptoms may occur.

Dry eye can have many causes, such as certain medical conditions, medications, environmental influences, hormones, and extensive exposure to blue light from digital devices. Long-time contact lens usage may also impact tear quality. Dry eye mostly affects women, particularly upon reaching menopause.

What Are Scleral Lenses?

This gas permeable contact lens is considerably larger than any other contact lens, and due to its size, a scleral lens rests on the sclera—the white part of the eye— without touching the cornea.

As mentioned earlier, when you have dry eye, the cornea is more sensitive than usual, rendering it uncomfortable when a traditional contact lens comes into contact with it. Scleral lenses, on the other hand, cause no friction to the cornea as they do not directly touch it, but rather vault right over it.

Scleral lenses were initially developed for patients who could not wear traditional contact lenses, such as those with high astigmatism, keratoconus, and other corneal irregularities. Over the years, study after study has shown that scleral lenses can improve and even treat dry eye syndrome.

How Does a Scleral Lens Treat Dry Eye?

Standard soft contact lenses absorb moisture from the eye, whereas scleral lenses provide moisture. Furthermore, when inserting a scleral lens into your eye, you first apply a saline solution, which fills the gap between the cornea and the lens. This provides moisture for the irritated eye and promotes healing.

By ensuring consistent hydration of the eye and shielding the cornea from external irritants, scleral lenses provide the eye with the conditions needed to heal. As you can see, scleral lenses can play a therapeutic role in the healing process of dry eye syndrome.

What You Need to Know About Wearing Scleral Lenses With Dry Eye

Most people find that scleral lenses are very comfortable to wear. They do not move around on the eye, and dust particles are less likely to get caught underneath. Caring for, inserting and removing a larger lens, however, involves some practice and calls for a little more caution.

One of the few side effects of dry eye is a higher production of mucus, which can accumulate underneath the lens. As a result, you may have to clean your lenses more frequently to ensure clear vision.

Eye Drops and Scleral Lenses

Artificial tears are a common treatment for dry eye, and you can use them in combination with scleral lenses. However, make sure to consult Dr. Moshe Roth and Dr. Steffani Tiomno regarding which drops to use for your specific case.

To further reduce symptoms and improve the quality of your tears, consider using lid scrubs regularly. Also, warm compresses can provide relief and contribute to improving the tear film.

Where Can You Get Scleral Lenses?

Scleral lenses are custom-made for each patient. At Family Eye Care, we have made scleral lens fitting one of our primary objectives, which is why our practice is equipped with the latest technology and contact lens modalities. This has enabled us to achieve positive results for our dry eye patients.

What Is the Shape of a Healthy Eye and How Does It Affect Vision?

eyes eye care 640x350The human eye is a biological piece of functional art, capable of producing colorful moving three-dimensional images with high precision. At the same time, one can marvel at the aesthetic beauty of the human eye and its shape.

The Shape of a Healthy Eye

In a healthy and perfectly shaped eye, light passes through the cornea and crystalline lens, and is accurately focused onto the retina, located at the back of the gel-filled eyeball. This process enables an image to be passed onto the optic nerve and then the visual cortex of the brain. Accurate focus and convergence depend on the proper shape of each part of the eye. However, eyeballs can be either shortened (hyperopia) or elongated (myopia).

Unhealthy Eye Shapes That Impact Vision

The Myopic Eye

In an elongated myopic eyeball, the distance between the lens and retina is too long, leading the image to come into focus before reaching the retina. As a result, the photosensitive cells of the retina pick up a blurry image.

The Hyperopic Eye

In hyperopia or farsightedness, the opposite is the case. The eyeball is too short, as is the distance that light travels from lens to retina. Therefore, the image comes into focus behind the retina, causing distant objects to appear clear, whereas close ones do not come into proper focus.

The Cornea

While the crystalline lens is flexible and auto-adjusts its shape for proper focus, the cornea is static. A healthy cornea maintains its smooth dome shape. However, if the cornea is weak, the structure of the cornea cannot hold this round shape, causing the cornea to bulge outward and downward like a cone. Perfect curvature of the cornea ensures the correct bending of incoming light onto the lens, whereas inadequate curvature results in a refractive error.

An uneven or irregularly shaped cornea also distorts the image that forms at the retina. Common corneal irregularities include astigmatism and keratoconus.

Keratocoonus Labelled

Scleral Lenses for a Smooth Eye Shape

Scleral lenses are large contact lenses that rest on the sclera — the white part of the eye. The lenses span over the cornea, making them ideal for a deformed cornea as they even out the irregularity to create a perfectly shaped eye.

Contact Dr. Moshe Roth and Dr. Steffani Tiomno at Family Eye Care to learn more about how your eye shape affects your vision. We’ll be happy to discuss the different correction methods available that offer you sharp, comfortable and clear vision all day, every day.

Ever Wonder How People See Following a Corneal Transplant?

Dry Eye Senior Woman 640×350For patients with a damaged cornea, corneal transplant surgery (also called keratoplasty) can help restore clear vision by replacing the original cornea with healthy corneal tissue from an organ donor.

Corneal damage can be caused by:

  • Corneal scarring from infection or injury
  • Keratoconus – an eye disease that causes the cornea to bulge
  • Corneal ulcers
  • Eye diseases, such as Fuch’s dystrophy
  • Clouding or swelling of the cornea
  • Complications following eye surgery

During surgery, either a portion of the cornea or the entire cornea is replaced with healthy tissue. Depending on the type of surgery, stitches may be needed. In all cases, however, a patch will be required to shield the recovering eye for 1-4 days after the procedure. Your doctor will instruct you on which medications to take and how to care for your eye in the days and weeks following the surgery.

If you require a corneal transplant or have already undergone the procedure, speak with Dr. Moshe Roth and Dr. Steffani Tiomno or one of the knowledgeable staff members at Family Eye Care about how to safely regain clear vision after surgery.

How Is Vision Impacted After a Corneal Transplant?

Full recovery from the surgery may take up to a year, and sometimes longer. In the first few months after the procedure, your vision may even get worse before it gets better. As the eye adjusts to the new cornea, you may experience blurred or unstable vision, which will improve with time.

There is also a high chance of developing post-surgery refractive error— such as myopia or astigmatism — as the new cornea may have a different curvature than your original cornea. These refractive errors are generally corrected with either glasses, rigid gas-permeable (RGP) lenses, or scleral lenses. In many cases, scleral lenses are the better choice for post-keratoplasty, and for several reasons (explained below).

Why Are Scleral Lenses the Better Choice After Corneal Transplants?

Scleral lenses have a larger diameter than standard soft or gas-permeable lenses, making them more comfortable to wear while providing clear and stable vision. If there is a high variance in corneal curvature or even a slight elevation at the site of the transplant, RGP lenses may decenter, causing irritation and inflammation. Scleral contact lenses prevent this problem as they don’t sit directly on the cornea, but rather vault over it.

Furthermore, scleral lenses support the eye’s natural healing process due to the reservoir of fluid that sits between the cornea and the back of the lens. This keeps the eye in a constant state of hydration for optimal recovery.
