6 Things To Know About Keratoconus

happy couple in winter 640×350Keratoconus is an eye disease that causes the cornea, the clear dome-shaped front surface of the eye, to become misshapen and bulge. This progressive disease usually occurs in both eyes and affects approximately 50-200 in every 100,000 individuals.

People who have keratoconus often experience problems like blurred vision, distorted vision, night blindness and sensitivity to light. Clear vision correction for keratoconus can be challenging to achieve because the irregular corneal shape makes it difficult or impossible for standard eyeglasses or contact lenses to provide you with sharp vision.

Thankfully, there are ways for people with keratoconus to achieve clear and comfortable vision, something we explore below, along with several other key points about keratoconus.

1. Everyone has different risk factors for developing keratoconus

Some risk factors for developing keratoconus include:

  • Hereditary predisposition
  • Eye rubbing
  • Other medical conditions like Down syndrome, allergic dermatitis and connective tissue disorders
  • Eye inflammation

2. Keratoconus can develop at any age

Although most cases of keratoconus are first diagnosed in adolescence or young adulthood, it can appear during any stage of life. That’s why regular eye exams are crucial, even if your vision seems clear and your eyes appear to be healthy.

3. Early diagnosis is key

This rings true for almost every eye disease, especially keratoconus. Catching it early in its tracks can allow the eye doctor to implement various treatments to slow down its progression during the initial stages, when this condition tends to worsen more rapidly.

4. Keratoconus progresses at different rates throughout life

Keratoconus progression varies from person to person, and one person can experience varying degrees of progression in each eye. Some patients live with mild keratoconus their entire lives, while other patients develop severe keratoconus early on.

Often, optometrists will recommend that patients undergo certain procedures to strengthen the cornea and prevent or slow down further progression.

5. Keratoconus can be treated with surgery or scleral contact lenses

Corneal cross-linking surgery is an effective option to provide enhanced strength to the cornea and is the only FDA-approved method of stopping or slowing keratoconus progression. However, if the condition develops into severe keratoconus, a corneal transplant may be the best option for treating the condition and restoring clear vision.

Scleral contact lenses offer another option to surgery. They are ideal for patients with early or moderate levels of keratoconus because they safely and effectively correct vision without irritating the misshapen cornea. In fact, studies have shown that patients with keratoconus who wear scleral contact lenses greatly reduce their risk of needing keratoplasty (corneal transplant surgery).

The large diameter of scleral contact lenses allows them to vault over the sensitive corneal tissue and then also coat the cornea in a nourishing reservoir of fluid for optimal comfort and visual clarity. Because eye rubbing and corneal irritation are significant risk factors for the progression of keratoconus, the protective qualities of scleral lenses can help to minimize keratoconus progression.

6. You can live a normal life with keratoconus

With the proper care and treatment from your optometrist, keratoconus shouldn’t stop you from living your life to the fullest. Although it can be discouraging to experience vision problems that can’t be resolved with standard lenses or glasses, know that there are other options available.

At Scleral Lens and Keratoconus Center At Eye Boutique Optometry, we help patients with keratoconus and other corneal abnormalities achieve crisp and comfortable vision using scleral contact lenses and other specialty lenses.

The Link Between Myopia Progression and COVID Confinement

The Link Between Myopia Progression and COVID Confinement 640×350Several months into the COVID-19 pandemic eye doctors began to notice that children’s myopia was worsening. Researchers set out to learn whether there was, in fact, a link between the pandemic and increased myopia progression, and if so, why.

How The Pandemic Affected Children’s Vision

A recent study published in JAMA Ophthalmology (2021) found that children aged 6 to 13 experienced an increased rate of myopia progression since the beginning of the pandemic, and the lockdowns and restrictions that accompanied it.

The researchers examined the rate of myopia progression from 2015 to 2020 in more than 120,000 children from 10 elementary schools, based on school vision screenings. By the end of the study, children were shown to have significantly higher rates of myopia progression in 2020 than in previous years.

The higher rate of progression was especially severe in children between the ages of 6 and 8. Researchers theorized that the children’s earlier stage of visual development might have been the crucial factor.

Other studies have already determined that children who spend at least 2 hours a day outdoors experience less myopia progression than their peers who stay mostly indoors.

Researchers from the National Eye Institute found that children who spent significant time outdoors — about 14 hours a week — significantly reduced their chances of needing glasses for myopia. Among children with two myopic parents, the chances of needing glasses are roughly 60% if they don’t spend significant time outdoors. However, this study found that, after spending the prescribed 14 hours per week outside, the same children’s risk of myopia dropped to around 20%.

Similar results appear in a study published by the journal of the American Academy of Ophthalmology (February 2019), that shows a significant link between the amount of time children spend engaged in near-work tasks and increased myopia progression.

Taken together, these studies give us a clearer picture of the challenges children have faced during the COVID-19 pandemic, and why myopia rates in children have soared.

What Can Parents Learn From All Of This?

Parents should make an effort to encourage their children to go outside as often as possible and to spend more time away from screens and other near-work tasks. Moreover, progressive myopia in childhood has been linked to heightened risks of developing sight-robbing eye diseases later in life, such as glaucoma, macular degeneration and cataracts.

If you’re concerned about your child’s myopia, make an appointment with their eye doctor as soon as possible, as delays in seeking professional advice can make myopia management more challenging in the future.

Our practice offers myopia management to patients from Santa Clara, Sunnyvale, San Jose, and Milpitas, California and surrounding communities.

Can Restricting Online Gaming Time Reduce Myopia Progression?

Two kids playing online gamesThe Chinese government recently implemented a new policy that’s sparked conversations about childhood myopia and online gaming.

Under the policy, Chinese children and teens under the age of 18 are only permitted to play online video games for one hour on weekend evenings and public holidays — a significant reduction compared to their previous online gaming allotment. This restriction includes all forms of video games, from handheld devices to computer and smartphone gaming.

The government hopes to combat a common condition called online gaming disorder, or video game addiction, which affects more than 30% of children in China. Another potential benefit of limiting online gaming may be a reduction in childhood myopia progression, something we explore below.

The Link Between Online Gaming and Myopia Progression

Myopia, or nearsightedness, is a condition that causes blurred distance vision. Several factors contribute to the onset and progression of myopia, including genetic and environmental.

Several studies have found that screen time, along with other forms of near work, is associated with higher levels of myopia and myopia progression in children.

According to a study published in the British Journal of Ophthalmology (2019), children who engage in screen time for more than 3 hours per day have almost 4 times the risk of becoming myopic. Younger children, around ages 6-7, are even more susceptible to experiencing screen-related nearsightedness, with 5 times the risk compared to children who don’t use digital screens.

Limiting screen time may also encourage children to spend more time outdoors in the sun, a protective factor against developing myopia and slowing its progression.

In The Sydney Adolescent Vascular and Eye Study (2013), researchers found that spending at least 21 hours outdoors per week was more important for delaying the onset of myopia than limiting near work in both younger and older children, although both were effective.

What’s the Bottom Line?

Although online gaming can give children a sense of community and togetherness, excessive online gaming can increase a child’s risk of developing myopia and contribute to its progression.

The good news is that parents can make eye-healthy choices for their children that can have lifelong benefits. Limiting near work activities like online gaming and other screen time, and encouraging your children to play outdoors can significantly reduce their chances of developing high (severe) myopia.

How Myopia Management Can Help

The best thing that parents can offer their children to prevent myopia and halt its progression is a custom-made myopia management treatment plan with an eye doctor.

Whether or not myopia has set in already, we can help preserve your child’s eye health and lower their risk of developing sight-threatening eye diseases like glaucoma, cataracts, macular degeneration and retinal detachment in the future.

6 Tips For Adjusting To Wearing Scleral Lenses

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

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

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

1. Stick to proper hygiene protocol

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

2. Practice makes progress

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

3. Try out different insertion tools and techniques

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

4. Overfill the lens

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

5. Give it time

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

6. Follow up with your optometrist

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

To learn more or to schedule a scleral lens consultation, call Scleral Lens and Keratoconus Center At Eye Boutique Optometry today!

Scleral Lens and Keratoconus Center At Eye Boutique Optometry provides scleral lenses to patients from Santa Clara, Sunnyvale, San Jose, and Milpitas, California and surrounding communities.

Frequently Asked Questions with Dr. Somi Oh

Q: What are scleral contact lenses?

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

Q: Who is an ideal candidate for wearing sclerals?

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

Why Ortho-K Is A Great Alternative To LASIK

Why Ortho K Is A Great Alternative To LASIK 640×350Most people elect to have refractive surgery like LASIK for the hassle-free, crisp vision it provides. But did you know that you can achieve the same results as LASIK without undergoing surgery?

Orthokeratology, commonly referred to as ortho-k, safely eliminates the need for daytime glasses or contact lens wear by correcting myopia (nearsightedness), and is a popular alternative to LASIK surgery.

What Is Ortho-K?

Ortho-k uses rigid gas-permeable contact lenses to gently and safely reshape the front surface of the eye, the cornea, for clear daytime vision. These specialized lenses are designed to be worn overnight while you sleep, and removed in the morning, leaving you with corrected, stable vision throughout the day.

These custom-designed lenses work by gently applying light pressure to the epithelial layer of the cornea and molding its shape to alter its focusing power.

What are the Advantages of Ortho-K Over LASIK?

Lower Risk of Complications

Any medical device or procedure involves some risk of complications. Both ortho-k and LASIK have associated risks, but those of LASIK are considered more serious.

LASIK complications, while rare, can leave patients with corneal disorders, such as astigmatism or severe dry eye syndrome and — more commonly — visual problems like glare, distortion and seeing halos around lights.

In contrast, the risks associated with ortho-k lenses are no different from those connected to any other rigid contact lenses. Poor hygiene is the biggest risk factor for developing contact-lens irritation and complications.

Orthokeratology is Reversible

LASIK surgery is not reversible, and in the event of complications, further medical procedures may be necessary to correct any resulting problems.

Ortho-k, on the other hand, is non-invasive and completely reversible if you ever decide to cease treatment. After a few nights of not wearing the lenses, your corneas will slowly revert back to their original, natural shape.

Better For Dry Eyes

If you have symptoms of dry eye syndrome like dryness and irritation, you may want to think twice before undergoing LASIK. A common side effect of LASIK is dry eye syndrome, and many people who already have the condition are advised to not have refractive surgery.

Dry eye syndrome can also make it uncomfortable to wear standard contact lenses.

Ortho-k is great for people with mild to moderate dry eyes because there’s no need to wear eyewear, such as standard contacts, during the day.

More Cost-Effective

Both LASIK and ortho-k will most likely save you money in the long term, as eyeglasses, contact lenses and other related expenses are no longer incurred. That said, in most cases, the up-front expenses of ortho-k lenses are about half the cost of LASIK surgery.

The exact cost of ortho-k lenses will vary depending on many factors and the degree of your refractive error.

Reduce Myopia Progression

Myopia, or nearsightedness, significantly increases the risk of developing sight-threatening diseases like glaucoma, cataracts, retinal detachment and macular degeneration later in life. The higher (worse) the myopia, the greater the risk. As myopia progresses and worsens, the risks further increase.

Slowing myopia can effectively reduce this risk. Myopia can continue to worsen into a person’s 20’s, and at least 10% of nearsighted adults from ages 20 and older will still experience some degree of myopia progression.

Ortho-k has been clinically proven to slow the progression of myopia in children and young adults, making it an excellent treatment for nearsightedness.

LASIK, on the other hand, offers no such benefits. Refractive surgeries simply alter the focusing power of the cornea to produce clear vision, while ignoring the underlying problem that causes the eyeball elongation associated with myopia.

LASIK is only offered to those whose eyes have stopped growing, usually people 21 and older. So, unlike ortho-k, it generally cannot slow the myopia progression in teens and young adults.

In fact, many teenagers and young adults who are interested in eventually choosing LASIK use ortho-k lenses to stabilize their myopia and increase their chance of successful LASIK outcomes in their 20s, once their eyes stop growing.

Interested in Ortho-K? We Can Help!

If you are interested in correcting your vision without surgery or the need to wear daytime contact lenses or glasses, contact us to learn if ortho-k lenses are right for your eyes and lifestyle.

Frequently Asked Questions with Dr. Somi Oh

Q: Who is a candidate for Ortho-K?

  • A: Children (ages 8 and above) and adults with mild to moderate nearsightedness/astigmatism who want clear vision without daytime eyewear are great candidates for orthokeratology. Ortho-k is also a great option for athletes who require stable vision without worrying about eyewear that can be damaged.

Q: Are there any disadvantages of Ortho-K?

  • A: Ortho-k lenses must be cleaned after each use to maintain hygiene and reduce the risk of contact lens-related problems. Occasionally, ortho-k lenses aren’t suitable for patients with very high prescriptions.

World Keratoconus Day + Keratoconus Treatment Options

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

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

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

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

Keratoconus and Contact Lenses

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

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

1. Soft Toric Lenses

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

2. Custom Soft Contact Lenses

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

3. Gas Permeable Contact Lenses

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

4. Hybrid Contact Lenses

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

5. Scleral Lenses

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

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

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

Treatment for Keratoconus

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

Contact Scleral Lens and Keratoconus Center At Eye Boutique Optometry to learn more about scleral lenses and to discover ways we can help you manage your keratoconus.

 

Frequently Asked Questions with Dr. Somi Oh

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

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

Q: Can scleral lenses completely correct my vision?

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

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.

Have Astigmatism? We Can Help

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

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

Frequently Asked Questions with Dr. Somi Oh

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.

Scleral Lens and Keratoconus Center At Eye Boutique Optometry serves patients from Santa Clara, Sunnyvale, San Jose, Milpitas, and throughout California.

 

Frequently Asked Questions with Dr. Somi Oh

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.

5 Important Eye Care Tips For Kids

Your child’s ability to see the world relies on healthy eyes. By teaching them how to care for their eyes, you help protect them from injury and ensure their eyes and vision remain healthy in the long run. Here are our 5 top eye care tips for kids.

Good Eye Care Habits for Children

1. Maintain a Healthy Diet and Drink Plenty of Water

A nutritious diet and healthy eyes go hand in hand. Encourage your child to eat healthy foods like fresh fruits and vegetables, and prioritize foods rich in vitamin A found in green leafy and yellow vegetables. Eggs are also rich in important nutrients, containing vitamin A, lutein, zeaxanthin, and zinc, all vital for eye health.

Another thing to look out for is hydration. Proper hydration plays a key role in maintaining healthy eyes and a healthy body, so make sure your child drinks plenty of water (the appropriate amount will vary according to your child’s age, level of physical activity and weather conditions).

2. Wear Eye Protection

Physical activity is enjoyable and healthy, but make sure your child is wearing the right protective eyewear, like safety goggles, anytime they participate in sports or activities that could cause an eye injury (i.e. playing ball, hockey, carpentry). Wearing a helmet for sports like riding a bicycle protects against concussions, which can result in lingering vision problems, and are usually preventable.

Furthermore, provide your child with good UV-blocking sunglasses to protect their eyes from the sun’s UV radiation. Staring directly at the sun, or the light rays reflecting off water and snow, can potentially cause retinal burns, in addition to long term damage.

3. Give The Eyes a Rest

Staring at the school board and school books all day, followed by playing video games or watching TV in the evening can cause eye strain. Be sure your child gets sufficient sleep to allow their eyes to rest. Replace evening activities with those that don’t require intense eye focusing: going to the park, playing outdoors with friends, or simply lying down with their eyes closed while listening to music or an audiobook.

4. Reduce Time Spent on Digital Devices

Spending time on digital devices and staring at screens is an integral part of our lives. Playing video games, watching videos on their smartphones and playing computer games, all require the eyes to fixate for extended periods of time, which can lead to digital eye strain, headaches and even dry eyes.

Experts believe that the number of hours spent on screens is the driving force behind the myopia pandemic. Try to reduce the amount of time your child spends on the screen by getting your child to participate in other activities, such as sports. If you are worried about the hours your child is spending on a screen myopia management can mitigate their risk of developing future eye problems.

5. Get Their Eyes Checked Regularly

School-aged children’s vision can change often, and unexpectedly, until the late teenage years. Left uncorrected, poor eyesight can interfere with learning, and cause behavioral and attention issues.

Getting a routine eye exam is important as it can uncover vision problems, detect eye conditions early on, and significantly increase the odds of preserving long-term eye health. For those who wear glasses or contacts, it’s important to check for any changes and update the prescription as needed.

Q&A

My kid frequently rubs their eyes. Is that bad?

Kids often rub their eyes, especially if they have allergies, irritated eyes, or they feel like something is stuck in their peepers. Rubbing can scratch the cornea, and transfer bacteria from the child’s hands to their eyes, causing an eye infection.

Instead of rubbing, have them wash their eyes with cool water to flush out any foreign body or irritant, and ease inflammation. If the problem persists, contact your child’s optometrist.

Other than reducing screen time, is there anything else I can do to maintain eye health & safety?

When you’re at home, keep an eye on your children’s playtime and make sure that none of their toys — or the toys at their friends’ homes — are sharp. Sharp plastic swords and toys with jagged edges can cause serious eye injuries.

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

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. Somi Oh today!

Frequently Asked Questions with Dr. Somi Oh

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.
