Regular Contact Lenses Not Working for You? Consider Scleral Lenses

Woman wearing scleral lensesIf you have dry eye syndrome, a corneal transplant, keratoconus or who simply find conventional contacts uncomfortable to wear, you may want to try scleral contact lenses. Scleral lenses are larger than standard lenses and vault over the entire surface of the cornea. Because the lens sits firmly on the eye, it offers more comfortable and stable vision than traditional lenses.

Eye Problems That Can Make Contact Lens Wearing Difficult

If your cornea is irregularly sized or shaped, standard contact lenses may not fit you properly or may move when you blink. Furthermore, standard contacts can also cause or exacerbate dry eye symptoms, such as red, irritated, itchy or dry eyes.

Below are common eye conditions that can make contact lens wearing a struggle:

  • Keratoconus
  • Dry eye syndrome
  • Astigmatism
  • Corneal transplant
  • Post-refractive surgery (i.e. LASIK)

Why are Scleral Lenses a Comfortable Alternative?

These oversized lenses provide relief, clear vision, and visual rehabilitation for dry eye, keratoconus, corneal degeneration, eyelid abnormalities, and corneal ectasia, among other conditions. That’s because the custom-designed scleral lenses are fitted to your unique eye shape, providing a superior level of comfort.

Moreover, a fluid reservoir between the lens and the cornea optically neutralizes any corneal irregularities and hydrates the ocular surface, providing a moist and comfortable environment between the eye and the lens.

How Large are Scleral Lenses?

The average size of regular contact lenses is 9mm, which is smaller than the cornea, whereas scleral lenses measure between 14.5mm to 24mm in diameter. This allows the scleral lens to form a dome over the cornea, creating a cushion of tears between the lens and the eye.

What Happens During a Scleral Lens Fitting?

Scleral lenses are custom-fit to each person’s unique eye shape, corneal curves, and contours, providing unparalleled comfort. Their size and shape also ensure stability.

To design the lenses, your The Pacific Eye Care Scleral Lens Center eye doctor in Huntington Beach will take exact measurements of your cornea through a process called corneal topography. This process ensures that your personal pair of scleral lenses allows the right amount of light in and sits stably on the eye, thus offering superior vision, all-day ocular hydration, and increased comfort.

Schedule an appointment with Dr. Walter Yim and talk to us about getting fitted with scleral lenses.

Our practice serves patients from Huntington Beach, Seal Beach, Fountain Valley, and Westminster, California and surrounding communities.

 

Frequently Asked Questions with Dr. Walter Yim

 

Q: Can Scleral Lenses Treat or Cure Keratoconus?

  • A: While scleral lenses aren’t a cure for keratoconus, they are highly effective at correcting vision if you have irregular-shaped corneas or cone-shaped corneas.Because those with keratoconus have irregular, cone-shaped corneas, glasses and standard contact lenses cannot conform to the shape of the eyes and thus cannot adequately correct the patients’ vision. The best solution, therefore, is scleral contact lenses, since they sit on the sclera without touching the cornea and deliver maximal clarity while being perfectly comfortable in most cases.

Q: Can Scleral Lenses Help Improve Vision Following Corneal Transplants?

  • A: Though corneal transplants have a high rate of success, it can take more than a year for the eye to recover from surgery. This is because the eye needs time to adapt to the new cornea, during which time nearsightedness or astigmatism may develop. For this reason, scleral lenses are the ideal choice for clear and comfortable vision following a corneal graft.

Stay Active and See Better With Scleral Lenses

Stay Active and See Better With Scleral Lenses 640×350Scleral contact lenses have long been the way to provide clear and comfortable vision to people with keratoconus, severe dry eye syndrome, irregularly shaped corners and patients recovering from corneal transplants and refractive surgeries.

But did you know that scleral lenses are also a great option for active people who need their lenses to sit securely and not pop out? Many people find that traditional contact lenses don’t provide the stable and clear vision required for their active lifestyle. This is especially true for athletes with high astigmatism who want to achieve a greater level of clarity comparable to LASIK surgery.

Whether you like to run marathons, go skiing or play sports that require sharp vision, scleral lenses can provide the vision correction and peace of mind you’ve been seeking.

What Makes Scleral Lenses Different?

Scleral lenses are hard, gas-permeable contact lenses that settle on the eye in a more stable position than regular soft or hard contacts. That’s because scleral lenses have a larger diameter than standard lenses, so they’re less prone to falling out or moving on the eye.

In addition, these lenses vault over the cornea to rest on the sclera, the whites of the eyes, on a cushion of fluid, providing additional comfort. Your eyes stay hydrated when exposed to harsh winds during winter sports or in hot and dry conditions.

These features make sclerals a good option for active people and athletes.

What Else Are Scleral Lenses Used For?

Scleral lenses are the go-to lenses if you have an irregularly shaped cornea or keratoconus, which causes the lens to thin, bulge and develop a cone-like shape. As keratoconus progresses, patients often can’t achieve clear vision from eyeglasses or regular contact lenses.

The fact that scleral lenses are custom-designed to fit a patient’s eyes can make them the best option for people who can’t wear traditional hard or soft lenses.

Who Is a Good Candidate for Scleral Lenses?

The following people may find a particular benefit from scleral lenses:

  • Active people and athletes who need clear vision and want contacts that will stay firmly in place
  • People with irregular corneas, such as keratoconus
  • Those with dry eye syndrome
  • Post-corneal transplant patients
  • Those who have poor vision due to complications after eye surgery.

Can You Play Sports with Scleral Lenses?

Thanks to their greater width, scleral lenses stay in place on the eye more than standard lenses while simultaneously providing clear crisp vision. Many wearers also find them more comfortable than other contact lenses. This makes sclerals ideal for most sports, including baseball, basketball, cycling and skiing.

There are, however, some direct contact sports, such as karate, boxing and wrestling, where sclerals aren’t recommended due to the risk of eye injury if the lens is damaged.

Do Scleral Lenses Treat Keratoconus?

Scleral lenses aren’t a cure. However, sclerals are highly effective at correcting vision if you have irregular-shaped corneas because the lenses vault over the cornea and rest on the sclera, compensating for the misshapen cornea.

If you love sports, live an active lifestyle, have an irregularly shaped cornea or dry eyes, consult with Dr. Walter Yim at The Pacific Eye Care Scleral Lens Center to see whether scleral lenses are the right solution for you.

Our practice serves patients from Huntington Beach, Seal Beach, Fountain Valley, and Westminster, California and surrounding communities.

Frequently Asked Questions with Dr. Walter Yim

Q: How Can Scleral Lenses Improve An Athlete’s Vision?

  • A: Athletes are typically exposed to challenging environmental conditions, such as dust, chalk, sand and wind. These can all interfere with the comfort of wearing soft contact lenses. Because scleral lenses provide a seal over the eye’s surface, the eyes are better protected from the elements, allowing athletes more stable, clear, crisp vision.

Q: Do Scleral Lenses Cure Keratoconus?

  • A: No. Custom-designed scleral lenses help patients with corneal irregularities, like astigmatism and keratoconus, achieve dramatic improvements in visual acuity and comfort. These lenses vault over the cornea and rest on the sclera, thus creating a new optical surface. Moreover, the reservoir of pure saline solution between the back surface of the lens and the front of the cornea ensures that the eye is always in a liquid environment, ensuring optimal vision and comfort for those with keratoconus.

8 Benefits of Wearing Scleral Lenses

Woman Wearing Scleral LensesScleral contact lenses are rigid gas permeable lenses with an extra-wide diameter. As opposed to standard contacts, scleral lenses vault over the entire cornea, leaving a gap between the lens and the corneal surface before coming to rest on the white part of your eye (your sclera).

They are custom-fit to your eye and are perfect for those with hard-to-fit eyes, astigmatism, keratoconus, severe dry eye, or for those simply seeking more comfort when wearing contact lenses.

Here are 8 reasons why scleral contact lenses may be beneficial for you:

1. Clear Vision For Those With Keratoconus

Keratoconus (keh-rah-toe-cone-us) is an eye disorder in which the round dome-shaped cornea progressively thins and causes a cone-like bulge to develop. The irregular, cone-shaped corneas cannot be properly corrected using glasses or traditional contact lenses. Scleral lenses, on the other hand, sit comfortably sit on the sclera without touching the cornea, while providing sharpness, clarity and comfort in vision.

2. Great Solution for Hard-to-Fit Eyes

Patients with an irregularly shaped cornea, whether due to natural causes, an eye condition (i.e. keratoconus or astigmatism) or complications following surgery (such as LASIK), can occasionally develop vision problems that cannot be corrected with glasses or soft contact lenses. Consider scleral lenses for a comfortable, secure fit, and improved vision.

3. Relief for Dry Eyes

Though generally used to treat corneal irregularities and refractive errors, scleral lenses can also provide immense relief to dry eye patients.

These custom-designed lenses vault over the cornea and rest on the sclera while avoiding the cornea. The liquid reservoir between the lens and the cornea provides a continuous moist environment that protects the cornea and provides relief for those with dry eyes.

4. Stable Vision

The lenses’ super-size diameter ensures that they stay centered and stable on your eye, which also prevents them from popping out easily, even if you play sports or lead an active lifestyle.

5. Wide Visual Field and Reduced Glare

Because of their large diameter, scleral lenses are more stable and have a wider optic zone than other lenses. They offer a more accurate perception of peripheral vision and help minimize glare and sensitivity.

6. Eye Protection

The large size of the lens protects your eyes from debris, dust, and allergens, providing a perfect solution if you suffer from eye allergies.

7. Long-Lasting Lenses

These rigid gas permeable contacts are made of high-quality, durable materials made to last for the long haul. Refer to your eye doctor to discuss the right time to replace your lenses.

8. Cost-effective

Because they’re custom fit, the cost of scleral lenses is usually higher than standard contact lenses. However, sclerals last up to 2 years, so they’re more cost-effective in the long term. Your insurance coverage may pay for scleral lenses if you have a corneal disease or other eye condition.

Ready to Try Sclerals?

If you’re looking for an eye doctor in Huntington Beach who can assess whether scleral contacts are right for you, look no further than The Pacific Eye Care Scleral Lens Center. Whether your contacts are uncomfortable or you have a corneal irregularity that makes wearing regular contacts impossible, we welcome you to contact us today to discuss whether sclera lenses are right for you!

 

Frequently Asked Questions with Dr. Walter Yim

Q: Why are regular lenses uncomfortable for people with dry eye syndrome?

  • A: When the contact lenses dry out, they can create discomfort, especially if the eye is also dry. People with dry eye syndrome suffer from itchy, red, burning or a gritty feeling in the eye. That is why scleral lenses are better for dry eye patients than regular contact lenses because they have a wider curve to hydrate the eye and keep it moist, alleviating dryness.

Q: Why is it difficult for people with keratoconus to wear traditional contact lenses?

  • A: Keratoconus is caused by a weakness in the cornea that causes it to bulge forward and compromise vision. Contact lenses help keratoconus patients see properly, and yet, because of the irregular shape of the cornea, it can be difficult to fit them with standard contact lenses. Since scleral lenses are wider and are custom-designed, they are usually the contact lens of choice to correct vision in keratoconus patients.

6 Things To Know About Keratoconus

happy couple in winterKeratoconus 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 The Pacific Eye Care Scleral Lens Center, we help patients with keratoconus and other corneal abnormalities achieve crisp and comfortable vision using scleral contact lenses and other specialty lenses.

Our practice provides scleral lenses to patients from Huntington Beach, Seal Beach, Fountain Valley, and Westminster, California and surrounding communities.

Frequently Asked Questions with Dr. Walter Yim

Q: Who else can benefit from wearing scleral contact lenses?

  • A: Scleral contact lenses are ideal for patients with any of the following conditions: corneal abnormalities, severe dry eye syndrome, post-LASIK or corneal transplant, eye allergies, high refractive error or corneal trauma. Speak with your optometrist to find out if scleral lenses are right for you.

Q: Do all optometrists fit specialty contact lenses like sclerals?

  • A: No. If you are interested in scleral contact lenses, be sure to choose an optometric practice that has years of experience fitting specialty lenses. At The Pacific Eye Care Scleral Lens Center, we have the knowledge, skill and experience necessary to provide you with the best lenses for your eyes.

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.

Frequently Asked Questions with Dr. Walter Yim

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.

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

Frequently Asked Questions with Dr. Walter Yim

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.

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. Walter Yim at The Pacific Eye Care Scleral Lens Center 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. Walter Yim or one of the knowledgeable staff members at The Pacific Eye Care Scleral Lens Center 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.
