Scleral Lenses for Athletes

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

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

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

What Kind Of Athletes Wear Scleral Lenses?

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

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

Scleral Lenses for Athletes with Keratoconus

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

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

Do Scleral Lenses Work For All Sports?

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

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

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

How Can Scleral Lenses Improve An Athlete’s Vision?

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

Scleral Lenses for Astigmatism

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

If you have been told that your astigmatism is too severe to wear contacts, ask Dr. Schnarr about scleral contact lenses. At the Pacific Eye Doctors in Maple Ridge, we work hard to give each patient a superior contact lens fit and know that these lenses can truly make a difference in our patients’ lives.

What is Astigmatism

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

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

Astigmatism falls into three categories:

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

Astigmatism falls into the regular or irregular camp:

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

Can People With Astigmatism Wear Contact Lenses?

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

What are Scleral Lenses?

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

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

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

Are Scleral Lenses for Astigmatism Expensive?

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

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

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

Scleral Lenses for Keratoconus

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

Hence the name keratoconus, from the Greek word ‘kerato’ (cornea) and ‘conus’ (cone-shaped).

Because those with keratoconus have irregular, cone-shaped corneas, glasses 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.

What are Scleral Lenses?

what are scleral lensesCustom designed scleral lenses help patients with corneal irregularities achieve dramatic improvements in visual acuity and comfort. Scleral lenses vault over the cornea and rest on the sclera while avoiding the diseased cornea. This creates a new optical surface instead of the damaged cornea and prevents discomfort by resting on the sclera of the eye. 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 – making it optimal for healing.

Both rigid gas permeable (GP) lenses and scleral lenses provide the eyes with sufficient oxygen. However, scleral lenses provide more comfort and stable vision than traditional GP lenses. In most cases, scleral contact lenses are the optimal choice of treatment for patients with keratoconus and irregularly-shaped corneas.

If you have Keratoconus and are interested in scleral lenses, Dr. Schnarr at Pacific Eye Doctors can help. We serve patients from all over Maple Ridge, , and , British Columbia and provides the highest level of care.

Two Major Benefits of Scleral Lenses for Keratoconus

1) Scleral Lenses Provide More Comfort

Our patients report comfort as the most prominent feature of the scleral lens. Throughout the fitting process, we survey our patients on how the lenses feel, and not surprisingly, the usual response we get is “fine” or “I can’t feel them at all”.

The size of a scleral lens is one of the reasons it is more comfortable than a traditional gas permeable contact lens. A traditional contact lens is much smaller, typically 9 -10 mm in diameter. With each blink, this contact lens moves a bit over the cornea and the lid tends to roll over the edge of the lens as well. Many patients report being unable to wear them for more than a few hours at a time due to discomfort.

The scleral lens, on the other hand, is larger in diameter and spreads its weight over a much greater, less sensitive area so that when you blink, the eyelid doesn’t catch the edge of the lens. Moreover, because the lens vaults over the bulging cornea, it protects the cornea from any abrasion caused by blinking or external irritants. Furthermore, the scleral lens is made up of highly oxygen permeable materials and provides a soothing bath of artificial tears that refresh the ocular surface.

2) Scleral Lenses Offer Improved Vision

Patients with keratoconus have a clearer vision with scleral lenses than with glasses. With glasses, patients usually see 20/200, whereas with scleral lenses their vision typically improves to 20/30 or even 20/20. Furthermore, because the lenses sit firmly on the eye, they offer more stable vision than traditional lenses. The scleral lens not only offers comfort but also improves vision acuity.

What Changes Will I Notice with Scleral Lenses?

Once you have been properly fitted for scleral lenses, you can expect to gradually see improvements in clarity, color and detailed contrast between multiple images and objects within your visual field. The comfort you’ll experience will enable you to wear your custom-made scleral lenses all day long so that you can keep doing all the things you enjoy – but with better vision.

Should I See An Eye Doctor Experienced in Fitting Keratoconus Patients with Scleral Lenses?

improved vision with scleral lensesIf you are interested in seeing whether scleral lenses are right for you, make sure that the eye doctor you visit has the knowledge and experience required to correctly fit the lenses on patients with keratoconus. Scleral lenses require precise customization, and every patient’s case of keratoconus varies in degrees of severity and corneal measurements.

Scleral Contact Lenses For Post Corneal Graft

Patients may be concerned that achieving a clear and comfortable vision will be nearly impossible following corneal transplant surgery. Although corneal transplants have a high success rate, they do not entirely cure the eye of disease. Patients will certainly notice dramatic improvements, but their vision will still need to be corrected.

It can take more than a year for the eye to recover from a corneal transplant, as it needs time to adapt to the new cornea. Because this adjustment is unpredictable, nearsightedness or astigmatism may develop. Even after complete recovery, prescription glasses or lenses may still be required. For this and other reasons (explained below), scleral lenses are the optimal choice for vision correction.

Here at Pacific Eye Doctors, we aim to provide the best possible vision for our patients who’ve had a corneal transplant. If you’ve undergone this procedure, speak with Dr. Schnarr to determine whether scleral contact lenses are the best choice for you.

Understanding Corneal Transplants

There are two common types of corneal transplants:

Penetrating keratoplasty, also called “full-thickness corneal transplant”, is when the full thickness of the cornea (the clear front surface of the eye) is replaced with healthy donor tissue.

Endothelial keratoplasty replaces only the diseased corneal tissue, leaving healthy tissue behind.

woried old manWhy Would Someone Need a Corneal Transplant?

A corneal transplant is generally recommended in the following cases:

  • For those with vision problems caused by the thinning of the cornea (generally due to keratoconus) and only after less invasive treatments have been proven ineffective
  • Scarred cornea caused by severe injuries or infections
  • Vision loss caused by cloudiness of the cornea, typically due to Fuchs dystrophy

Scleral Lenses & Post-Corneal Transplant Surgery

Corneal transplants don’t cure irregular corneas, as the transplant doesn’t fully adapt to the eye. Some eye doctors may recommend rigid gas permeable lenses (RGP’s), hybrid contact lenses, or scleral lenses for clear and comfortable vision.

Of all the options, scleral lenses are the optimal choice. The fully customized contact lens vaults entirely over the cornea without adding any pressure to it, while allowing the cornea to remain hydrated for ultimate healing and comfort. Furthermore, because they are larger in size than any other contact lens, they are less likely to shift and move around on the eyes, thus reducing the risk of irritation or abrasion.

We Fit Scleral Lenses and Other Specialty Contact Lenses

Getting fitted for scleral lenses after a corneal graft can be life-changing. It can allow you to comfortably and safely drive at night or resume playing a sport that you thought you’d have to give up.

If you’ve had a corneal transplant or plan to do so in the near future, know that clear and comfortable vision after the surgery is possible. Don’t miss out on incredible life experiences because of poor vision — call Pacific Eye Doctors today.
