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 Park Professional Eyecare eye doctor in Bronx 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.

Frequently Asked Questions with Dr. Ralph Paternoster

 

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. Ralph Paternoster at Park Professional Eyecare to see whether scleral lenses are the right solution for you.

Our practice serves patients from Morris Park, Allerton, Parkchester, and East Bronx, New York and surrounding communities.

Frequently Asked Questions with Dr. Ralph Paternoster

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.

Frequently Asked Questions with Dr. Ralph Paternoster

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.
