Scleral Lenses - Great News!

If you are looking to wear contact lenses but have always had problems with comfort or have been told you'll never be able to wear contact lenses because of an irregularly shaped cornea or other eye problem, it may be time to look into a type of contact lens known as a “scleral lens.”Scleral contact lenses are large diameter rigid gas permeable contact lenses designed to pass over the cornea entirely, resting comfortably on the white of your eye, also known as the sclera. This allows scleral lenses to essentially replace the irregular surface of the cornea with a perfectly formed optical surface, giving you the kind of perfectly crisp vision you may not even be able to accomplish at all with eyeglasses or other forms of vision correction. This extra area also allows the lens to be a liquid reservoir to provide extra comfort for those who otherwise may have comfort issues with regular contact lenses.
Scleral lenses are noticeably larger than normal gas permeable lenses, varying in size from 14.5 mm to 24 mm across. The size of the scleral lens that a person needs is often determined by how complex their eye condition is. Mild keratoconus and abnormal astigmatism are usually considered less complicated and tend to require smaller, less costly, scleral lenses, whereas more advanced cases of keratoconus, severe and chronic dry eyes or advanced ocular diseases often are considered more complicated to treat, and usually require larger, more costly, scleral lenses.
Scleral lenses are always custom made to fit the unique contours of your eye, so fitting of this type of specialty lens requires a specific expertise and a greater amount of time fitting than with standard gas permeable and soft contact lenses. In many cases, a digital map of your cornea will by created, displaying for your optometrist an image referred to as your “corneal topography.” This will help your eye doctor more easily find the right fit for you, and reduce the number of trial pairs and the amount of time spent in fitting.
Because of the increased amount of time that is required to obtain a corneal topography and customize a scleral lens that works best and is most comfortable for your eyes, as well as the larger material cost to produce, scleral lenses can be significantly more expensive than traditional gas permeable and soft contact lenses. Despite this, scleral lenses still remain the most comfortable and, in many cases, only way, to obtain comfortable, accurate vision for those suffering from severe dry eye, keratoconus and other similar eye conditions.We have a unique library of scleral contact lens solutions for you.

Are you one of the 5 patient types that would likely benefit from a scleral lens?

Candidates Include Patients with:

  1. Allergies
  2. High or complicated prescriptions that have been told they can't wear contact lenses.
  3. Unsuccessful history with other lenses either due to poor comfort or poor vision.
  4. Keratoconus or any type of corneal degeneration or dystrophy, transplants, scarring or trauma or post-LASIK complications.
  5. Dry eyes or high sensitivity to light or Steve Johnson Syndrome.

What are the 5 main benefits of a scleral lens vs. a regular lens?

  1. Easier to insert and remove.
  2. Improved, consistent quality of vision all day long.
  3. Better comfort. Other lenses may dry out and get uncomfortable.
  4. Longer lasting. With proper maintenance, they can last over a year.

What are three key differences in the scleral lens technology?

  1. The lens doesn't touch the cornea but rests on the sclera or the white part of the eye to increase comfort.
  2. Microscopic adjustments to the lenses can be made with new advanced manufacturing technology to customize the fit of each lens to each patient's unique needs.
  3. Can add highly customized, unique prescriptions onto each lens to provide even better vision.

Special Instances That Can Benefit from Scleral Lenses

icon-legalblindness
Legal Blindness:
It is not uncommon for someone who is legally blind from a corneal irregularity to regain great vision. This lens design provides a protective cushion of saline that can reduce pain and photosensitivity caused by other lens designs.

icon-sports
Sports:
Scleral lenses are great for athletes who require excellent acuity and a stable lens fit while they are physically active.

They are also useful in situations where other contact lens types are not effective or appropriate, including dusty environments and contact sports.

icon-protective
Protective & Therapeutic:
Scleral lenses can provide hydration to the cornea in severe cases of dry eye and ocular pemphigoid.

They can also help in keeping the eye hydrated in conditions where the eyelids do not close properly such as facial nerve palsy, trauma, or ptosis.
