Scleral contact lenses

In a perfect world, everyone would be able to wear conventional soft lenses. Soft lenses are the least expensive and most convenient option. Unfortunately, we don't live in a perfect world and some people have eye conditions that require them to wear specialty lenses. Scleral lenses are a specialty lens we often prescribe at Today's Vision Cypress.

What Are Scleral Contact Lenses?

Scleral contacts are large-diameter gas permeable contacts. Most contacts sit on the cornea, but scleral contacts are different. These lenses rest on the white of your eye, called the sclera. The part of the contacts that contain the prescription vaults over the eye.

Conditions Treated With Scleral Lenses

There are a few conditions that scleral contact lenses are typically prescribed for, including:

  • Keratoconus: This condition occurs when your cornea isn't strong enough to hold its round shape, which causes it to bulge into a cone shape. Because the cornea is misshapen, wearing soft contacts is not an option.
  • Dry eye syndrome: Dry eye syndrome occurs when your eyes don't produce enough natural tears to keep your eyes lubricated. Because contact lenses can dry out your eyes, people with severe dry eyes cannot wear conventional soft contacts.
  • Astigmatism: Astigmatism is a common refractive error that is characterized by an abnormal curvature of the cornea. Patients with astigmatism are unable to wear traditional soft contact lenses.
  • Post-LASIK: Some people require some degree of correction after LASIK. Since soft contacts can dry your eyes out, many people cannot wear them after LASIK.

Different Types Of Scleral Contacts

There are three different types of scleral lenses.

  • Mini scleral lenses: These contacts vault over the cornea and rest on the anterior space.
  • Full scleral lenses: These are the largest type of scleral lens and they provide the most coverage. This type is often used for severe dry eye syndrome, ocular disease, and advanced keratoconus.
  • Corneo-scleral/Semi-scleral lenses: These lenses are larger than conventional gas permeable lenses and rest where the cornea and the sclera meet. They are often used for post-LASIK patients and patients with severe astigmatism.
