Scleral Contact Lenses are noticeably larger than standard gas permeable (GP) contacts. They have a diameter equal to or greater than that of soft contact lenses. The smallest sclerals are approximately 14.5 mm in diameter and the largest can be up to 24 mm. Instead of covering only a portion of the cornea, these large GP lenses vault over the entire corneal surface and rest on the “white” of the eye (the sclera).

Scleral lenses are a good choice for people who require larger-than-normal GP lenses for stability and comfort. They are frequently used when contact lenses are needed after LASIK or to correct irregular astigmatism, such as Keratoconus.

Why Scleral?

Vision problems caused by an irregularly shaped cornea — whether naturally occurring, due to an eye condition such as Keratoconus, or resulting from eye surgery — typically cannot be fully corrected with glasses or soft contact lenses. Scleral lenses can provide sharper vision for these such cases.

Scleral lenses can provide a more comfortable & secure fit if your eyes cannot be comfortably fit with conventional lenses. For example, if the shape of your eye causes normal lenses to dislodge easily from your eyes during sports or other physical activity, scleral lenses may be a great option for you.

If your eyes are too dry for conventional contact lenses, scleral lenses can help! The generous space between the back surface of full scleral lenses and the cornea acts as a tear reservoir to keep the front of your eye more moist and comfortable throughout the day.

Scleral Lens

Types of Scleral Contacts

  • Corneo-Scleral / Semi-Scleral Lenses: Much larger larger than conventional GP lenses and rest near the junction between the cornea and the sclera
  • Mini-Scleral Lenses: Vault over the entire corneal surface and rest on the anterior sclera
  • Full Scleral Lenses: The largest scleral lenses and provide the greatest amount of clearance between the back surface of the lens and the cornea
