Scleral contact lenses are the ultimate contact lens technology for irregular corneas. They completely cover the cornea and only rest on the white of the eye “or sclera” making them incredibly comfortable. Because they are larger than traditional rigid gas permeable lenses, they provide more stable vision and are less likely to accidentally dislodge or fall out. Their overall size is very similar to that of soft contact lenses, which allows them to offer the superior vision performance of a rigid gas permeable or hard contact lens, but with comfort more similar to that of a soft contact lens.
- Cover the entire corneal surface
- Rest on the sclera, or “white,” of the eye
- Are larger and more stable than conventional GP lenses
- Are less likely to dislodge accidentally
- Are more comfortable than conventional GP lenses
- Provide initial comfort similar to or better than soft lenses
- Are an excellent choice for sensitive eyes or irregularly-shaped corneas
Advantages of Scleral Lenses
If you want to wear contact lenses, but have had trouble wearing them in the past, or you’ve been told you are not the right candidate for contacts, scleral contact lenses may be the solution you are looking for. These lenses are now available in bifocal designs too.
These large-diameter GP lenses offer the same advantages of conventional GP lenses compared with soft contacts, including:
- Sharper vision
- Greater durability
- Easier handling
- Less risk of complications
- Longer life of the contact lens
Types of Scleral Lenses
- Corneo-scleral lenses are much larger than conventional GP lenses and rest near the junction between the cornea and the sclera.
- Mini-scleral lenses cover the entire corneal surface and rest on the anterior sclera.
- Full scleral lenses provide the most significant amount of clearance between the back surface of the lens and the cornea.
