Scleral Specialty Lenses for Keratoconus Q & A

by Diana Zabarko, OD

What is keratoconus?

Keratoconus of the eye is a condition of the cornea that causes the cornea to be misshapen, as parts of the cornea thin out and the structures of the eye bulge. This is a progressive condition that usually affects the area immediately in or around the cornea. This causes problems with vision, including increasing astigmatism.

This condition typically affects one eye, but can affect both. Because the shape of the cornea is irregular, using soft contacts or glasses to correct the problem isn’t always the best option. About 15% of those with keratoconus need a corneal replacement. For many, gas permeable contacts can help smooth the surface of the cornea and improve vision.

What are gas permeable contact lenses?

Gas permeable (GP) contact lenses are a type of lens used to help correct vision. These are made of a more rigid material than soft contacts. GP lenses fit the eye differently and allow a greater degree of oxygen to brush the surface of the eye.

Other benefits of GP lenses over other types of contact lenses include:

  • More durability
  • Sharper image
  • Lower risk of complications
  • Easier to handle and care for
  • Less likely to dry out the eye
  • Longer wear than soft contacts

GP contacts are generally healthier for eyes and present fewer complications, as they are easier to disinfect and keep clean. They are often a viable option for those who may not be able to wear soft lenses.

What are scleral lenses?

Scleral lenses are a type of GP lenses that are larger in diameter, and because of their size, these lenses rest on the sclera, or the white of the eye, rather than on top of the cornea. This means the lens is generally more stable and more comfortable than traditional GP lenses, and that it can help improve vision when other types of lenses can’t.

These types of lenses work well for those who are hard to fit with conventional lenses, those with dry eyes, and those with corneal irregularities, such as keratoconus.

In the case of severe keratoconus, the scleral lenses work by creating space above the misshapen cornea, which fills with tears. This process smoothes out the surface of the cornea, improving your vision and visual sharpness.
