If you want to wear contact lenses but have had trouble wearing them in the past, or you’ve been told you are not a good candidate for contacts, scleral contact lenses may be the solution you are looking for.
These large-diameter gas permeable (GP) lenses offer the same advantages that conventional GP lenses have compared with soft contacts, including:
- Sharper vision
- Greater durability
- Easier handling
- Less risk of complications
They are called “scleral” lenses because, instead of covering only a portion of the cornea (like conventional GP lenses), these large GP lenses vault over the entire corneal surface and rest on the “white” of the eye (the sclera).
Because of their size, scleral lenses are more stable on the eye than conventional GP lenses — so they are less likely to accidentally dislodge from the eye. This stability also can make them more comfortable than conventional GP lenses; scleral lenses provide initial comfort similar to soft lenses, especially for sensitive eyes or irregularly shaped corneas.
Are Scleral Lenses For You?
Generally, anyone interested in achieving the best vision possible with contact lenses can be a candidate for scleral lenses. But scleral GP lenses are particularly helpful for the following conditions:
- Irregular corneas. 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 typically will provide sharper vision for these eyes.
- Hard-to-fit eyes. If your eyes cannot be comfortably fitted with conventional GP lenses or the shape of your eye causes the lenses to dislodge too easily from your eyes (during sports, for example), scleral lenses can provide a more comfortable and secure fit.
- Dry eyes. If your eyes are too dry for conventional contact lenses, scleral lenses can help. In particular, 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.
