Have you ever been told that you can’t wear contact because your cornea is irregularly shaped or because of post surgical RK/ Lasik and or been diagnosed with keratoconus/pellucid marginal degeneration? If so, get a second opinion at the Meadows Family Eye Care. When you come, ask about scleral contact lenses.

What Are Scleral Contact Lenses?

Scleral contacts are gas permeable contact lenses that have a large diameter. These lenses are designed to vault and sit on the “white” of the eye to give the irregular cornea a smoother surface. By providing a smooth surface, the lens can correct the vision issues caused by keratoconus or other irregularities. Another benefit to these lenses is they act as a fluid container for those who suffer from dry eyes and can not wear standard contact lenses. A lot of the time they can give significantly better vision than glasses.

Types of Scleral Contact Lenses

While larger than the standard contact lens, the scleral contact lens is still gas permeable. The sizes of these lenses can range from from 14.5mm all the way up to 24mm. Anything below 18mm is considered mini. With the average human cornea being 11.8mm, even the smallest scleral lens covers the entire corneal surface. This is different from most standard contact lens that usually only cover up to 80% of the cornea.
The size of the lens used is usually determined by the complexity of the eye condition. With mild forms of astigmatism and keratoconus, smaller scleral lenses can be used. Smaller scleral lens are easier to apply, require less care and can cost less. During your contact lens exam, your eye care professional will decide which type and size lens you need.

Scleral Contacts Lenses to Treat Keratoconus and Other Vision Conditions

While standard contact lens may be used in the case of keratoconus, issues can arise if the lens doesn’t properly center on the eye or moves when blinking occurs. Switching to a large diameter scleral contact lens may be the solution. Having a contact lens that rest on the less sensitive surface of the sclera can give relief and comfort to someone with keratinous. The scleral lens is designed to fit with minimum movement during blinks, which makes for a more stable and comfortable lens. Scleral contact lenses not only help those with Keratoconus but also those with other eye problems as well. If you suffer from severe dry eyes, have undergone a cornea transplant or even have Sjogren’s syndrome, scleral contact lenses may work for you.

Cost of Scleral Contact Lens

Scleral lens are custom made for each user which means they are going to be more expensive than the standard contact lens.
