Some people prefer the convenience of using contact lenses but simply don’t feel comfortable when wearing them. This can be caused by various reasons, but fortunately, there are now different types of contact lenses designed for specific purposes.
Scleral lenses, for example, are ideal for certain types of patients. Continue reading to learn more about them.
Understanding Scleral Lenses
Scleral lenses are large-diameter, gas-permeable contact lenses that cover the sclera and vault over the cornea. They offer a smooth optical surface that aids in treating visual issues brought on by keratoconus and other irregularities in the cornea.
Unlike standard contact lenses, which sit on the cornea, scleral lenses are fitted to leave room between the lens and the cornea. An isotonic fluid is injected into the scleral lenses, and tears are stored in the area between the cornea and the rear side of the lens, keeping the eye moist. People with severe ocular diseases can find comfort in this feature, which helps combat dry eyes.
Do You Need Scleral Contact Lenses?
You might be suitable for scleral lenses if you have trouble seeing well with regular contacts or eyeglasses. They are not only for people with corneas that have uneven shapes. This type of contact lens has been a specialty treatment for a long time. However, in recent years, its application has grown to include a variety of eye and vision problems.
Some of these conditions have nothing to do with anomalies in the cornea. Below are a few of the conditions that can be fully or partially treated with scleral lenses:
- Complications resulting from LASIK surgery and corneal implants
- Corneal degeneration
- Corneal ectasia
- Dry eye treatment requiring refractive correction
- Eye abnormalities
- High astigmatism
