If you have always wanted to wear contact lenses instead of glasses, but were told you aren't able to, then you're in luck. There is a special type of lens called scleral lens, which you can wear even if you have eye problems like an irregular cornea. Here is more information about these lenses and who can get them.
How are scleral lenses different?
Scleral lenses are contact lenses that cover your entire cornea instead of just a small part of the corneal surface. They will rest on the white of the eye, called the sclera. They offer some excellent benefits, including having a lower risk of complications, easy handling, and sharper vision. The larger size allows them to be more stable when sitting on the eye, and they rarely get accidentally dislodged from the eye. There are some people who can't wear the regular contact lenses, because with irregular corneas, they don't sit right. These can help.
What types of scleral lenses are there?
You can choose from a few types of scleral lenses, which vary based on their location and size. These include:
- Mini scleral lenses – The mini scleral lenses will cover the corneal surface in its entirely, resting on the anterior part of the sclera.
- Corneo-scleral lenses – Also called the semi-scleral lenses, these are larger than regular contact lenses, but don't reach quite as far as the mini scleral lenses. They sit between the cornea and sclera.
- Full scleral lenses – The largest type of scleral contact lenses are called full scleral lenses. These cover the largest area of the cornea and scleral.
Who needs scleral lenses?
The majority of people who experience vision problems and want contact lenses can get scleral lenses, though they are usually reserved for people who are denied the opportunity to wear regular contact lenses. If you have any of the following eye conditions, you are an ideal candidate for these lenses:
- Irregular corneas – If your cornea is shaped irregularly, you won't be able to wear regular contact lenses. However, with larger scleral lenses, they go past the cornea and sit on the sclera, offering more coverage and stability of the lenses.
- Dry eyes – With dry eyes, it can be hard to get the smaller contact lenses to fit just on your cornea. With the full scleral lenses, they would provide a tear reservoir for the front of your eye, which actually helps with the lack of moisture. This is due to the back surface of the lens in between the cornea and the sclera.
- Differently-shaped eyes – You may have a shape of eyes that cause regular contact lenses to become dislodged easily. This is corrected with all three types of scleral lenses.
