If you wear contact lenses in Pittsburgh, PA, you may have heard about scleral lenses. Scleral lenses aren’t called contact lenses because they don’t make contact with the eyes like regular contacts. They’re a special kind of lens designed for people with particular vision irregularities. It’s not possible for you to determine on your own whether you need scleral lenses; only an optometrist can do that. But the following is some helpful information about this special lens type.
Who Needs Scleral Lenses?
People with Keratoconus
Keratoconus causes a cone-like bulge on the cornea, leading to distorted vision. Scleral lenses are often the best solution for this condition, providing a smooth optical surface.
People with Severe Dry Eyes
Because of the tear reservoir between the lens and the cornea, scleral lenses can provide relief for patients with severely dry eyes.
People with Post-Corneal Transplant
Post-transplant patients often struggle with irregular astigmatism, which scleral lenses can effectively correct.
People Uncomfortable with Traditional Contacts
If traditional contact lenses are uncomfortable or continually dislodge from your eyes, scleral lenses may offer a more comfortable and stable alternative.
What Are Scleral Lenses?
Scleral lenses are contact lenses that have an extra-large diameter. They cover a larger portion of the eye compared to regular contact lenses. They rest atop the white part of the eye, which is called the sclera. This is why scleral lenses have their name. The unique position creates a tear-filled kind of vault over the cornea. This unique design is particularly beneficial for individuals with specific corneal irregularities or severe dry eye syndrome.
Even if you fall into one of the categories mentioned above, you shouldn’t try to determine whether you should get scleral lenses. But if you are curious, you can ask youroptometrist in Pittsburgh, PA, at your next appointment.
