The Boston Scleral Lens Prosthetic Device (BSLPD) is simply a scleral lens that has been given a proprietary name.Ĭustom lenses prescribed in our office have very positive outcomes. They cover the irregularly shaped cornea and feel more comfortable than prior designs. They rest on the white part of the eye (sclera) rather than on the cornea. Scleral and semi-scleral lenses are lenses that are about the size of a normal soft contact lens and made in gas permeable (GP) materials. At times, a soft lens can be used to restore sight but usually, special gas permeable contact lenses are needed to restore vision. Customized lenses are made specifically for that cornea, and this means better comfort and clarity. Special contact lenses specifically designed for keratoconus can reduce the need for a corneal transplant. This information is then used to build custom lenses to the unique corneal shape. Each cornea is unique in shape, similar to the uniqueness of your “fingerprint”. Keratoconus can be difficult to detect and the diagnosis of Keratoconus is commonly missed if the practitioner is unfamiliar with the early-stage symptoms of the disease.Ī special instrument called a Corneal Topographer measure 8,000 points of the cornea to give us a precise map. There is usually a high amount of astigmatism. As the condition worsens, there is more distortion in the cornea. Keratoconus affects about I person in every 2,000-3,000.Īs the cornea becomes more irregular in shape, individuals become more and more nearsighted, have more astigmatism, and become sensitive to glare and light. If affects both girls and boys and may be greater in one eye than the other. The most likely reason for keratoconus is genetic. There can be scarring (clouding) of the cornea which further makes it difficult to see and may necessitate a corneal transplant. Keratoconus can occur in either one or both eyes. Vision becomes worse depending on the amount of cornea that is affected. As light passes through the distorted cornea, it causes distorted vision. This often begins when someone is in their teens or 20’s. In Keratoconus, the normally round shaped cornea becomes thin and begins to bulge into a cone-like shape. The cornea is the front part or “cover” of the eye and is the first and most important surface when light enters into the eye. Keratoconus (ker-at-o-conus) is a progressive eye disease that affects the cornea.
