Specialty Contact Lenses

Specialty Contact Lenses

Prosthetic contact lenses are designed to improve the appearance of an eye that has been disfigured from an injury or eye disease. They can also be used to treat people with severe light sensitivity.

RGP lenses were the first type of lenses prescribed to people with conditions like keratoconus. They are also used for higher prescriptions as well as higher amounts of astigmatism. RGP lenses can give people great vision however can have some unwanted side effects. These include more lens awareness, debris under the lens and the lens becoming more easily dislodged.

Hybrid lenses are lenses that have a hard center like an RGP lens with a soft skirt surrounding it. The hard center vaults over the cornea and the soft skirt helps keep the lens in place. This lens design gives the patient the benefit of great vision, while the soft skirt helps stabilize the lens. The skirt gives the lens more comfort than a traditional RGP and it also prevents debris from getting under the lens. These lenses are often prescribed for patients with high amounts of astigmatism, keratoconus, post-refractive surgery and for other corneal ectasias and irregularities.

Scleral lenses are large diameter lenses that are a similar material to an RGP. Scleral lenses vault over top of the cornea creating a fluid reservoir between the cornea and the lens. The lens lands on the white part of the eye (the sclera), which is a less sensitive area of the eye. This causes a significant improvement in comfort over a standard RGP lens. The lens has a uniform curve, acting like a regular cornea and focuses all light to a single point on the retina. Scleral lenses leave a space between the surface of the cornea and the lens. This space is filled with saline which keeps the cornea hydrated throughout the day. As with hybrid lenses, they are best for people with high amounts of corneal astigmatism as well as other corneal irregularities. In addition to this, they are also used as a treatment for people with severe dry eye disease like Sjogren’s, or for individuals whose eyes are too dry for conventional contact lenses.
