Scleral Lenses

What are scleral lenses?

Scleral lenses are a rigid gas permeable contact lens that has a much larger diameter than a typical “hard” contact lens. The contact lens rests on the sclera, which is the white portion of the eye. Before insertion of the contact, the lens is filled with a preservative-free saline solution that serves as a fluid reservoir between the back surface of the contact and the front surface of the eye (the cornea). The fluid reservoir stays intact during the entire course of wear time, allowing optimum comfort and vision.

Why use a scleral lens?

Some corneal diseases/defects, such as Keratoconus, cause an irregular cornea. The irregularity causes decreased vision that may not be corrected fully with glasses and can lead to improper fits with traditional hard or soft contact lenses. By using a scleral lens, the fluid reservoir mimics a spherical front surface and can eliminate the irregular surface and increase clarity.


What types of corneal diseases/defects can be improved with Scleral Lenses?

Anyone can wear scleral lenses as desired, but the most common fits are designed for patients with Keratoconus (progressive bulging of the cornea), high amounts of astigmatism, corneal degenerations, and even severe dry eye.
