What Are Scleral Lenses and How Do They Work?

At Advanced Family Eye Care in Allentown, PA, we strive to provide our patients with the best vision solutions available. One such option is scleral lenses, which offer unique benefits, especially for those with specific eye conditions. Let us delve into what scleral lenses are and how they work to improve your vision and comfort.

What Are Scleral Lenses?

Scleral lenses are a type of contact lens designed to fit over the entire cornea, the clear, front part of your eye, and rest on the sclera, the white part surrounding it. Unlike traditional contact lenses, scleral lenses are larger in diameter, which allows them to cover a greater surface area.

How Do Scleral Lenses Work?

The magic behind scleral lenses lies in their design and functionality. Here is how they work:

1.            Vault Over the Cornea: Scleral lenses arch over your cornea, creating a space between the lens and the eye surface that is filled with a liquid reservoir. This design protects the cornea and provides a consistent, smooth surface for better vision.

2.            Provide a Cushion of Moisture: The liquid layer trapped beneath the scleral lens keeps your eye constantly hydrated. This is particularly beneficial for people with severe dry eyes or those who have trouble keeping their eyes moist.

3.            Correct Vision: By creating an even refractive surface, scleral lenses correct specific vision problems often caused by an irregularly shaped cornea, such as keratoconus. They can improve visual acuity by compensating for corneal irregularities.

Who Can Benefit from Scleral Lenses?

Scleral lenses are not just for anyone. They are especially beneficial if you have:

•             Keratoconus: A condition where the cornea becomes cone-shaped and irregular.

•             Severe Dry Eye: Difficulty retaining moisture due to various eye conditions or surgery.

•             Post-surgical Challenges: Issues resulting from eye surgery, where traditional contact lenses may no longer fit comfortably.

The Fitting Process

Getting fitted for scleral lenses involves a detailed eye exam and measurements to ensure a perfect fit. Our eye doctors utilize advanced technology to customize each lens, ensuring optimal comfort and vision correction.
